the Arm/Disarm mask. To postpone an autoarm, the user
must present their access card (during the autoarm pre-
alert) and activate the device connected to the POST input.
Typically the POST input will be a push button device
mounted next to the access card reader (107cm (42") from
the floor) which is assigned to the partition(s).
The PC4010/4020 will send an Autoarm Abort reporting
code to the monitoring station if the reporting code is
programmed. The autoarm will restart at the end of the
Postpone Arm time (ref # [00020305]) unless the partition
has been manually rearmed. The autoarm may be
postponed as many times as desired.
NOTE
: To postpone an autoarm, the user must be
assigned to the partition(s) being armed, and the user’s
access card must have the disarm attribute enabled.
See your PC4010/4020 Instruction Manual for
information on programming access codes and cards.
ARM Inputs
When enabled, this PC4820 input will allow designated
users to arm the selected partitions on the PC4010/4020.
To arm the partition, the user must first ensure that the
partition area(s) to be armed is secure (close all protected
doors and stop movement in areas covered by motion
detectors). The user should present the access card and
activate the device connected to the ARM input. The exit
delay will begin. Typically the ARM input will be
connected to a push button device and should be
mounted next to the access card reader (107cm (42") from
the floor) which is assigned to the partition(s).
NOTE
: To arm partitions, the user must be assigned to
the partition(s) being armed, and the user’s access card
must have the arm attribute enabled. See your PC4010/
4020 Instruction Manual for information on
programming access codes and cards.
REX Inputs
A Request to Exit device can be used on the inside of the
secured area to provide a method of unlocking the door
without the need for an access card reader on the inside
of the door. When the REX device is tripped, the door
will unlock. This will also allow the door to be opened
without the door being “Forced open.” Request to exit
devices can be of many different types. Be sure to read
the installation sheets provided with each unit for proper
installation for the REX devices.
2.4 Outputs – LED, BUZ and OUT Terminals
LED Outputs
The LED outputs for Out Door 1 and Out Door 2 are used
for controlling the LED on the access card readers. This
allows the PC4820 to provide visual feedback when the
access card is presented to the reader. Connect the wire
from the reader indicated as LED to the LED terminal of
the selected output.
When using this output to switch an external device, the
negative terminal of the device must be connected to the
LED output terminal. The positive terminal of the external
device must be connected to the AUX+ terminal.
BUZ Outputs
The BUZ outputs for Out Door 1 and Out Door 2 are
used for controlling the buzzer of the access card readers.
This will allow the PC4820 to provide audible feedback
to indicate error conditions. Connect the wire indicated
as buzzer to the BUZ terminal of the selected output.
When using this output to switch an external device, the
negative terminal of the device must be connected to the
BUZ output terminal. The positive terminal of the external
device must be connected to the AUX+ terminal.
OUT Outputs
Reserved for future use.
2.5 Door Locking Devices – LK1 & LK2 Terminals
Connect door locks to LK1 and LK2. Each lock output
can provide up to 250mA at 12V
DC
. Always check local
regulations concerning the installation of magnetic
locking devices.
The locking device outputs are controlled according to
the installer programmed parameters for allowing access
to, or unlocking the doors according to schedules. These
door locking device outputs can operate DC-powered
locking devices such as electromechanical strikes and can
be configured to operate in fail-safe or fail-secure modes
(normal or reverse action). The typical maximum DC for
each lock output is 250mA.
WARNING
: According to local regulations, there may
be strict limitations to installing magnetic locks or
other similar locking devices on doors used for exit.
Be sure to check local regulations before installing any
door locking device.
2.6 Access Card Readers
Each PC4820 module can control two access card readers.
These can be installed on one door to control both entry
and exit, or on two separate doors to control access in
one direction only. Using the proper cable, the readers
may be located up to 150 meters (500 feet) from the
PC4820 module. The access card readers should be
mounted 107cm (42") from the floor.
WARNING:
Connecting the Red wire lead (or power
lead) of a 5VDC reader to the 12VDC terminal may
damage the reader. See reader installation procedure
for proper power connection.
Using Two Readers to Control One Door
When using the Two Readers option, the PC4820 can use
both readers to control entry and exit from a single access
control point. Each reader can be programmed to have
its own access levels (allowing the ability to separately
control entry and exit permissions for each door on the
system), and schedules. See section 3.2 “Door Options”
for programming information.
NOTE:
When using the Two Reader option, the Door
2 input must be terminated to any COM terminal.
Access Card / Keypad Readers
Access card readers with integrated keypads may be used
with the PC4820. In order to use this reader type, the
user must first present their access card. The LED on the
reader will flash twice every second to indicate to the
user that the reader is waiting for an access code to be
entered. The user will have 15 seconds to enter their access
code. If the code is entered successfully, the door will be
unlocked. The access code entered must be the correct
