GEMINIGX20e

The Gemini GX20e is intended as a standalone battery powered fire alarm. Each unit is independently powered from two 9v PP3 size Alkaline batteries.

Installation as a Standalone Unit

GX20e is supplied with two operating keys, a TEST key, batteries and fixing screws etc. Remove the front panel and fix the Back Box to any solid surface using the screws

provided or with some other suitable form of fixing. Ensure that an EOL link is fitted. Clip the batteries on to the red and black leads. Switch to SILENCE & BATTERY TEST

– the sounder will sound and the LEDs will flash alternate Fire & Fault. Return the Keyswitch to RE-START & NORMAL. Test the fire alarm by inserting the black plastic

test key in to the underside of the call point, this will simulate an alarm condition. The sounder and the fire LEDs will flash alternatively. Turn the Keyswitch to SILENCE.

The fire LEDs will flash and the sounder will give a short warning bleep every 30 seconds. Remove the test key and restore the Keyswitch to its NORMAL position.

Installation Interconnected

A two wire connection is required between each unit. It is NOT possible to spur off, the circuit must run through all the units. It is best to install each unit and test it as a

standalone unit before making the interconnections. Once it is confirmed that each unit functions correctly disconnect the batteries and make the two wire

connections. DO NOT FORGET that the last unit must have the EOL link. Starting with the end of line unit refit the batteries and test each unit in turn. It is not

recommended that more than four units are interconnected.

A cable fault and battery fault monitor are included to detect cable disconnection or short circuit. The batteries should last for at least 12 months depending on the
