Whether connected to the control unit or independent, the indoor siren warns you in the case of an intruder, water damage, gas leaks, or mains power cuts. The outdoor sirens are triggered in the case of a break-in or tampering. Visibly placed on an outside wall, the outdoor alarm will act as a deterrent to potential house-breakers and when triggered, will warn neighbours and make intruders leave the scene because of the loud noise it generates. The alarm siren thus allows an efficient response to domestic incidents or break-ins to offer optimum protection of your family and your assets. Long lasting and easy to install, our wireless sirens have a battery life of 10 years.
