Chapter 2: The LC1400T 2-4
Reset All & Reset Lock Events
A Reset All event resets all the alarms and
locks/elevator controls of the LC1400T zone.
This allows for a tag to be escorted through
a zone without activating alarms or locks or
deactivating an elevator.
A Reset Lock event only resets the lock at the
LC1400T zone. This allows for staff to move
through a zone while preventing tags from
doing so, as an alarm will still sound when a
door opens if a tag enters, or is already within,
the zone during the event.
During any reset event, a timer determines
how long the reset and its effects stay active
after a code is entered into the keypad. For
Reset All events, this is called the Reset All
Timer. For Reset Lock events, this is called the
Exit Door timer.
When a resident/patient is being
escorted through a monitored exit point
When a staff member is escorting a resident/
patient through a monitored exit point:
• A valid Reset All code is entered into the
keypad (Reset All-In goes high, edge driven).
• The LC1400T drops Lock Trigger (goes high)
to the lock.
• The LC1400T deactivates the Door Alarm
relay, which deactivates the external
sounder.
When resets are congured to terminate
once the door closes
Reset All and Reset Lock are individually
configurable to be terminated by the door
closing during the reset event. When resets are
configured to terminate once the door closes:
• A closing door deactivates the Reset All/
Reset Lock function.
• The LC1400T operates as if the Reset All
timer/Exit Door timer expired.
When Reset All is activated as indenite
Reset All can be activated as indefinite by
keeping Reset All In high when the Reset All
timer expires. When this occurs, the LC1400T:
• Will stay in a Reset All state until it sees a
low signal on Reset All In after a new Reset
All timer expiration.
• The Reset All timer must be re-triggered by a
rising edge on Reset All In.
Resetting an Alarm
To reset an alarm, the staff member uses a
keypad (Reset All In goes high, edge driven)
to reset the LC1400T. When Reset All In goes
high:
• Lock Release Delay timer is reset.
• LC1400T drops Lock Trigger (goes high and
stays high) to the lock (regardless of the
Lock Release Delay Timer value).
• LC1400T drops Reset to Lock (goes low for as
long as the value of the Reset All Timer) to
the lock.
• The LC1400T deactivates the Door Alarm
relay, which deactivates the external
sounder.
