Sounders and Strobes
Sounders and Strobes are connected to the Alarm System to indicate the presence of an intruder, fire or an attack.
Internal Sounders are usually placed in a central location which can be heard from anywhere within the building. External Sounders are usually placed in a location which will generate the most noise and are fitted with Strobes which act as both a visual and audible means of signalling.
As well as generating noise, Sounders act as a deterrent against intruders and are used to indicate that the premises' has an alarm installed. For this reason, a dummy Sounder can also be installed in addition to the live Sounder.
