The Single Channel Slave Receiver is part of the Wireless Alert Series. The product works in conjunction with a control panel. If a monitored site is tripped, the STI transmitter sends a wireless signal to the control panel, efficiently alerting of use. There are various installation options for the Single Channel Slave Receiver such as an open/closed garage door, mail delivery, car in the driveway, fence gate, medicine cabinet, indoor or outdoor area, etc. The small sized receiver easily fits into an existing control panel and operates up to 1000 feet (line of sight).
