The Model D-67 1-Channel Receiver is designed for use in security systems and remote switching functions. Typical applications for the receiver include adding a wireless zone, a panic button, or creating a remote arm/disarm feature for a hardwired alarm panel. Each time a transmitter is triggered with a digital code matching the receiver’s digital code, the receiver’s relay will activate for four seconds.

The 5881ENH RF receiver is designed for use with control panels that support an RF receiver connection via the keypad terminals. The receiver recognizes alarm, status, and keypad control messages from wireless transmitters operating at 345 MHz. One or two individually identified receivers can be employed, depending on the control used.
