Alarm system receiver supervisor |
摘要 |
A wireless sensor receiver module for an alarm and/or event reporting system having the capability of monitoring the operational integrity of associated wireless receiver circuitry relative to RF sensor transmissions. A receiver module supervisory timer is reset with the receipt of each sensor transmission, whether an event or supervisory transmission. If sensor transmissions are not received within a supervised receiver time period determined as a function of the number of system sensors, the receiver module communicates a receiver failure condition to the system controller. Noise monitoring circuitry separately monitors the transmissions to enhance the confidence in a receiver failure determination or adjust the period of the receiver module supervisory timer.
