Overview

How Your Security System Works

When an intruder enters the building, a detection device is trig-

gered. The device sends a message to the control panel. The

device may have LEDs (lights) that blink.

The control panel responds by sounding the alarm. (Alarm sounds

vary. If your system is programmed for silent alarms, no bells or

sirens sound.) A message is sent to the keypad and, if connected,

to the monitoring station.

The keypad displays a warning message. Personnel at the moni-

toring station confirm the alarm and respond accordingly.

Some alarms can be canceled before the siren sounds and the

monitoring station is notified. See Section 4 for more information.
