Basic Operation
The BoilerGuard has three buttons on the front:
Reset - The BoilerGuard Alarm 1 and 2 relays are activated depending on the sensor conditions. Following an alarm the reset button can be used to reset any relays that are set to latch including the Gas Valve output which will shut down if any sensor reaches Alarm 2..
Mute - If there are any gas alarms, this can be used to silence the panel for 15 minutes. If this is held in for 10 seconds, this will also reset any non-latching alarm relays for 2 minutes.
Test - The operation of the Test button is dependent on the panel status:
- If the panel is live without any alarm conditions, holding this button in for 10 seconds will enable the Fire Alarm bypass. The Fire Alarm interface will be ignored for 30 minutes to allow tests to be carried out.
- Following an alarm (prior to reset), holding the Test button for 5 seconds each will change the state of the Alarm 1, Alarm 2 and Fault relays.
