The 4098 Duct Detector/Sensors (see Figure 1) are designed to sample air and
detect smoke in air ducts. The 4098 Duct Detector/Sensors are available in the
following configurations:
•
4098-9685 Two-Wire Duct Detector supplied with the 4098-9601
Photoelectric Detector
•
4098-9686 Four-Wire Duct Detector supplied with the 4098-9601
Photoelectric Detector
•
4098-9688 Two-Wire Duct Detector with Relay Drive supplied with the
4098-9601 Photoelectric Detector
•
4098-9755 Two-Wire Duct Sensor supplied with the 4098-9714 Photo
Smoke Sensor
•
4098-9756 Four-Wire Duct Sensor supplied with the 4098-9714 Photo
Smoke Sensor
The 4098-9685, 4098-9686, and 4098-9688 Duct Detectors have a red LED on
the detector for “POWER ON” indication (red LED flashing) or for “ALARM”
indication (red LED “ON” steady).
The 4098-9755 and 4098-9756 Duct Sensors have a red LED on the PCB
assembly for “POWER ON” indication (red LED flashing) or for “ALARM” or
“TROUBLE” indication (red LED “ON” Steady).
The 4098-9686 Four-Wire Duct Detector and 4098-9756 Four-Wire Duct
Sensor have a yellow LED that indicates an short or open condition on the
supervised control zone (yellow LED “ON” steady), a trouble is also reported to
the panel during a short or open condition.
The 4098-9686 and 4098-9756 provide a supervised control circuit to drive up
to fifteen (15) remote 4098-9843 relays for alarm, supervisory, and control
functions. The 4098-9688 Two-Wire Duct Detector provides a supervised relay
control output that can drive one (1) 4098-9841 remote relay.
For detailed information on using smoke detectors/sensors in air distribution
systems, see NFPA 90A.
