  • Historically, request-to-exit sensors have not been used in sensitive areas because they are easily compromised. RCR-REX dual technology, however, requires that both PIR and RCR sensors detect intrusion activity to trigger internal relays. For maximum protection, radar can be adjusted so curtains are above floors; objects slipped under doors will not, therefore, activate sensors. Sensors have two detection patterns--infrared PIR and range-controlled radar--that are adjusted independently. Radar range, for example, can be adjusted from three feet to 15 feet (one meter to 4.5 meters) and set to just above the floor if desired.

    Two Form-C output-relay contacts are used to switch door locks and shunt door switches. Flexible RCR-REX lock relays can be set to either fail-safe or fail-secure mode for operation when units are not powered. Users determine lock-relay activation times with easy-to-change DIP-switch settings. Factory default is 1/2 second, but this can be adjusted to one, two, four, eight, 16, 32 or 64 seconds.

    When RCR-REX sounders are turned on, they produce audible tones to warn of door-open-too-long (DOTL) conditions depending on settings. Fifteen seconds before timers close lock-relay contacts, for example, they open monitor-relay contacts to send alarm signals. Closing doors silences sounders, while new movement restarts timers and resets sounders. Beeping tones sound at the end of external input signals if doors are open. Meanwhile, LED indicators turn red for the duration of lock-relay time when motion is detected, flashing twice per second during the 20-second warm-up period. These turn yellow when radar detects motion and green when passive infrared detects motion. Tamper switches identify when housing covers are opened.
