Horns & Sounders

SenTRI Wall Sounder

SenTRI wall sounders, VADs and combine Sounder VADS. The range offers this industry beating functionality all powered by the loop.


The SenTRI wall sounder VADs incorporate EN54-23 visual alarms and sound in one device. The range offers all variants in a choice of red or white flash with either a standard IP 21 rating or an EP variant meeting IP66. The range offers this industry beating functionality all powered by the loop. The SenTRI Sounder VADs have been designed to assist with compliance to the fire detection and alarm requirements of the Equality Act 2010 (formerly Disability Discrimination Act). As an aid to commissioning, there is the option to use the HandiLink Infrared remote control to adjust the volume in the room without the need for physical or mechanical access to the device. Password access at the control panel is required to enable this feature so it is not possible to make this adjustment accidentally or maliciously.
