The Master Blaster is a powerful motor driven siren designed for use as an internal/external supplementary security sounder.
The siren is powered by a 230V AC supply and contains an integral activation relay. It is supplied with either a 12V DC relay for security applications or 24V DC relay for fire.
Designed for surface mounting, the Master Blaster comes pre-wired with 1 metre of cable and has a separate mounting bracket for ease of installation.
Ideal for use where where a higher sound output is required, the Master Blaster can only be used with security system control panels. A version of the Master Blaster is available without a relay - the Super M (part no 18-980047).
