Manual Alarm - Break Glass and Re-settable
The Standard and Weatherproof units are available using two methods of operation, the conventional way by breaking the glass and the re-settable way by use of a plastic element. Please note units can be adapted on site from the break glass to re-settable type by means of a converstion kit. All units have a unique tamperproof clip on front and both types of manual alarm can be tested with a special common key. This key also resets the plastic element unit and releases the front cover for the glass replacement.
