Alarm Control
K12 can be used for either monostable alarm
by-pass – or bistable intruder alarm control.
What method used is programmable. Factory
setting is monostable function.
Monostable
Monostable function will (beside opening relay)
also activate the alarm by-pass relay when a
code or exit button is used. Maximum time is
opening time + door held warning time. If the
door is closed during this time both relays are
deactivated. Note that this requires that door
monitor contact be connected. See also section
Door Control.
Bistable
Using bistable function allows activating an in-
truder alarm with
Code + B
. Any codes for only
door opening as well as remote opening will be
disabled. Note that the alarm relay will change
immediately.
Deactivation of the alarm is done with
Code +
A
. If the code also should activate the opening
relay a delay of one second is used. It is also
possible to use door monitoring together with
bistable alarm control. See
Door Control
.
