Limitless™ WPMM Series Monitor; 2.4 GHz; 5.5 dBi omni antenna (tilt-and swivel design) with remote magnetic mount & 5 ft cable; NPN output; for use in US, Canada, and Mexico Honeywell WPMM Series Wireless Panel-Mount Monitor is designed to receive a wireless signal from a Honeywell Limitless™ device. When the WPMM monitor receives the signal, the monitor provides indication of a wireless device change-of-state via integral LEDs, audible alarm, and the output turning on. Output types include NPN, PNP, or a solid state relay. While the WPMM monitor is designed primarily for a single wireless device, the monitor can accept signals from multiple wireless devices. The monitor will acknowledge when a signal is received, but not necessarily identify which wireless device transmitted the signal. Refer to the WDRR Series (Limitless™ Din-rail receiver) datasheet to learn more about where each specific wireless input signal is identified with the WDRR receiver.
