Dear Visitor,

In April 2022, following some very careful consideration, the director of Calibre Security Systems Ltd, Lackwinder Singh, decided to merge with Abel Alarm Company Limited, a family run firm that employs similar first rate customer care ethos to those that Calibre Security Systems Ltd had previously prided themselves upon.


Abel Alarm is a privately owned company, established in 1965, and with experience in Intruder, Fire, Access, CCTV and their own Communications and Monitoring Centre, all associates of Calibre Security Systems Ltd are expected to benefit from this transfer of business which has resulted in increases in both manpower and technical knowledge.
