Security Keypads are usually placed near a door to let you operate your system. The keypads inform your family as to the status of the system (i.e., armed, disarmed, etc.).
Magnetic Contacts and Glass break sensors protect doors and windows. A magnetic contact consists of two separate units: a magnetically actuated switch and a magnet. Typically, the magnetic is attached to the door and the switch to the door frame. When the door opens, separating the two, the system is triggered. Glass break sensors hear the acoustic shock wave of breaking glass, it then triggers the system.
Sirens (Interior and Exterior) alert your family to emergency conditions by sounding an alarm. Exterior sirens are normally mounted in a steel box and located under the eaves. A strobe light is frequently attached to the steel box. During an alarm the pulsating light attracts attention to the alarm.
Motion Detectors - Passive Infrared (PIR) motion sensor technology provides one of the most reliable and cost effective methods for protecting spaces in the home or office. PIR detectors trip an alarm by sensing changes in infrared energy levels caused when an intruder moves about the protected area. They emit no energy of their own. They merely "see" infrared images.
