Two Shock sensors with REED on one zone / cable

Villan11

Hi All,

Am converting my garage into a room and have a window installed now with two openinings. I have two intertia shock sensors with magnet contacts (REED). I've figured out (from previous threads here, thanks Altor!!) who to wire up each contact, but I can't figure out how to connect them back to the cable coming from the alarm panel. So i have two 4-core cables coming from the window and one 4-core from the alarm and an alarm juntion box ready to join them. I believe I need to join them "in series" but can't seem to get it to work.

Could someone please let me know what cables to join to what???

Thanks in Advance,

Cian

If you have the 2 sensors wired up, then you need to series these.

So if you use the red and black for alarm on the sensors, you will have 2 red and 2 black at the junction box.

Join the 2 black together and connect the 2 red to the cable back to the panel.

Same with if you have tampered using different colours.
