ABEL Alarm from 1972

Featured Replies

Bought this recently. It's configured as a tenement alarm. So the keyswitch on the side would arm and disarm the bell box. Very very old.

1972 on the battery!

Yeah, it's quite old. I didn't think the bell box design dated back that early. Plus it's plastic coated so I thought maby mid to late 70s
