!
CAUTION: Equipment hazard. Do not use in potentially
explosive atmospheres. Do not leave unused
wires exposed.
The piezo electronic sounder and signaling strobe are intended to be
connected to the alarm indicating circuit of a UL Listed fire alarm control
panel. Both sounder and strobe are compatible with DC line supervision.
The electronic sounder can be connected to either 12 or 24 VDC panels.
The strobes produce one flash per second (nominal) with continuous
nominal voltage applied.
Note: The strobe cannot operate from coded power supplies, which
produce interrupted power. The strobe must have an uninterrupted
source of power in order to operate correctly.
