Alto 818 Installation and Operation
3-18 P/N 66109074001 Rev. D
3.9 CONTROLLED DOORS
Early in the development of an installation plan, a list of controlled doors should be prepared. For
each door, the list should specify whether one or both sides of the door will be controlled. Specify
which doors are emergency doors which should be configured to unlock in the event of an
emergency. List the lock type, reader, sensors, keypads and switches to be used.
3.9.1 UNMONITORED DOORS
Although they may have either an outside reader or both an outside and an inside reader, access
controlled doors are said to be unmonitored if they do not have a door switch connected to the
Alto 818. The ACU will not detect when such doors are forced open or left open too long. These
doors will relock only when the unlock time runs out. A monitored door may be changed to
unmonitored by shunting the door switch with the SHUNT command.
3.9.2 DOOR LOCKS
WSE recommends that all controlled devices, including door locks, be rated for continuous
industrial duty. All auto-unlock and reverse action locks must be rated for continuous duty. All
locks must be capable of operating within the full range of the lock power supply.
