The presence of a “Bell Box”, is synonymous with protection, and when activated emits a blue strobe and audible sound of 110dBA alarm. West London Security offers a wide range of sounders and smoke emitters to suit your needs.

External, Self-actuating Sirens

These contain built-in strobe lights and motion detectors. They have a back-up battery in case the wires are cut.

External Loudspeakers

When used with a monitoring service, these can give intruders a verbal warning that they are being watched.

Smoke Emitters

Professional burglars are aware that, even if an alarm goes off, it can be 10 minutes or so before police or security staff arrive. When triggered, a smoke emitter produces a dense cloud of smoke which disorients intruders and makes it impossible to find anything of value. The latest emitters can fill a shop or large office with smoke in under 20 seconds – this equates to a rate of 375cuM per minute.
