The AS364 is a general purpose electronic sounder for fire alarm applications. It a first-fix base containing all wiring connections and allow for easy removal / placement of the sounder. The AS364 alarm sounder allows faster installation and maintenance thanks to an innovative mounting base. Dispensing with the need for locking screws, these sounders use a deep base version of the TimeSave base 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. The AS364 provide high sound output at a low current, thus reducing power requirements and system cost. The AS364 sounder is supplied with a volume control as standard, allowing final audio adjustments to be made during installation. With a choice of 32 different tones which are switch selectable, the required tone can be selected during installation. A second tone, is available if extra wires are installed in the sounder circuit. The mechanism for locking the sounder to the base, can be activated if required. Once activated, a special tool is required to remove the sounder from the base.
