alarm monitoring centers Critical System Alarms include:Cooling and heating alarms have detection and monitoring devices that transmit information about your heating and cooling system often directly to a monitoring company. Flood and water alarm systems monitor your plumbing system where even small leaks can go unnoticed and result in thousands of dollars in repairs. Types of Alarm Sensors:Alarm Sensors are essential elements of your home security system. A wide variety of security alarm sensors and detectors are available for use. It is obvious what most sensors do, so we will only describe the main ones used in a basic system. Contact Sensors: Most burglaries involve doors, either on entry or while leaving the house.

Dual Tech motion detectors use two different technologies in the same unit: passive infrared and microwave. These devices are designed to avoid false alarms since both technologies must detect motion before setting off the alarm. Photoelectric Sensors: These sensors project a beam of light across a hall or doorway to detect motion and are triggered when a person passing through interrupts the beam. Glass Break Detectors: Usually mounted near windows to detect the specific high frequency sound of glass being shattered. They are usually installed on a wall opposite or adjacent to the protected glass and are effective within about 15′ to 25′. Smoke and Heat Detectors: Detect smoke and heat.
