  • Publication number: 20080266121
    Abstract: An emergency notification and directional signaling apparatus includes an alarm remotely mountable from and responsive to an emergency event detector. The remote alarm activates one of supplementary visual, audible and/or voice message alarms which may include a pulsed strobe, and an audible sound, and/or a recorded voice message. A temperature sensor coupled to the remote alarm initiates another notification and signaling event when the ambient temperature proximate the remote alarm reaches a preset threshold. Emergency event detectors and/or mass notification devices may also activate the remote alarms throughout a building or exterior area in the event of an impending storm, tornado, earthquake, hurricane, etc., to provide localized area support and guidance.

  • Patent number: 6133839
    Abstract: A warning apparatus provides an alarm indication of the location of an exit from an enclosure or room in the event of a detected fire as well as the safety of the exit. An alarm housing is located remote from a smoke detector on or in proximity to a surface of the exit. The smoke detector output is an ultrasonic frequency signal generated upon detection of a fire. The ultrasonic signal is detected by a receiver carried by the alarm which activates the alarm. The alarm is in the form of at least one, and preferably both of a visible light and an audible alarm mounted within the alarm housing. A temperature sensor on the alarm housing detects the temperature of the exit surface and deactivates the alarm if the temperature exceeds the predetermined safe temperature. A test circuit is included in the smoke detector or on a separate transmitter which, when activated, transmits an ultrasonic signal to the receiver to test the proper operation of the alarm.
