...vary according to tone, frequency, and sound pressure. Some devices have an alarm with a continuous tone, while others have an alarm with a pulsed or non-continuous tone. The frequency measures the number of events or cycles that occur in a time... Search by Specification | Learn More

Fire alarm control panels (FACP) are systems which receive information from input devices (smoke detectors, heat detectors, etc.), process the information, and trigger an output device such as an audio or visual alarm. Search by Specification | Learn More

Annunciators and graphic display panels disclose the layout and annunciate the status and measurement parameters of industrial processes, security and fire alarms of buildings and manufacturing facilities, power distribution networks, and other Search by Specification | Learn More

...in one minute. Flashing alarms may consist of a single flash of the lamp, double flash, triple flash, quad flash, or more. Visual alarms that do not flash provide a continuous visual output. The alarm may provide built-in synchronization. NFPA... Search by Specification | Learn More

Photoelectric smoke detectors are better at sensing smoky fires, such that of a smoldering mattress. Smoke detectors have audible alarms, visible alarms such as light-emitting diodes (LEDs), or both. They may also have an alarm output to a control... Search by Specification | Learn More

Tower lights, stack lights and machine lights are used for alarm and machine status indication. They can be supplied with audible alarms and be used as flashers or steady light configurations. Search by Specification | Learn More

These detectors, called dual-technology motion detectors, typically contain both passive infrared sensors and an active type of sensor, such as microwave. Dual-technology motion detectors reduce the likelihood of false alarms. These detectors also frequently... Learn More

Heat detectors are fire detection devices that sense heat produced by combustion. Heat detectors can trigger an alarm when they detect rapid temperature rise or reach a preset temperature. Search by Specification | Learn More

...and offer a variety of features. Some gas transmitters include audible or visual alarms, interchangeable probes, on-board data storage, a sampling pump, or a sensor array. Others are intrinsically safe (IS) or designed for use in a hazardous environment... Search by Specification | Learn More

Fire suppression systems are used in conjunction with smoke detectors and fire alarm systems to improve and increase public safety. Learn More

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action. Search by Specification | Learn More

Fire protection services install, maintain and monitor safety equipment such as flame and smoke detectors, sprinkler systems, fire alarms and annunciators. Learn More

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches.
