The Input delay value represents the delay between an input and appropriate 
zone activation. The allowed range is 0 to 255 seconds. 
8.1.4.5 Key box time 
 
The Key box time extends the exit time. Immediately after the exit timer expires, 
the key box timer starts for duration of the defined time. Before this timer expires, 
the zone must be closed. If it is not closed, a full alarm is triggered again even if 
the previous trigger was also an alarm. During operation of the exit timer and key 
box timer, openings and closings are not registered and do not cause an alarm. 
The allowed range is 0 to 99 minutes.

If a zone is inactive for longer than a time programmed in this menu (in days), an 
appropriate inactive days event is activated for zone. 
Allowed range is 0 to 127, 0 disables the timer for the zone. 
Zone inactive day timers can be viewed and reset using “1.2.1.6 Inactive days”
