95
General 2 connector, a small jumper wire will be installed between the
+12VDC terminal and the common terminal. This allows the mantrap bypass
terminal to generate a reference voltage that can be sensed when the
terminal is shorted to ground.
If a wet contact is to be used, the small jumper wire would be installed
between the common terminal and the ground terminal on the General 2
connector. Also, a bond wire from the external power supplies ground
terminal will need to be placed in the Ground terminal as well to provide for
ground bonding.
RS232 TX
The T-DAR Series reads data in from external sources or outputs data from
the vision system via a RS422 serial connections found on the Phoenix I/O
Connectors.
Use the specific section of this user’s guide for application details
on available inputs, outputs and configuration of this port.
Input 4 and 6
These are door contacts used to monitor the status of the door position
switches (open or closed). Inputs 4 and 6 monitor the public and secure doors,
respectively. This should be a dedicated switch, and normally requires the
installation of a double pole/double throw door position switch.
When using double doors on the public side, door position switches should be
used on each door. Connect these switches in series so that when either door
opens, relay 4 will be triggered. The same is true for the secure side.
Input 3 and 5
The valid access grant switches must be electrically isolated from the access
control system to allow for proper operation. This will typically require the
installation of a double pole/double throw relay that controls the lock and also
provides an output to the T-DAR system. It should be noted that it is
acceptable for the T-DAR to receive the signal before the door is unlocked,
but not after. Failure to use isolated circuits or using access control system
auxiliary outputs/relays to simulate the valid access switch activity may result
in poor system performance. There can be no noticeable latency in the
receipt of valid access grant switch signals by T-DAR.
The valid access grant switch will connect to the Portal Digital Input terminal
and to either ground or +12v (or applicable source voltage) dependent upon
installation type.
