Monitor 
Activity 
Enables an input to generate an alarm if the input does not see any activity for a 
period specified by the NAT (Non Activity Time) timer. 
Special 
Logged 
Forces a log entry when the input is opened or closed, even when an alarm does not 
result. May be selected to apply when a system is armed, when disarmed, or always. 
Paired 
Input 
DO NOT USE THIS OPTION 
Confirm 
Group 
If one or more inputs are selected within the same confirm group, all confirmed 
signals will be disabled. If confirm group is selected as ‘00’ the inputs are not part of 
any group. If inputs are allocated to group 99 they will generate an alarm that results 
in an intruder (unconfirmed) signal to an ARC. They will not under any circumstances 
generate a confirmed signal, regardless of which group the input that triggered the 
‘unconfirmed’ alarm is allocated to. 
Any input may be programmed with any combination of these attributes, except where stated. 
5.6.5 Masking Response 
When disarmed, a masking event will generate an audible ‘alert’ that requires response in the normal way. 
There will be NO signal transmitted to the ARC. When armed, a masking event will generate a normal 
‘intrusion’ response including ‘intruder’ or ‘unconfirmed’ output, but will NOT result in a confirmed alarm if 
paired with a normal activation of the same detector. This harmonises with the requirement of EN50131-1 
cause 8.4.5 and the insurer’s preference expressed in BSIA Form 171. 
5.6.6 Automatic Inhibit of Inputs 
Inputs may be automatically inhibited (omitted) at the time of reinstatement at the end of confirmation time. 
The number of times that this takes place is controlled by the ‘Re-Arm Number’ in Change timers.
