Burglar Alarm Control Panel
The control panels available in the market range from small compact type which incorporates a hooter / siren and can accommodate a few different types of Sensors (detectors) to a more advanced type which can perform more complex functions like, automatic dialing to a phone, cellular phone and convey a pre-recorded message informing about intrusion, in addition to or in place of, local audio visual alarm.
Central Control Unit
The advance versions also have the capability of functioning with user codes for arming and disarming and of switching over to built-in power supply in case of power failure. Many control units also use a remote (infra-red or Radio Frequency based) for arming or disarming of the control unit.

ARMING / DISARMING SYSTEM
Arming in a loose sense is switching on the system and disarming is disabling (switching off) the system. These functions can be performed using a simple switch or by using a keypad in which the user is supposed to enter a password.
In advanced systems, this may be done by an (Radio Frequency) RF remote or an Infrared remote. In cost effective systems, this is done using a traditional key that operates an electric switch. Such key-based systems are convenient for use by all age groups and offer more flexibility in terms of increasing number of authorized users. Some of the systems also have a keypad in which the owner is supposed to enter the correct password to do any arming/disarming.
The infrared remote requires that the operator of remote be in visual line of sight of the receiver that is on the control panel, where as the Radio Frequency remote can operate the control panel from anywhere (as long as the receiver is in the range) In addition to arming/disarming the control can support many other functions which may not be available (or even desired) in every control panel.
POWER BACK-UP
All controls should be equipped with sufficient battery standby to operate the system for the maximum duration of outages you are likely to experience in your area. Do remember that the chargeable battery deteriorates with time. The life of a chargeable battery is normally half after one year of usage and requires replacement after 18 months. The amount of batteries needed depends upon the type and amount of devices used and how long you want the system to function without normal electrical power.
ZONES
Zone, in general terms represent an area or collection of sensors that protect an area. Zones allow to pinpoint the area from where the alarm got initiated, otherwise one has to use guess-work & check all doors & windows for intrusion. In large premises, such a feature is very desirable, though it increases the cost. Make sure that your Central Control Panel can be expanded (or has built-in flexibility) to meet your future needs or you may be faced with replacing the control Panel when you want to add devices.
Lets look at a typical zone layout for a control panel so that you can understand the way it is wired and programmed works.
ZONE 1 – (DELAY):
