GG-2

Operation

Start-up

Before applying power, make a final check of all wiring for continuity, 

shorts, grounds, etc. It is usually best to disconnect external alarms and 

other equipment from the controller until the initial start-up procedures are 

completed.
After initial power-up, allow at least 12 hours for the sensors to stabilize 

before calibrating. Because sensors are normally located at a distance from 

the controller, the test time required and accuracy of the response checks 

will be improved if two people perform the start-up procedures and use 

radio contact.
The GG-2 control panel has a two-minute power-up delay during which 

the relays are held in their normal non-alarm state, after the application of 

power or a momentary power loss. This allows the sensors time to stabilize 

and disables the alarm functions.

Start-Up Test:

1) One person exposes each sensor to target gas.
2) The second person stays at the control unit to determine that each sensor,

 

when exposed to the gas, is connected to the proper input and responds, 

causing appropriate alarm functions.

Keypad

All operator functions are performed from the membrane switches on the 

front of the panel.

Silence Key:

 Pressing the Silence key will reset the horn relay and silence 

the buzzer, until the next event occurs. The horn relay is triggered by a fault 

or alarm condition, and can be programmed to trigger during a warning 

condition.

Reset: 

Pressing the Reset key will attempt to reset any latched relays. Any 

latched relays will not reset as long as there’s an existing warning or alarm 

condition. The latch-relay function can be enabled for each relay in the 

Configuration menu.
