Galaxy 2 Series Installation Manual
GSM Module (2–44+ Only)
A Dedicated GSM telecommunication interface can be connected to the Galaxy 2 series control panel to
allow an alternative communication path to the PSTN telephone line. The GSM module is installed as follows.
CAUTION: Install the control panel with the GSM Module at least 1.5 m from any wireless
peripheral device. This will avoid interference generated by the GSM. Do not
install the module in the immediate proximity of a sound source (loudspeaker, TV
set, Hi-fi chain etc.)
1. Remove all power from the control panel and remove the control panel PCB from the enclosure.
2. With the control panel PCB still removed, remove the knock-out in the top-centre of the enclosure using
broad-nose pliers, gripping the full length of the knock-out tab and bending it sharply downwards.
3. Slide the GSM antenna into the slot in the top of the enclosure and lock into place with the locking tab
provided.
4. Fit the co-axial antenna lead to the GSM module.
5. Remove the two-way jumper fitted to two of the four audio pins on the rear of the PCB.
6. Using the three stand-offs supplied with the GSM module, fit the module to the rear of the control panel
PCB, taking care to route the two power leads to the GSM power terminals on the corner of the control
panel PCB.
