Abstract
The alarm system consists of a siren (1) which is driven from an energy source via a relay (2). This relay (2) has normally open contacts (21) and a winding 22). The winding (22) is connected in parallel with a lamp (3). The lamp is also connected to a winking element (4) which is also fed from the supply source. The supply to the siren (1), the winking element (4) from the source being via a switch which is not shown. This switch being located in whatever part of the location to be protected. When the switch is actuated, voltage is immediately applied to the winking element (4). However, no voltage is applied to the sound alarm (1) and the lamp (3) during the change period of the winking element (4).
