Operation: Unsetting the System
When the Accounts Manager returns to open the building and enters his code on
the Keypad, the UNSET option presents the following 3 sub-menus:
ALL AREAS: unsets all areas assigned to the accounts worker (Common Area,
Accounts) and any additional area assigned to the accounts worker. In this case
there are no additional areas. NOTE: The accounts worker cannot UNSET the
Sales area.
COMMON: unsets ONLY the Common Area (Reception). This provides the
option to unarm the reception area only while leaving the Accounts and Sales
offices set.
ACCOUNTS: unsets the Accounts area and the Common Area (Reception). In
this case the Sales area remains set while access is still permitted through the
front door.
Use of Common Areas:
Keyarm Zone
If the entry/exit route in the common area is programmed as a Keyarm zone, when
it is activated all areas in the Common area are SET. Deactivating the keyarm
zone UNSETs all areas in the Common Areas.
Multiple Keypads
If areas assigned to the common area have their own Keypads for entry/exit, it is
important that the exit times associated with those areas provide sufficient time to
allow the user to reach the common area exit. This is in case the area being armed
is the last un-armed area on the system and therefore will trigger arming of the
entire common area.
NOTE
As a rule it is advisable to use common areas in installations that have only one Keypad located at the
common access point, i.e. front door access to the entire building.
