Bosch Analog Multicriteria Detector Dual-Photo/Heat/CO

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.

Functions

Address Range
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.

Indicator LED
Indicator LED 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 polling indicator. In the event of an alarm condition, the detector LED will always show a steady red light.

Modular Construction
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.

Multi sensor detector
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 Degree F.

Multi-criteria detector
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.

Carbon monoxide sensors
Detectors that contain carbon monoxide (CO) sensors must not be used as stand-alone CO detectors. The CO sensor is supplied to confirm the presence of CO as a by-product of combustion thereby reducing false alarms, but not to confirm the presence of CO as a hazardous gas.

Programming
Local programming is carried out at the panel keypad or by computer through a Web browser. Remote programming is carried out through a Web browser.

Sensitivity Calibration and Compensation
The sensitivity of the smoke sensor is programmable with 12 levels from which to choose. Throughout its normal life cycle, the smoke detector monitors itself against its factory calibrated level and periodically compensates itself to keep the sensitivity at its programmed level. When the detector is excessively contaminated, this condition will be annunciated at the control panel.
