Long Range Receivers

Use these receivers with the companion model transmitters. When the receiver detects a signal from its companion transmitter, it will verify the digital code, activate its output, and trigger the remote device connected to the receiver.

The receiver has full supervision capabilities. If the "status" option is selected, the receiver expects hourly status signals from its transmitter. If the signals are not received, the receiver will indicate trouble by activating its status output after four hours. Contact supervision allows the receiver's output to follow the transmitter's input, staying activated
as long as the transmitter input is activated. Alternately, an "auto-restore" option can be selected in the transmitter, causing a momentary receiver output each time the transmitter input is activated, If the transmitter sends a low battery signal, the receiver's low battery output will activate.

Power for the receiver can come from an external regulated 12 VDC power supply or from a 12-volt battery. The 1 and four channel receivers output provides isolated N/0 and N/C relay contacts capable of switching a maximum of 1 Amp @ 32 VDC. The low battery and status outputs are solid state and are capable of switching up to 50 mA @ 20 VDC to ground. The 16-channel model's outputs are all low current (100mA at 24VDC).

The 7428B antenna is a 3-foot whip antenna is requried for all transmitters. It includes 18 feet oc coax cable, which can be extended if necesary.

Two 8-position dip switches set the unit's system code. This code will be matched to the companion transmitter. There are 65,536 different system codes possible.

The 1 and 4 channel receivers are housed in a rugged weather-resistant metal enclosure with a sturdy SO-239 antenna connector and a water-tight wiring strain relief bushing. Two indicators (power and RF receive) are visible through a window on the case. The 16-channel model is contained in a non-weatherproof metal case. The three displays show the channel number of the last alarm signal received, the transmitter's battery status, and supervision status.
