Set and unset the system 
When to set 
The security system should be set if you are the last person to leave the 
premises (or your area), for example at the end of the day. When set, any 
security device detecting intruders activates an alarm. 
When to part set 
In case you are still on the premises (or in your area) it is possible to perform a 
part set of it. For example, you can secure your garage using part set while you 
remain in the house. Notification to the central station may happen depending on 
system configuration settings. Contact your installer for more information. 
You can use part set for perimeter protection, for example when you secure your 
house at night but stay inside. You can move inside of the house, but if someone 
tries to enter without unset, this triggers an alarm. Notification to the central 
station may be sent depending on system configuration settings. Your installer 
can provide details. 
Depending on the keypad model, you may be prompted to choose an appropriate 
set to part set: 
 
1>Part set 1 
2 Part set 2 
When to unset 
If the area you want to enter is set, you must first unset the alarm system before 
you can enter as otherwise you will trigger an alarm. Depending on system 
configuration you may be able to tell when an area is set because the LED on the 
keypad is lit red. If the armed display is enabled, only the Mains LED will be lit. 
Once a valid code is entered, the system status will be shown. 
In most cases an entry beeper sounds indicating that the system needs to be 
unset or an alarm will occur. 
The time limit to leave the premises once set 
Once you have set the system, you must leave the premises (or area) within a 
pre-set time (“exit time”) as otherwise you will set off the alarm. The manager of 
the system needs to inform everyone about this time limit. 
Normally, you will hear a beeper during the time allowed to leave the building. 
Make sure you know which route to take when leaving the premises.
