A work order prediction system is described. The work order prediction system analyzes retrieved sensor signal activity records to compare counts of signal activity in defined signal groupings to corresponding predetermined thresholds of sensor signal activity and generates a report based on the comparison when sensor signal activity exceeds the determined threshold values. The predetermined thresholds of sensor signal are determined for each signal grouping by comparing corresponding groupings of service record activity against determined counts of historical sensor signal activity to establish threshold values for each of the groupings and produce a model based on the comparison of the historical sensor signal activity to service activity.

Methods are disclosed that, in some aspects, provide for the determination of alarm events or non-alarm events based on data received from various sensors monitoring one or more entry points of a premises. Non-alarm events may, for example, include a seismic event or a knock event. Determining whether the data received from the various sensors is an alarm or non-alarm event may be based on data received from two or more sensors monitoring two or more entry points of the premises. Further, data related to the non-alarm event that occurred at the premise may be compared to data related to non-alarm events that occurred at other premises and, based on the comparison, one or more authorities may be alerted to the non-alarm event.

A smoke detector includes a tamper indicator that can prevent a cover from at least partially covering a battery location and/or mounting of a detector body to a detector mount if a battery is not located at the battery location of the detector body. The detector mount and/or cover can engage with the detector body by relative rotation about an engagement axis, and the tamper indicator can pivot about a pivot axis that is parallel to the engagement axis and/or move along a linear path. The tamper indicator can prevent engagement of a portion of the detector mount, such as an intermediate component between the detector body and a base of the detector mount, with the detector body. The intermediate component can at least partially cover the battery location when engaged with the detector body. The base of the detector mount can engage with the detector body via the intermediate component.

The present invention provides a device, comprising one or more embedded tamper deterrent and security systems that trigger an alarm if the device is tampered.

A system and method for providing temporary power to an intermittent unit of a fire alarm system device. The intermittent unit is intermittently activated. The fire alarm system device includes a power storage unit for providing temporary power to the intermittent unit and a voltage converter for providing power at a voltage required by the intermittent unit. The fire alarm system device also includes a power control circuit for discharging the power storage unit through the intermittent unit when the intermittent unit first is activated and then switching to enable the voltage converter to power the intermittent unit.

The shielding status of a security system may be determined based on shielding statuses of individual devices in the security system. The shielding status of each individual device in the security system may be determined based on whether it is in a secured state and is properly functioning. The shielding status of the security system may be determined based on equally or unequally weighted shielding statuses of the individual devices. The shielding status of the security system may be transmitted to a mobile device carried by a user who is outside of the monitored environment. The shielding status of the security system may also be transmitted to the security monitoring company, the device vendor, or the homeowner insurance carrier, which may advertise products or services or provide incentives to the user based on the shielding status of the security system.

The present invention relates to an optoelectronic sensor used with light curtains for monitoring a sensing field. The optoelectronic sensor includes at least one optical unit having at least one radiation emitting element and at least one radiation receiving element and a control unit for processing an output signal generated by said radiation receiving element and for generating a defined sensor signal based on the output signal. The optical unit has a diagnostic unit including a monitoring unit operable to monitor at least one parameter indicative of an operational status of the optical unit. The diagnostic unit includes a processing unit operable to generate a communication signal indicative of said operational status, and the diagnostic unit is arranged in a separately housed, detachable plug-in module. The processing unit comprises a wireless communication interface for wirelessly receiving and transmitting communication signals.

A system and method provide for the immediate transmission of a potential alarm to a remote alarm signal escrow site and from the escrow site to a host station in the event where a control panel or an alarm signaling device is tampered with or destroyed by a disablement tactic, e.g., a “crash and smash intrusion.” A system and method may also send an alarm signal during such an attack by using predictive analysis of real-time events.
