Gas Release Panel Short Form Installation Guide
Item Numbers: 2983-0304
Connecting the Standby Batteries
CAUTION: There is a risk of explosion if the battery is replaced by
an incorrect type. Always dispose of used batteries in accordance
with the battery manufacturers’ instructions.
Note
: On a standard ‘as-supplied’ unit, PLK1 (‘Battery Monitoring’ link) is
not fitted and a fault will occur on initial power-up if fully charged batteries
are NOT connected. For the emergency standby power supply, only use
good quality, sealed VRLA batteries. Position and connect the 2x12Vdc,
7Ahr batteries, as shown in diagram (see right).
Connecting Circuits to the Main Control PCB
Terminate incoming and outgoing circuits at the Main Control PCB connectors (see Figure 2 overleaf).

Introduction
The Gas Release panel is a three zone automatic extinguisher control panel that is compliant with EN12094-1
and EN54-2. The panel incorporates a 3A, EN54-4 compliant switch mode PSU and a 128 x 64 pixel LCD that
facilitates system programming.
Installation
Location
The panel must be mounted indoors on a dry, flat surface in an area that is well ventilated. Ideally the panel
indicators should be at eye level and the ambient light level should allow the status of any indicators to be clearly
seen.
Fixing
Note : The panel’s base PCBs should be removed prior to first fix installation.
Using the five mounting holes provided, fix the base securely onto a wall. The mounting holes are suitable for
use with No.8-10, or 4-5mm countersunk screws. Assess the condition and construction of the wall and use
suitable screw fixings. Any dust or swarf created during the fixing process must be kept out of the enclosure and
care must be taken not to damage any wiring or components.
Wiring and Cable Entry
All wiring should be installed in accordance with the current edition of the IEE Wiring
Regulations (BS7671), or the relevant national standards.
The requirement for the mains supply to the panel is fixed wiring, using 3-core cable (no
less than 1mm
2
and no greater than 2.5mm
2
), or a suitable three conductor system, fed
from an isolating switched spur, fused at 3A.
In order to maintain cable segregation, the incoming mains cable should be fed into the
panel via the top right hand side knockouts (provided on the base unit). Knockouts
should be removed with a sharp, light tap using a flat 6mm broadsided screwdriver as
shown in diagram (see right). Always ensure that if a knockout is removed, the hole is
filled with a good quality 20mm cable gland. Any unused knockouts must be securely
blanked off.
WARNING: DO NOT ATTEMPT TO CONNECT THE MAINS SUPPLY TO THE POWER SUPPLY PCB UNTIL
ALL PCBs ARE SECURELY INSTALLED IN THE ENCLOSURE.
Connecting Mains Supply to the Power Supply PCB
Terminate the mains cable at the Power Supply PCB connector CONN1 (see Figure 1 below).
