Description
Simplex 4098-9756 4-Wire Duct Sensor Supplied With The 4098-9714 Photo Smoke Sensor.
Model 4098-9756 Simplex.
- Duct sensor housing with supervised output for multiple remote relays; requires separate 24 VDC; includes one relay.
- Relay output is under panel control.
- At the panel, relay output can be activated manually or in response to a separate alarm or other input.
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.
Diagnostic LEDs (on interface board):
- Red Alarm/Trouble LED for sensor status and communications polling display.
- Yellow LED for open or shorted trouble indication of supervised relay control.
4098-9756 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.
- Optional weatherproof enclosure is available separately (refer to data sheet S4098-0032).

Control Panel Selection.
Peak activity per sensor is stored to assist in evaluating specific locations. The alarm set point for each sensor is determined at the control panel, selectable as the individual application requires.
Sensor Status LED.
Each sensor housing’s red status LED (located on the electrical interface board) pulses to indicate communications with the panel. If the control panel determines that a sensor is in alarm, or that it is dirty or has some other type of trouble, the details are annunciated at the control panel and that sensor housing’s status LED will be turned on steadily.
During a system alarm, the control panel will control the LEDs such that an LED indicating a trouble will return to pulsing to help identify any alarmed sensors. (Remote Status/Alarm LEDs track the operation of the sensor housing LED.)
