Honeywell GWXP95-DM Analog Addressable Discovery Multi-Sensor
The Analog Addressable Discovery Multi-Sensor (XP95-DM) detector is designed to operate with the Gamewell-FCI 600 Series and ILI95-E3 Series analog addressable fire alarm control panels.
The XP95-DM includes both photoelectric and thermal sensing elements integrated into a single device.
The XP95-DM operates so that it digitally transmits its address to the fire alarm control panel (FACP).
In addition, it transmits the analog value from both the photoelectric chamber and the thermal sensor for analysis. The high-level algorithms, designed to prevent false alarms, process the signals originating from the combined sensors.
The detector is automatically programmed for pure heat detection, pure smoke detection, or a combination of both detections that are dependent on ambient conditions.
All XP95 detectors have identical external dimensions and can be installed in all base options. The dual Light-Emitting Diodes (LEDs) located on either side of the housing visibly transmit polling and external alarm status.
The thermal element of the XP95DM is designed for the free movement of air flowing around the exposed thermistor.
The photoelectric detection element uses a patented smoke chamber and an infrared smoke-sensing feature to obtain maximum sensitivity and selectivity.
The XP95-DM Multi-Sensor has both a photoelectric detection chamber and a thermal sensing element.
The infrared LED in the photoelectric detection chamber emits a burst of collimated light once per second or emits the light in response to direct interrogation by the FACP. In clean air, the photo diode receives no light from the emitter.
When the smoke enters the chamber, it scatters light from the emitter onto the photo diode that is proportional to the smoke's characteristics and density.
As the smoke content in the chamber increases, the signal from the photo diode increases. The XP95-DM monitors the temperature using a single thermistor which provides a voltage output that is proportional to the external air temperature.
The thermistor is calibrated to the normal analog value at a temperature of 25°C (77°F). Depending on how you configured the detector programming, the on-board electronics process the values from each sensing element.
The XP95-DM Discovery multi-sensor detector is automatically programmed for pure heat detection, pure smoke detection, or a combination of both.
