Silent Call Medallion Smoke Detector & Receiver Kit (SD4-MC & MR-1110M)
Once the Silent Call wireless, battery operated smoke detector is activated, it will send a signal (within 200 ft) to the Medallion receiver. The ‘fire’ icon will light up on the receiver to indicate that the ‘fire’ transmitter was activated. There are two reliable alerting options, choose one or both, whichever suits you best: bright, flashing strobe light on the receiver & vibrating a powerful bed shaker (sold separately), connects to the receiver. Safety first, even during a power outage! The battery back-up activates both the strobe light & bed-shaker for up to 24 hours after power outage.
