2 Wire Alarm Panels
LS400 Two-Wire External Bell Box
The 2 wire external bell box gives out a 110dB alarm in the event of an activation to attract attention and deter any 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.
