Compatible devices
This detector is compatible with UL/ULC Listed DSC
Control Panels and Qolsys IQ Panel 2+. For UL/ULC
installations use this device only in conjunction with
compatible IQ2 wireless receivers and PowerG
receivers. Transmissions occur at approximately 915
MHz (912 MHz to 919 MHz).
Operation
During normal operation, the green LED flashes every 12 seconds.
The detector goes into alarm when the heat level exceeds 135 ºF / 57.5 ºC and automatically
restores when the heat level falls below the threshold. The detector also goes into alarm
when the temperature rapidly increases over a short period of time. During an alarm, the
LED flashes once per second and the sounder emits the evacuation temporal pattern.
Detector trouble
If the detector has a general fault, the yellow LED blinks once every four seconds and
emits a chirp every 48 seconds. After four hours, the panel displays a fire trouble message.
