9.2 Checking the Reader
1. With no reader connected, check the voltage between GND and +18V. This should be at least 18V
dc.
2. Reconnect the reader. Check the voltage at the reader. This should be above 10.5V dc. If not, check
the gauge is correct for the cable distance from the controller (see Section 5.2.1.2).
3. Check the reader operation by presenting a key, if the door controller is in Engineering mode (see
Section 7), a 1 or 2 should appear on the display while the key is being read by the reader.
4. If no key is read, disconnect the reader and connect a known working reader and repeat step 3.
5. If the working reader operates correctly, suspect a faulty reader, or wiring between the door controller
and reader. Go to step 8 to check the wiring and reader.
6. If the working reader does not operate, suspect a faulty reader channel on the door controller.
7. Connect the reader to another channel, if the reader now operates, the original channel is faulty.
Arrange for the door controller to be repaired. Go to step 10.
8. Disconnect the suspect reader. Disconnect the reader connector at the door controller. Check the
cable for short circuits between all conductors, and all conductors and ground.
9. If the cable is to the correct gauge and free from short circuits, connect the known working reader in
place of the suspect reader. If this reader operates, the original is faulty. Arrange for a replacement
with your supplier.
10. Repeat for all four (two on a PAC Portico 1200) reader channels.
9.3 Checking the Lock Output
If all the reader channels are shown to operate correctly, you should check the lock outputs. You should
know whether the lock is fail-safe (power is removed to operate the device) or fail-secure (power is
applied to operate the device). You should also know whether the door controller has been set to provide
12V dc or 24V dc. If interlock has been set on a pair of readers, channels 1 and 4 will operate lock output
1, and channels 2 and 3 will operate lock output 2.
1. For each lock output:
• Make sure that the door secure, that is, the door controller display should not indicate that the
door is open.
• Make sure a lock release time has been set, it should be at least 5 seconds to allow
measurements to be reliably made.
• Establish whether lock sharing has been set.
2. Check the voltage at the lock output (L-, L+) on the controller. This should be 12V or 24V if the lock is
fail-safe, or less than 0.5V if it is fail-secure. (The door controllers have solid state lock outputs,
these will not show exactly 0V when off).
3. Operate the lock, operate the Request to Exit switch or short the RTE reader input to GND. The lock
output should operate. Check the voltage at the lock output. This should now show the reverse of the
previous measurement, i.e. less than 0.5V for fail-safe, 12V or 24V for fail-secure. If not, suspect the
lock output to be faulty.
4. Repeat steps 2 and 3 above but this time measure the voltage at the lock. The lock should receive
the minimum voltage required for it to operate (see the lock manufacturer's specifications). If the
voltage is too low at the lock, the lock supply cable gauge may be too small for the distance from the
controller.
5. Disconnect the cable from the lock. Check the cable for short circuits between the conductors, and
between the conductors and ground.
6. Ensure there is a Metal-Oxide Varistor (MOV) fitted across the lock terminals. If large currents are
used (i.e. >1A) use the large MOV supplied with the door controller. If small currents are used (i.e.
<1A) use the small MOV supplied with the reader. Reconnect the lock.
7. Check the current drawn by the lock. This should not exceed 1.0A (12V dc) or 0.5A (24V dc). If it
significantly exceeds the nominal current specified by the manufacturer, the lock may be faulty.
8. If the lock still fails to operate when the door controller is switching the correct voltage, suspect a
