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
offers more flexibility in terms of increasing number of authorised 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. |
