The AS363 alarm sounder allows faster installation and maintenance thanks to an innovative mounting base. Dispensing with the need for locking screws, these sounders use TimeSaver™ bases from the 630 series detectors. Heads are simply locked onto the base with a “twist and click” action, allowing fitting or removal at any time because the base is the only component that needs to be wired. As the cabling requirement is reduced, commissioning time and costs are naturally reduced as well.
