Typical uses of A30XZSD and A30XZSL are spaces or rooms that need a fire detector integrated with sounder and visual alarm such as hotel rooms.
The coverage of the set should not be more than the coverage of detector with which it is installed, except purposes or uses justified.
From functionally point of view, the detector is wired according to the criteria of the fire control panel. Regarding the sounder and visual alarm base, it is a conventional sounder wired according to the criteria of the equipment which feed it (Sounder output at fire control panel, MDA1Y, MDA2Y, MYOA, etc).
