Audible/Visual external siren/strobe

Audible only systems are not connected to any phone line and therefore they notify an alarm condition by ringing a local sounder.  Often a strobe light will flash too.  Because of the noise polution act we must programme sounders to cut out after 15-minutes, but the strobe light can continue to flash after the sounder has stopped. 

The model we fit is the Novagard 6 external sounder which is designed in a modern low profile shape and offers simple installation.  It comes with a white cover screen-printed in blue and has a matching blue lens.  The electronics inside are encased within a robust inner cover.  It has: 4 selectable LED flashing sequences, a fault output, Selectable sounder tones, twin piezo sounders, SAB/SCB selectable via a link, audible setting confirmation, and there is a cover & Wall-Tamper fitted as standard.
