Press this power switch to activate the detector. When the unit is first turned on the horn is muted until the detector has warmed up.

This symbol will flash for approximately 10 seconds and the pulsed alarm will sound one pulse, indicating the system is warming up and testing itself.

The display will show this symbol when the warm up is complete and no fumes are present.

If you have a leak, and the concentration reaches 15% to 25% of the lower explosive level, this symbol will flash, OK symbol will turn off & alarm will sound until the fumes are cleared.

Press this switch if you want to stop the alarm while you correct the problem. The horn will automatically start again in approximately 70 seconds.

This detector also warns you when your battery is losing its charge. The display shows this symbol when the voltage drops to 10VDC and the horn gives a short pulse every 8 seconds.

Testing
This detector can be tested by injecting gas (no flame) from a butane lighter for 5 seconds into the sensor(s). This test should be done weekly to ensure proper operation of the detector.

If the detector goes through its normal start up cycle and testing the sensor doesn't trigger an alarm, it's an indication that the sensor is faulty. It should be returned to your dealer for warranty replacement or, if your warranty has expired, you can obtain a new sensor from your dealer or directly from us. See sensor details in the GS/5 product section.

Warning!
The sensors used in all of our detectors can be contaminated by water. If the sensor gets wet, the water causes a short circuit in the sensor. The result is the same as propane completing the sensor circuit and triggers an alarm even when no propane is present. It is extremely important to keep the sensor dry at all times. Read more in our Sensor section.

If you have determined that you don't have a leak and the sensor continues in the alarm mode, it is likely that you have a contaminated sensor. It should be returned to your dealer for warranty replacement or, if your warranty has expired, you can obtain a new sensor from your dealer or directly from us. See sensor details on how it works.
