 Monitored security alarms help deter burglars, discourage employee theft, and ensure employee safety. Composed of a series of devices that detect unauthorized entry, a monitored security alarm sends a signal to a central monitoring station when an intruder is detected.
- Control panels. This is the power source of the entire security system. Typically, the control panel is hidden from plain sight - located in the roof or server closet - and is connected to all other security alarm components including an existing Plain Old Telephone System (POTS).
- Security keypads. These are installed outside the main entrance and allow employees to get in and out of the office. A digital display notes whether the security alarm is armed or disarmed. If equipped with a dual-communication (two-way) system, people at the central monitoring station can talk directly through this device to check if a person who has tripped the alarm is authorized to be there. Additional panels can be set up and installed in other locations throughout the company for a fee (up to $100 per extra keypad).
- Motion detectors. Also known as passive infrared (PIR) detectors, these devices trip the alarm by sensing changes in the infrared energy levels when an intruder is in the area.
- Door and window contacts. These magnetic devices are placed along door jams and window frames and trigger the alarm system when opened.
- Glassbreak sensors. The sensors identify the acoustic shock waves of glass breaking and set off the security alarm.
- Sirens. These loud horns can be attached to the inside and outside of the building and may include strobe lights to draw immediate attention to the intrusion.
