If you don’t do this, the relay may wear out quickly due to arcing
across the contacts. Use a diode such as IN4001 and make sure you
connect it so it is
not conducting when the lock is energised .
Door open and door exit control (egress) inputs
Each door open monitoring input should be wired to a switch whose
contacts are shorted when the door is closed.
Each door exit control input should be wired to a normally open
pushbutton switch mounted next to the door on the secure side.
When the input is shorted, the relay is activated for the relay time.
Module Function
DO Door open input - normally shorted to Ø V - open circuit to activate
Ø V Ø V
EG Door exit control input (egress) - short to Ø V to activate
Operating
Board LEDs
The reader module has two amber LEDs, one for each reader, which
indicates the transmit signals to and from the antennas.
When an LED is flashing, it shows that the Controller is polling the
reader. When the module is first installed in the Controller and
switched on, it is not polled and the LEDs are off. For a reader to
start being polled, it must be configured in the Access Configuration
part of the Access Control Software. Use the
Update System List
command in the Hardware Systems part of the Access Control
Software to see what modules are installed and whether they are
configured. When you configure the reader, provided the system is on
line, the necessary commands are downloaded to the Controller
immediately and the reader starts to work. The LED for that reader
flashes.
Reading Head LEDs
The red, green and amber LED outputs from the reader module are
usually connected to the corresponding LEDs on the 280 Reading
Head. For loop antenna systems, the three LEDs can be provided by a
272 Remote Indicator. The 090 Reading Head has red and green
LEDs.
