CONTROL PANELS, ALARM & DETECTION
Control Panels are essentially the brains that continually monitor and control the fire system.Detectors that are most commonly used are smoke and heat detectors. These detectors can be cross-zoned to help prevent false discharges.Linear heat detection also is available for adverse ambient conditions that may cause other types of detection to be unreliable. This operates by detecting linear temperature changes over the entire length of a hazard.Control Panels are set up to monitor different detection circuits and to operate discharges and alarms as necessary.Control Panels can monitor and control a fire system for a single hazard and “smart” panels can be programmed to monitor and control multiple hazards.Control Panels for fire systems typically communicate with other building alarm systems.
Early warning smoke detection uses a laser calibrated detector which continuously monitors the air in a hazard and looks for very small pre-combustion smoke particles that occur in advance of actual ignition.
Early warning smoke detection even can be used in “dirty” environments. The detector can be calibrated to ignore common particles in the air.
Early warning smoke detection provides several levels of alarm and can be used to notify people and other fire systems of the pending fire.
Chemetron Early Warning Smoke Detection
Flame detection can spot a fire at the very instant that it begins. It does not have to wait for smoke or heat to reach another detector.
Flame detection often is used in areas where there could be a flash fire.
Flame detectors use infra-red and ultraviolet sensors.
Flame detectors can be used to trigger an immediate discharge of a fire system.
Gas Detection is used to identify dangerous fumes and leaks that could be the pre-curser to a fire or an explosion.
Gas Detection often is used in areas where flammable gases are stored, distributed or used.
Pre-Action systems allow a water pipe to remain “dry” unless smoke or heat is detected by the pre-action system.
Pre-Action systems open a valve and load the water pipe when a fire is detected, and then when a sprinkler head opens, due to heat, the discharge will occur.
