1.5 Board Input Descriptions
Gate operator data inputs can only be used with DoorKing vehicular gate operators (see section 1.1). The tracker expansion board receives data
(Terminals 1-5 and 11-14) from the gate operator control board, converts it to wiegand format, and then sends this wiegand data to the access
control system where it is stored in the transaction buffer. The data that is sent from the gate operator control board includes information such as
gate operator cycle count (x100), if an obstruction was hit, if an attempt was made to force the gate, etc. See the back of manual for a complete
listing of all gate operator transactions. In PAMS applications, only one tracker expansion board is required per traffic lane to monitor the gate
operator activity of the slide, swing or overhead gate operator, and the parking gate operator. The tracker expansion board will also monitor the 24
VAC power from the gate operator control board(s). When this power is removed, a “power out” transaction is sent to the access control system.
Gate Operator Data Input
An alarm condition will exist anytime a controlled door is opened without access being granted by the access control system. The request to exit
input (Terminals 18 & 19) allows the door to be opened without activating the tracker expansion board alarm relays, and will not cause the
access system to report a forced condition. The request to exit is typically used at a controlled access point to allow free exit to personnel. A
“Push To Open” button, or a push bar, etc., is connected to the request to exit input on the tracker expansion board. When this input is activated,
the tracker expansion board
output relay
will activate causing the door strike or magnetic lock to release allowing the door to be opened.
Request to Exit Input
The door ajar input (Terminals 8 & 15) monitors the status of a controlled access door through a magnetic (typical) door contact switch. This
input tells the tracker expansion board if the door is not fully closed, and will cause the alarm and auxiliary relays on the tracker expansion
board to activate under certain conditions (see section 3 and section 4). Typically, when the door is closed, the switch contacts are closed;
when the door is open, the switch contacts are open.
Door Ajar Input
The reset alarm input (Terminals 16 & 19) overrides the door ajar input allowing a door to be held open when necessary. When this input is
activated, the tracker expansion board will not activate its alarm or auxiliary relays even if the door ajar input is activated (see section 4).
Reset Alarm Input
The relay input (Terminals 17 & 19) is connected to the Relay 1 or Relay 2 in the access control system that activates when a valid device
code is received by the access control system. For example, when a card reader connected to the wiegand input on the tracker expansion
board reads the card code, it inputs this information to the tracker expansion board, which in turn sends the information to the access control
system. The access control system then makes the decision to grant or deny access. If access is denied, a transaction of the denial is made
and nothing else happens. If access is granted, a transaction of the access grant is made, and the access control system activates the
communication relay. This relay output is connected to the tracker expansion board system communication relay input, which then causes the
tracker expansion board output relay to activate. The output relay activation will then open the controlled door (or gate). If two or more tracker
expansion boards are connected to the access system, only the output relay on the tracker expansion board that sent the data will activate.
The tracker expansion board relay strike time is set via the programming on the tracker expansion board (see section 4).
Communication Relay Input
(Communication Line to Access Control System’s Main Terminal Relay 1 or Relay 2)
Activation and operation of the AUXILIARY (Terminals 21-22) and ALARM (Terminals 23-24) relays is dependent on the programming on the tracker
expansion board (see section 4). Typically, the auxiliary relay is connected to a local alarm (bell, buzzer, light, etc.) and the alarm relay is connected to
the buildings existing alarm system. These relays provide a dry contact only.
uxiliary and Alarm Relays
The
Output Relay
(Terminals 25-26) activates on command from the access control system, or from a request to exit input. The
output relay
releases the door strike (or magnetic lock) to allow entry or exit, or activates a gate operator if the tracker expansion board is used to control a
vehicular gate.
This relay provides a dry contact only.
Output Relay
All data received at the wiegand input terminals and the gate tracker terminals is sent to the access control system in 26, 30, 31-bit wiegand
format from the wiegand output (Terminals 27-28-29).
Communication Data Output
(Communication Line to Access Control System’s Auxiliary Terminal Wiegand 1 or Wiegand 2)
Tracker expansion boards can accept wiegand input data from most devices that output their data in a wiegand format. When using 30 or
31-bit wiegand devices, the system will only recognize facility code 255 and lower. An access control device (a card reader for example) is
connected to the tracker expansion board (Terminals 6-7-8-9). When the tracker expansion board receives the wiegand data from the access
device, it sends the data to the access control system where the decision to grant or deny access is made. At the same time, a report is made
of this activity and is stored in the transaction buffer. Two access control devices may be connected to a single tracker expansion board,
however each device will report the same location in the transaction report when connected in this method and each device will activate the
same door (or gate). This may be preferable in some instances. For example, if a vehicular gate uses both a card reader and an RF receiver for
resident access, each of these devices can be connected in parallel. Each device will activate the gate (door) that the output relay of the tracker
expansion board is connected to, and each device will appear in the transaction report with the name assigned to the tracker expansion board
in the software (“Main Gate”, for example, Refer to the Dual Door Mode ).
