backup for the audible section) and SMK-7109CS (with battery backup for
the audible section) provide both audible (90 dB) and visual (177
Candela strobe light) signaling and must be hardwired into a wall or
ceiling. Hardwired units require having a 110/120 v AC power
line run to the smoke detector. |
