Audible/Visual Commercial Specification Alarm - SAK


Price on Application

This standard alarm system has an ABS plastic enclosure that contains all the controls and protection necessary for the alarm to operate. In addition to a local sounder/strobe there is also a volt free contact for remote monitoring. We offer other remote signalling options such as digital or analogue, wireless or hard wired, please contact us to discuss your specific requirements.

When either the main shower valve or the eyebath valve are activated the flow switch detects the water flow and sends a low voltage signal to the control enclosure, this signal switches on a relay and activates the sounder/strobe.

The alarm sounder automatically switches off after 30 minutes but the strobe will continue to flash and the remote signal will remain ‘ON’ until the alarm condition is removed.

The alarm enclosure will be fitted to an appropriate plate depending on whether it is a shower or eyewash installation.
