Description
4098-9755 Simplex Duct Sensor Housing.
The 4098-9755 Simplex, Compact air duct sensor housing with a clear cover to monitor for the presence of smoke. Operation. Simplex® compact air duct smoke sensor housings provide TrueAlarm operation for the detection of smoke in air conditioning or ventilating ducts. Sampling tubes are installed into the duct allowing air to be directed to the smoke sensor mounted in the housing.
Includes factory installed TrueAlarm photoelectric smoke sensor and features:
- Individual sensor information processed by the host control panel to determine sensor status.
- Digital transmission of analog sensor values via IDNet or MAPNET II, 2-wire communications.
- Programmable sensitivity, consistent accuracy, environmental compensation, status testing, and monitoring of sensor dirt accumulation.
- Basic duct sensor housing (no relay output) powered by IDNet/MAPNET II communications.
4098-9755 Simplex General features:
- UL listed to Standard 268A.
- Clear cover allows visual inspection.
- Test ports provide functional smoke testing access with cover in place.
- Mounts to rectangular ducts or round ducts; minimum size is 8” (203 mm) square or 18” (457 mm) diameter.
- Magnetic test feature for alarm initiation at housing.
- The optional weatherproof enclosure is available separately.
Diagnostic LEDs (on interface board):
- Red Alarm/Trouble LED for sensor status and communications polling display.
4098-9755 Simplex Operation
Simplex® compact air duct smoke sensor housings provide TrueAlarm operation for the detection of smoke in air conditioning or ventilating ducts. Sampling tubes are installed into the duct allowing air to be directed to the smoke sensor mounted in the housing.
TrueAlarm Sensor Operation
Digital Communication of Analog Sensing. Analog information from the sensor is digitally communicated to the control panel where it is analyzed. The sensor input is stored and tracked as an average value with an alarm or abnormal condition being determined by comparing the sensor’s present value against its average.
