LC 1200 Manual The LC 1200 System 1-5
Perimeter Door
A Perimeter Door alarm occurs when the LC
unit is in Perimeter Door mode (see page 1-3 for
more information) and the door is opened
(Magnetic Switch open).
Internal vs. External alarms
The LC unit comes with an internal alarm
sounder (a piezo) and the capability of triggering
external sounders.
When jumper JP2 “Tone Enable” is in place, all
four alarm types (Egress, Tamper, Power Loss
Supervisor, and Perimeter) will be announced
through the LC unit’s internal piezo.
Note: The internal peizo’s volume level is
controlled by potentiometer R32 “Volume
Control” (see page 2-5).
A charged 9-volt Ni-Cad rechargeable battery is
also required for the Power Loss Supervisor
alarm.
In addition to the internal piezo, the LC unit is
capable of triggering external sounders (see
Chapter 8: External Sounders). An external
sounder can be positioned away from the zone at
a remote location (such as a hallway intersection
or nurse station) for alarm notification. Note:
External sounders are not silenced by the
removal of jumper JP2 “Tone Enable”.
The internal piezo and an external sounder can
operate simultaneously and will be silenced by a
Keypad reset.
A Staff Alert Panel (SAP) or Graphic Display
Panel (GDP) is another option for remote alarm
notification (see Chapter 14: Alert Panels).

Egress
An Egress alarm occurs whenever a Tag enters
an LC unit’s Tx Activation Field and contacts
P2-3 and P2-4 of the LC unit are open (usually
interfaced with a Magnetic Switch or PIR).
When an Egress alarm occurs:
1. Go to the alarm location and take
appropriate action to find the cause of
the alarm.
2. After taking appropriate action, you can
clear the alarm by closing the door and
entering a valid code into the zone
Keypad.
Tamper
A Tamper alarm occurs when the LC unit cover
is removed and the Tamper Switch (S1) is
disengaged.
When a Tamper alarm occurs:
1. Go to the alarm location and take
appropriate action to find the cause of
the alarm.
2. To silence the internal piezo buzzer
while you address the alarm, remove the
LC unit cover and jumper JP2 (Tone
Enable).
3. When finished, replace jumper JP2 and
the LC unit cover, then enter a valid
code into the zone Keypad.
