GG-6
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 control panel until the initial start-up procedures are
completed.
After initial power-up, refer to sensor manual(s) for warmup times before
calibrating.
Because sensors are normally located at a distance from the control panel,
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-6 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. Pressing the ESC key anytime during Powerup mode will
bypass the timers and return to normal operating mode.
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 fumes, is connected to the proper input and
responds, causing appropriate alarm functions.
Time-Weighted Averaging
For applications which require TWA, this function can be enabled for any
or all of the connected sensors. More details are explained in the following
pages of this manual.
STEL and TWA Reset: Upon power-up, after saving changes to the GG-6
configuration, or after Resetting the STEL and TWA values, the sample
buffers are cleared (sample value = 0).
To Reset an individual channel STEL and TWA values, hold the <4> key and
press the <5> while on the desired Sensor Display Screen.
Keypad
All operator functions are performed from the membrane switches on the
front of the panel.
Silence Key: Pressing the Silence key will reset any relay which is
programmed to be silenceable in the Configuration/Action menu, until the
next event occurs.
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 Action in the
Configuration menu.
Note: It is possible to install remote mounted silence and/or reset switches.
