GG-2

General Description

Installation

The GG-2 control panel is a two-channel controller designed to accept two 

4/20 mA input signals. It has a 24 VDC regulated power supply to power all 

industry standard 4/20 mA gas transmitters and audible/visual devices.
The GG-2 control panel provides continuous real-time monitoring of each 

sensor.
The backlit LCD display provides an at-a-glance status of gas concentrations 

and alarms.
The GG-2 control panel is assembled into a wall mounted enclosure 

designed for non-classified locations. The gas sensors (one or two) are 

installed at specific locations where gas is to be detected, up to 1,500 feet 

from the controller. They are electrically connected to the controller via three 

conductor cables.

The onboard relays have 10 second on/off time delays to prevent 

unnecessary cycling during a fault, warning or alarm condition.
All operator functions are performed from the keypad on the front of the 

panel.

Locating the GG-2 Control Panel

The important consideration when installing GG-2 control panel is that it 

must be easily accessible for operating personnel.

Installation Guidelines:

Mount controller on a solid surface with minimal vibration. If mounting on a 

wall with studs, the mounting screws should be screwed into the studs.

Mount controller thru the holes in the mounting flanges.

Mount controller in a general-purpose location only. Do not install in a 

hazardous environment.
Mount controller away from electromagnetic interference.
Protect controller from physical damage.
