Separable Base Specifications (Common to both models)
Usage Features
Maintenance Features

The device described in this manual is a FW-2-E Conventional Photoelectric Smoke Detector and Base and a FW-2-E-H Conventional Photoelectric Smoke and Heat Detector and Base. These devices are designed to detect smoke and, in the case of the FW-2-E-H, heat, as part of a fire alarm system. They are intended for use in commercial and industrial settings.

Function Description:

Both models utilize an infrared (IR) LED and a blue LED, along with a photodiode, to detect smoke. The photoelectric smoke sensor is designed to reduce sensitivity to false alarms and increase sensitivity to fire conditions. This is achieved by using a smooth ceiling mount and, in some cases, by reducing spacing at the perpendicular of the obstructions. The FW-2-E-H model adds a thermistor for heat detection, providing an additional layer of protection.

The detectors are designed to be connected to a control panel. When smoke or heat is detected, the device signals the control panel, initiating an alarm condition. The manual emphasizes that these devices are part of a life safety system and must be installed, maintained, and operated in accordance with all applicable national, state, and local codes and authorities having jurisdiction.

Base ID: HB-J5
Alarm Current: 150mA (max) @15.0 - 33.0V max
Mounting Box: 4" Octagonal / 4" Square

Usage Features:

Wiring Detectors: The manual provides a diagram for wiring the detectors to a 3M Weatherban #606 nonflammable sealing compound (or equivalent) to reduce the stack effect. The detector base includes terminals for connection to the control panel.
Placement of Detectors: Detailed guidelines are provided for detector placement, emphasizing compliance with local codes and the authority having jurisdiction. Factors to consider include:
- Contents of space
- Involved height of ceiling
- Surface condition of ceiling
- Total area
- Air movement (stratification)
- Vent location (velocities and dilution)
- Deflections and obstructions
Spacing: One smoke detector covers approximately 450 to 900 square feet. For smooth ceilings, detectors can be placed on 30-foot centers. For ceilings with beams or other obstructions exceeding 8" but less than 18", reduced spacing at the perpendicular of the obstructions is recommended. For obstructions exceeding 18", additional detectors may be required.
Testing: The manual outlines a testing procedure for the FW-2-E/FW-2-E-H detectors. This involves:
1. Holding a magnet (2lb pull force min) on the detector as shown.
2. The detector will blink red.
3. The detector will cause the alarm to illuminate a continuous red LED.
4. For no-go: The detector will continue to blink red and never alarm or latch red.
5. Upon reset, the detector LED should flash Green.
Caution on Aerosol Smoke Contaminants: The manual warns against using aerosol smoke contaminants for testing, as they can damage the detector. Instead, it recommends using Sabre aerosol cans or Testifier 1000/1001 or 2000/2001 with TS3 smoke capsules/heat setting per manufacturer's instructions.

Maintenance Features:

Cleaning: The manual advises that dry compressed air can be used to remove dust from a detector. If the detector fails to initiate an alarm condition or initiation of a false alarm condition, it should be removed from service.
Testing: Regular testing is crucial for effective operation. The manual specifies that combustion products must enter the outer chamber for the detector to operate efficiently. Airflow, stratification, velocity, stagnation, and migration all affect the efficiency and accuracy of the detector. Users should use an air flow meter to determine the movement of air within a structure. Compliance with local codes and ordinances for maintenance requirements is emphasized, including annual functional testing and visual inspection.
Troubleshooting: Prior to testing any detector, care should be exercised to ensure proper disabling of live signals and notification circuits of the fire alarm control panel. Failure to do so may result in false alarm signals which could place life and property in jeopardy.

The manual also includes a "CAUTION" section emphasizing that all life safety devices, including fire alarm equipment, must be installed, operated, and maintained according to manufacturer's instructions and all applicable codes. Failure to follow these instructions may result in failure of the detector to initiate an alarm condition. Napco Security Systems, Inc. disclaims responsibility for any devices that have been improperly installed, used, or maintained.
