The FAP-440 Dual Ray Detectors are open-area smoke detectors of which some models are enhanced with heat or heat and CO sensors. These detectors work with the FPA 1000 Analog Addressable Fire Panels. Use the detector with the FAA 440 bases to provide general life safety and property protection.
Dual Ray Technology provides better particle size differentiation resulting in fewer false alarms.
Smoke threshold is adjustable and automatically compensated.
Rotary switch addressing.
Flexible work modes determined by the control panel.
Selectable base locking mechanism prevents malicious removal of the detector.
The FAP???440 Dual Ray Detectors have a valid address range from 1 to 254 which is set by rotary switches on the back of the detector.
The detector head has a multi???color LED to indicate status. To verify power to the detector and functioning communication of the analog addressable loop, the LED indicator flashes green when operating normally (polling). Through panel parameter setting, it is possible to turn on or off operation of the indicator. In the event of an alarm condition, the detector LED will always show a steady red light.
The FAP???440 Dual Ray Detectors are part of a two???piece modular design for detector assemblies. An FAP???440 Dual Ray Detector attaches to an FAA???440 Series Analog Base. The base’s security locking tab prevents any unauthorized detector removal from the base.
Advanced technology for false alarm reduction Dual ray technology:
The detector contains two emitters operating at different wavelengths. The different wavelengths enable better differentiation of particle sizes to distinguish smoke particles from other particles that may be present. This results in fewer false alarms due to dust, water vapor, or cigarette smoke.
The multi???sensor detector contains a photoelectric smoke sensor and a heat sensor. Either sensor can detect a fire and activate an alarm signal. The smoke threshold is adjustable (see Sensitivity Calibration and Compensation below) while the heat sensor’s threshold is set at 135°F.
The multi???criteria detector also contains smoke and heat sensors that work independently of each other, but in conjunction with the CO sensor. In this model, an alarm signal will be activated by either one or both of the sensors only if the CO level is also exceeded.
The control panel communicates to the detectors via the analog addressable loop, which allows the use of standard non???twisted, non???shielded wiring for the SLCs.
