The 4-channel wireless supervised receiver unit(s) shall be Alpha Communications® WR267 or approved equal. Receiver(s) shall use the 315 MHz frequency for signal reception. No physical wiring connections to the transmitter shall be required to receive a call and the device shall include two (2) whip antennas and a mounting bracket. The receiver(s) shall be able to accept signals from up to 32 of the WP267 wireless transmitters. The receiver, upon receipt of a signal from the WP267 shall actuate an internal relay. The relay shall provide a NORMALLY OPEN dry contact. The relay can be globally selected as Normally Closed by an internal jumper. The relay shall be able to be set for Latching, Momentary or Toggle On/Off in the field.
Contractor shall supply the model SS12P (12VDC) power supply, and shall follow manufacturer's instructions and observe all local and national electrical and building codes.
The WR267 incorporates a dual high-sensitivity superheterodyne diversity receiver with two whip antennas. This type of receiver provides superior performance by preventing loss of signal due to multi-path interference.
