Section 4: Access Control

NOTE: This section only applies to systems that have PC4820 Access
Control modules, or PC4850 Telephone Entry modules installed. Talk
to your installer for information regarding the access control
capabilities of your system.

4.1 About Access Card Readers (PC4820 Modules)

To gain access to an area via a door with an access card reader, present
your access card through the reader. Depending on how your card has
been programmed, the system will either grant or deny you access to the
protected area.
Most access card readers will have a status light. This light will indicate
your access status once the card is presented. The light will appear
according to the following conditions:
• Steady red light: The door is locked.
• Steady green light: The door is unlocked.
• Slowly flashing from red to green: The partition is armed.
• Flashing from red to green twice per second: The reader is waiting
for a Privilege card to be swiped.
• Flashing from red to green three times per second: Access is denied.
Some access card readers also have audible indicators which beep under
certain conditions. The reader may beep when an access control door has
been left open too long, or when a door has been forced open.
Arming and Disarming Using an Access Card
You may be able to automatically arm or disarm your partition using
your access card. Ask your installer if this feature has been enabled.
To arm a partition using an access card, ensure that the partition area is
secured. Close all protected doors and cease movement in areas covered
by motion detectors. Swipe the access card in the reader. Push the "Arm"
button. The exit delay will begin.
To disarm a partition, present the access card to the reader. The partition
may disarm if the system allows. If disarming is granted, the door will
unlock. When you open the door, the system will disarm the partition.
A NOTE FOR PROGRAMMING ACCESS CARDS:
To arm or disarm a partition using an access card, the following access
code options must be programmed:
• User Code Options: Arming and Disarming Options
• Edit Partition Mask: Partition access must be granted.
See Section 3 "Access Codes" for instructions on programming these
options.
