Smoke detectors are designed to sense the products of combustion. Common types include ionization chambers and photoelectric devices

Audible alarms provide an audible indication of a hazardous situation

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

Warning lights provide a visual indication of a hazardous situation.

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

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 operations

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

Fire sprinkler heads deliver a high-pressure flow of water or dry chemicals to a fire. They are usually are heat-activated and part of a larger fire prevention and safety system.

Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.

Opacity sensors and instruments measure the amount of light transmitted through a sample.

Fire, police and military equipment is designed for fire, military, security and police applications.

Perimeter guards are guardrails and security fences as well as safety devices that produce sound waves when a given perimeter is breached.

Nuclear services companies provide tools, engineering and logistics for the proper monitoring, leak testing, handling and disposal of nuclear materials, instruments and equipment.

Mist collectors and fume collectors reduce the amount of mist, aerosols and fumes in the workplace atmosphere.

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.
