RFI draft: 📄 FA-01 Schedule Text: DRAWING INDEX — page 1

Summary: The Fire Alarm Riser Diagram (FA-11) assigns the PRIMARY RECALL function to device M1-L2-76 and the SMOKE CURTAIN function to device M1-L2-77. However, the Level 2 Floor Plan (FA-03) shows M1-L2-76 and M1-L2-77 as standard smoke detectors ('S' type) located near Stair 2, with no elevator recall or smoke curtain function label. The floor plan...

Why it matters: Incorrect address assignment for elevator recall and smoke curtain control is a critical life-safety issue. If the fire alarm panel is programmed per the riser diagram, the wrong smoke detectors (near Stair 2 rather than the elevator lobby) would trigger elevator recall and smoke curtain deployment. This could compromise firefighter elevator...

Suggested next step: Request the fire alarm designer to clarify the correct device addresses for the Level 2 PRIMARY RECALL and SMOKE CURTAIN functions. Specifically: (1) Should PRIMARY RECALL be at address M1-L2-76 (per riser diagram FA-11) or M1-L2-78 (per floor plan FA-03)? (2) Should SMOKE CURTAIN be at address M1-L2-77 (per riser diagram FA-11) or near...

Specifically: (1) Should PRIMARY RECALL be at address M1-L2-76 (per riser diagram FA-11) or M1-L2-78 (per floor plan FA-03)? (2) Should SMOKE CURTAIN be at address...

Summary: The Level 8 floor plan (FA-09) assigns VESDA panel monitoring points to addresses TP-1·M2-L4·72 through TP-1·M2-L4·79 (MONITOR 1–8 VESDA PANEL), elevator primary recall to M2-L4•81, and smoke curtain control to M2-L4•82. The eighth floor riser diagram (FA-14) assigns the identical VESDA monitoring functions to M2-L4-1 through M2-L4-8, primary...

Why it matters: SLC point addresses are programmed into the fire alarm control panel and must exactly match the field device configuration. Mismatched addresses between the plan and riser will cause confusion during installation, programming, and commissioning. VESDA monitoring, elevator recall, and smoke curtain control are critical life-safety functions;...

Suggested next step: Request clarification on the correct M2-L4 SLC point addresses for all eighth floor devices. Specifically, confirm whether the VESDA panel monitors are addressed as TP-1·M2-L4·72 through TP-1·M2-L4·79 (per FA-09) or M2-L4-1 through M2-L4-8 (per FA-14), and whether primary recall and smoke curtain are at M2-L4•81/M2-L4•82 (per FA-09) or...

Specifically, confirm whether the VESDA panel monitors are addressed as TP-1·M2-L4·72 through TP-1·M2-L4·79 (per FA-09) or M2-L4-1 through M2-L4-8 (per FA-14), and whether primary recall and smoke...

Summary: The Level 6 floor plan (FA-07) assigns the elevator PRIMARY RECALL function to module M2-L2·24 and the SMOKE CURTAIN function to module M2-L2·25 at the elevator lobby. However, the Sixth Floor riser diagram (FA-13) assigns PRIMARY RECALL to M2-L2•2 and SMOKE CURTAIN to M2-L2•3. Furthermore, the riser diagram labels M2-L2•24 and M2-L2•25 as AIM...

Why it matters: Elevator recall and smoke curtain deployment are critical life-safety functions required by code. If modules are programmed to incorrect SLC addresses, fire department elevator recall and automatic smoke curtain activation will not function during a fire event. This conflict will cause failures during fire alarm acceptance testing and AHJ...

Suggested next step: Request the fire alarm designer to reconcile the M2-L2 SLC module addressing between the Level 6 floor plan (FA-07) and the Sixth Floor riser diagram (FA-13). Specifically clarify: (1) the correct module addresses for PRIMARY RECALL and SMOKE CURTAIN functions at the elevator lobby, (2) the correct module addresses for AIM devices at Stair 1,...

Specifically clarify: (1) the correct module addresses for PRIMARY RECALL and SMOKE CURTAIN functions at the elevator lobby, (2) the...

Summary: The fire alarm riser diagram shows three AOM (Addressable Output Module) relay outputs for elevator Phase I Emergency Recall: M1-L1·31 'PRIMARY RECALL' (designated level output), M1-L1·32 'ALTERNATE RECALL' (alternate level output), and M1-L1·33 'FIREMAN'S HAT' (firefighter visual indicator at the elevator landing). NFPA 72-2019 Section 21.3.14...

Why it matters: The absence of the third elevator recall output will fail AHJ inspection during fire alarm acceptance testing. Per ASME A17.1 Section 2.27 (referenced by NFPA 72 21.3.14), the elevator controller requires three distinct input signals to differentiate between lobby fire conditions, alternate level conditions, and machine room/control room fire...

Suggested next step: Request the fire alarm designer to add a dedicated AOM output module for the elevator machine room/machinery space/control space/control room associated output per NFPA 72-2019 Section 21.3.14(3), separate from the existing PRIMARY RECALL, ALTERNATE RECALL, and FIREMAN'S HAT outputs. Confirm the intended function of the FIREMAN'S HAT output...

Confirm the...

Summary: The Level 6 floor plan is identified as 'FLOOR PLAN, LEVEL6' and shows only a written scale note of 'Scale: 1/8\' = 1'-0\''. NFPA 72 requires each floor plan sheet to show a point of compass and a graphic representation of the scale used / graphic scale. This sheet does not provide those required per-sheet documentation elements.

Why it matters: Without a north arrow and graphic scale, the sheet does not meet the minimum NFPA 72 documentation requirements for fire alarm floor plan drawings. That can delay plan review, create orientation errors during coordination, and require sheet reissue before installation proceeds.

Suggested next step: Revise the Level 6 floor plan to add a point of compass (north arrow) and a true graphic scale on the sheet, and confirm that the added scale corresponds to the noted 'Scale: 1/8\' = 1'-0\'' plan.

Summary: The building is provided with a two-way telephone communications system as evidenced by Voice Station (VS) devices shown at Stair 1 (P1•M1-L1.3•57 and P1•M1-L1.3•58 with AIM/VS), Stair 2 (AIM/VS with P1-M1-L1.7-63), the elevator area (P1-M1-L1.4:59 VS), the garage (P1-M1-L1.5•60 AIM/VS), and the east service zone (P1•M1-L1.6•61 and...

Why it matters: The absence of a two-way telephone station in the fire pump room would prevent fire service personnel from communicating with the fire command center while operating or troubleshooting the fire pump during an emergency. This is a code compliance issue that would likely be flagged during plan review or inspection, causing a delay in permit...

Suggested next step: Request the fire alarm designer confirm whether a two-way telephone station (VS) or telephone jack is intended for the Fire Pump Room (B5) per NFPA 72 Section 24.8.12(7). If so, update the Level 1 floor plan to show the device location, address, and circuit routing within the fire pump room.

RFI draft: Request the fire alarm designer confirm whether a two-way telephone station (VS) or telephone jack is intended for the Fire Pump Room (B5) per NFPA 72 Section 24.8.12(7). If so, update the Level 1 floor plan to show the device location, address, and circuit routing within the fire pump room.

Summary: The scope states 'Provide (1) manual pull station and (1) remote annunciator in lobby,' and the legend also shows one addressable manual station. The sheet index shows floor plans from the first floor through the roof. NFPA 72 requires manual fire alarm boxes to be located within 5 ft of each exit doorway on each floor and requires additional...

Why it matters: This is a code compliance issue that is likely to be rejected in plan review and would require additional devices, wiring, and wall rough-in if discovered later in construction.

Suggested next step: Revise the fire alarm design to provide manual fire alarm boxes in compliance with NFPA 72 17.15.9.4 and 17.15.9.5 for the floors included in this project, or clarify the approved design basis if manual fire alarm boxes are not intended to be part of the required system.

RFI draft: Revise the fire alarm design to provide manual fire alarm boxes in compliance with NFPA 72 17.15.9.4 and 17.15.9.5 for the floors included in this project, or clarify the approved design basis if manual fire alarm boxes are not intended to be part of the required system.

Summary: In the C6-N3 point-to-point report, the device table identifies separate columns for 'VOLTAGE AT DEVICE' and 'TOTAL VOLTAGE DROP.' The same report also states 'STARTING CALC. VOLTAGE: 29' and 'END OF LINE VOLTAGE: 26.53' with 'MAX. VOLTAGE DROP: 2.47.' However, device C6-N3-19 is listed with a voltage at device of 27.18 and a total voltage drop...

Why it matters: NFPA 72 requires voltage drop calculations for notification appliance circuits. Because this required calculation is internally inconsistent, the report cannot be relied on to verify notification circuit performance during plan review or installation, which can require recalculation and reissuance before approval or construction proceeds.

Suggested next step: Please recalculate and reissue the TP-1 C6-N3 point-to-point report so the device-table values for voltage at device and total voltage drop are internally consistent with the stated starting voltage and end-of-line voltage.

RFI draft: Please recalculate and reissue the TP-1 C6-N3 point-to-point report so the device-table values for voltage at device and total voltage drop are internally consistent with the stated starting voltage and end-of-line voltage.

Summary: The TP-1 C8-N3 point-to-point report is internally inconsistent. It lists 'STARTING CALC. VOLTAGE: 29'. In the device table, C8-N3-18 shows 'VOLTAGE AT DEVICE' 26.64 with 'TOTAL VOLTAGE DROP' 2.36, but C8-N3-19 shows only 'VOLTAGE DROP FROM PREVIOUS' 0.01 while 'VOLTAGE AT DEVICE' drops to 24.96 even though 'TOTAL VOLTAGE DROP' is still 2.36....

Why it matters: Because the submitted voltage figures do not mathematically track the listed incremental and total drops, the actual operating voltage available on this circuit is unresolved. This can delay AHJ review and may require recalculation or circuit redesign before the notification appliances can be approved for installation.

Suggested next step: Please revise and reissue the TP-1 C8-N3 voltage-drop calculation report, identify the correct device and end-of-line voltages for the circuit, and confirm that the connected notification appliances comply with the corrected calculation.

RFI draft: Please revise and reissue the TP-1 C8-N3 voltage-drop calculation report, identify the correct device and end-of-line voltages for the circuit, and confirm that the connected notification appliances comply with the corrected calculation.

Summary: Circuit C2-N1 on FA-16 reports a Total Card Current of 7.80A, circuit C2-N2 on FA-16 reports 8.41A, and circuit C2-N3 on FA-17 reports 6.62A. All three circuits share the C2 card designation and should report the same Total Card Current value. The sum of their individual circuit currents (2.24 + 2.76 + 1.62 = 6.62A) matches only C2-N3's...

Why it matters: Incorrect Total Card Current values directly affect NAC power supply sizing, battery capacity calculations, and booster panel requirements. If the actual Card C2 load is 6.62A but one circuit report indicates 7.80A and another 8.41A, the installing contractor may improperly size backup batteries or select incorrect power supplies. This...

Suggested next step: Request the fire alarm designer to verify and correct the Total Card Current values for all C2 and C3 NAC circuits in the point-to-point reports. Confirm the correct card assignments for circuits C2-N1, C2-N2, C2-N3, C3-N1, and C3-N2, and regenerate the point-to-point reports with consistent and accurate Total Card Current figures across all...

Confirm the correct card assignments for circuits C2-N1, C2-N2, C2-N3, C3-N1, and C3-N2, and regenerate the point-to-point reports with consistent and...

Summary: Device C5-N2•8, located in the corridor near Stair 2 and the Trash Room, is tagged with only a visual output rating of 15 cd and no audible (dBA) rating. This tag is consistently shown across multiple overlapping views of the same area, confirming it is not a tile-edge truncation. All other comparable corridor notification appliances on this...

Why it matters: Without the documented audible output rating, the contractor may install a strobe-only device instead of the likely-intended combination speaker/strobe at this location. During acceptance testing, the sound pressure level at this corridor coverage area cannot be verified against the design intent, which would result in a failed inspection and...

Suggested next step: Request the designer confirm whether C5-N2•8 is intended to be a combination audible/visual notification appliance (like all other corridor devices on this floor) and provide the missing audible output rating (dBA) for this device. If the device is intentionally strobe-only, request justification for the omission of audible notification at this...

Summary: The same weatherproof notification appliance (A49AV-APPLW-O, 75CD) has a different per-unit alarm current draw on FA-26 (0.163A) versus FA-27 (0.165A). Both sheets reference the identical part number and candela rating, so the per-unit alarm current value should be consistent. The totals on each sheet are internally consistent with their...

Why it matters: While the 0.002A per-device difference has a negligible impact on the overall battery sizing for this project, the inconsistency introduces uncertainty about which value is the correct manufacturer-specified alarm current draw. This undermines confidence in the accuracy of both battery calculation sheets and could carry forward into future...

Suggested next step: Please confirm the correct per-unit alarm current draw for part A49AV-APPLW-O at 75CD candela setting per manufacturer data, and revise the affected battery calculation sheet(s) accordingly.

RFI draft: Please confirm the correct per-unit alarm current draw for part A49AV-APPLW-O at 75CD candela setting per manufacturer data, and revise the affected battery calculation sheet(s) accordingly.

Summary: On FA-28 (FACP cabinet), part number 5402 is listed once and consistently described as 'ES Expansion Power Supply (ES-XPS) with fan.' On FA-29 (Transponder 1 cabinet), the same part number 5402 is listed twice with conflicting descriptions: one entry reads 'ES Expansion Power Supply (ES-XPS) with fan' while the other reads 'ES Expansion Power...

Why it matters: During equipment procurement and installation, this inconsistency could lead to ordering an incorrect power supply configuration. If a fan is required for adequate cooling inside the Transponder 1 cabinet but a fanless unit is furnished based on the second listing, it could result in overheating, reduced equipment lifespan, or fire alarm system...

Suggested next step: Please clarify whether all model 5402 ES Expansion Power Supplies include fans. If there is a distinct fanless variant for the Transponder 1 cabinet, assign it a unique part number or clearly annotate the difference on FA-29. Confirm the correct specification for each 5402 unit shown in the Transponder 1 back plane layout.

If there is a distinct fanless variant for the Transponder 1 cabinet, assign it a unique part number or clearly annotate the difference on FA-29. Confirm the correct specification for each 5402 unit shown in the...

Summary: On FA-26, circuit P1-C3-N2 contains an entry for 1 × A49MT-APPLW with an alarm current draw of 0.055A. This contradicts all other instances of the same device (A49MT-APPLW, AUDIBLE NOTIFICATION APPLIANCES, WALL MOUNT HORN) on FA-27 and elsewhere on FA-26, where the alarm current is consistently listed as 0.099A. The 0.055A value matches the...

Why it matters: If the alarm current for this device was incorrectly entered as 0.055A instead of 0.099A, the Panel P1 total alarm current (30.72A) is understated by 0.044A. While the impact to this individual calculation is small, the discrepancy casts doubt on data accuracy across the battery calculation sheets and could affect the Authority Having...

Suggested next step: Please confirm the alarm current draw for the single A49MT-APPLW unit listed at 0.055A in circuit P1-C3-N2 on FA-26. Should this value be 0.099A consistent with all other A49MT-APPLW entries? If so, please update the Panel P1 battery calculation totals accordingly.
