The Model XR-16 16-Channel Mid-range Receiver is designed for use in various wireless remote control applications. When the Model XR-16 receiver detects a signal from its companion transmitters, it will verify the digital code, activate the correct output channel, and trigger the remote device connected to the receiver.
The XR-16 receiver has full supervision capabilities. If the status option for a channel is selected, the receiver expects hourly status signals from that channel’s transmitter. If these signals cease, the receiver will indicate trouble by activating its status output after four hours. Contact supervision allows the receiver’s outputs to follow the transmitter’s inputs, each output staying activated as long as each transmitter input is activated. Alternately, an auto-restore option can be selected in the transmitter, causing a momentary receiver output each time any transmitter input is activated. If the transmitter sends a low battery signal, the receiver’s low battery output will activate.
Power for the XR-16 receiver can come from an external 12 VDC power supply (Linear Model T-1224DC) or from a 12-volt battery. A diode protects the unit from reverse power polarity. The XR-16 draws about 50 mA standby, and about 350 mA when all outputs are active. The alarm, low battery and status outputs are solid state and are capable of switching up to 100 mA @ 24 VDC to ground (programmable as N/O or N/C). The receiver’s relay can activate with all signals, or just alarm signals. It provides isolated N/O and N/C relay contacts capable of switching a maximum of 1 Amp @ 24VDC.
Two antennas (sold separately) are available for the XR-16. The Model ANT-1A is an 7-inch rubber duck antenna for short range applications (less than 1 mile). The ANT-1 requires a Model CON-180A connector to mate the antenna to the receiver. The Model ANT-2 is a 3-foot whip antenna for use in long range or difficult installations where more range from the XR-16 is required. A common 9-foot 1/4 wave CB whip antenna can also be used with the XR-16 for maximum range.
Two 8-position switches set the unit’s system code. This code must be matched in the XR-16’s transmitters. There are 65,536 different system codes possible. The two 8-position option switches select the status supervision option for each of the 16 channels.
The receiver is housed in a metal enclosure with an SO-239 antenna connector. Three displays are visible through a window on the case. The left two displays show the channel number, the right display shows the condition. The display scrolls through all the channel numbers with a condition. The right decimal point lights when the receiver has power. During reception, the center decimal point lights. Two internal test points are provided for signal strength and audio monitoring.
