2 Wire Alarm Panels
LS400/LS800S Two-Wire Magnetic Contact
The 2 wire magnetic contact can be fitted to either a door or window to alarm in the event of an intruder. It is simple to install and has the advantage of reverse polarity in that the cable cores can be connected into either of the two terminals.
It can be used with both the LS400 and LS800S to form part of a complete intruder alarm installation.
