A firefighter's telephone communication system is provided that includes a polarized telephone station that may be connected to either 3-state (detection of normal, open, or call-in) or 4-state (detection of normal, open, short, or call-in) telephone control panel, without the need to alter the telephone station.

Polarized telephone system for 3-state and 4-state systems

An alarm system sensor topology to reduce susceptibility to configuration errors and component failures includes a sensor configured to differentiate between system status conditions, including electrical power isolation for power polarity independence and for sustained sensor operation during power interruptions. A topological method for reducing fire sensor susceptibility to configuration errors and component failures includes configuring a sensor with capability to operate using electrical input power independent of power polarity, and providing capability to operate at least a part of the sensor circuitry for at least a specified time interval in the absence of applied electrical power.

Alarm system sensor topology apparatus and method

A fire alarm system is provided including a controller having a signaling delay, a plurality of smoke and/or heat detectors, a plurality of audible devices which may include sirens, public announcement devices and the like, and a plurality of visible devices which may include strobes, fluorescent lighting and the like. The system provides a directional path to areas of safety for occupants in harms way.

Fire alarm system with method of building occupant evacuation

A device for monitoring changes in airflow rates through detector dust filters in addition to assessing air for alarm indicators, including smoke, heat, gas, and relative humidity, is provided. A method monitors airflow through the detection device and provides a maintenance indication when the airflow has been reduced due to contamination of the dust filters.

Detector with dust filter and airflow monitor

A single communication apparatus for alarm system control boxes that include the combination of a digital communicator and a remote communicating device. The communicating apparatus transmits status reports and events to a remote location. Remote login is permitted to access the control box through a external port or through the remote communication device.

Modem communicator

A device with a multi-function test feature for assessing or directing multiple sensor functions is provided for monitoring and interrogating air flow through Heating/Ventilation/Air-conditioning (HVAC)-type ducts for changes to ambient conditions such as smoke, heat, gas, and/or relative humidity.

Ambient condition detector with multi-function test

Horn/strobe alarm

A method and apparatus that includes housing in which a speaker and strobe light are located with the speaker linked to an audio alert adjuster and a strobe light linked to a visual alert adjuster. The alert levels of both the speaker and the strobe are shown on the exterior of the housing for ease of inspection. The adjusters are located within or outside the housing. The adjuster located within the housing aid in preventing tampering with the levels.

Method and apparatus for adjusting audible and visual outputs of a mounted alarm device

A device with multiple sensors for detecting multiple alarm conditions coupled to a single control unit provides for monitoring and interrogating air flow through Heating/Ventilation/Air-conditioning (HVAC)-type ducts for changes to ambient conditions such as smoke, heat, gas, and/or relative humidity.

Ambient condition detector with multipe sensors and single control unit

Ambient condition detector

A method and apparatus for activating a fire-alarm pull station. The pull stations includes a non-contact switch located within a housing, a movable actuation device linked to the non-contact switch wherein the device moves between an activation and non-activation position and an actuator protector linked to the non-contact switch to aid in preventing improper activation of the non-contact switch.

Apparatus and method for activating a non-contact switch fire alarm pull station

Wall speaker strobe

An emergency alarm system is provided having a manually operated pull-station that activates the system. The emergency alarm system has a camera that provides image data of the area surrounding the pull-station. The emergency alarm system also has a control panel having an image memory that is operable to provide storage for the image data from the camera.
