2.8 Forced Arming 
Forced arming allows you to arm the system even though 
one zone or several zones are disturbed, and the NOT 
READY message is displayed. 
Automatic forced arming only works if the installer allowed 
this option while programming your system. Disturbed 
zones will be bypassed - they will not be armed. The 
protected site will not have maximum protection. 
Note: When forced arming is carried out, the buzzer 
“protests” by emitting a continuous tone during the exit 
delay until the last 10 seconds of the delay. You can 
silence this signal by pressing the arming button again. 
Forced arming “AWAY” proceeds as follows: 
Action Resultant Display Sound 
NOT  READY TO  ARM

2.9 Arming in the Latchkey 
This mode is useful for a parent at work who wants to be 
sure that his children have returned from school and have 
disarmed the system. Arming in the “latchkey” mode 
means that a special “latchkey” message ill be sent out 
when the system is disarmed by a “latchkey user”. 
Latchkey users are holders of user codes 5 through 8 or 
users of Keyfob transmitters 5 through 8. The latchkey 
message is considered an alert and not an alarm, and is 
therefore sent to the private telephones programmed by 
the user as targets for alert messages. 
Latchkey arming is possible only when you arm “AWAY”. 
To arm in the Latchkey mode, proceed as follows: 
Action Resultant Display Sound 
ARMING AWAY
