FOCUS 200 PLUS Installation and Setup Guide
Identifying the ACIU in the CCC Transmission
The table below shows the information sent to the CCC for the various trouble conditions for each unit
number:
Unit Number
DA = Tamper, DT = Trouble (battery or strike wiring), DR = Restore
Super-Degraded Mode
If the control unit fails or the ACIU loses communication with the control unit, the ACIU goes into the
Super-Degraded mode, operating on its battery power. In this mode, the reader will recognize only the
last 63 different card/key codes that were granted access. This allows these people to continue to gain
access in the interim until normal operation is restored.
Attempts at access during the Super-Degraded mode, whether they are successful or not, will not be
logged in the History Log.
Troubleshooting
The following table describes access control troubleshooting procedures:
Symptom
Red LED on reader or
keylok does not go on.
10-20
CCC Transmission
0 DA32, DT32, or DR32
1 DA32, DT33, or DR33
2 DA34, DT34, or DR34
3 DASS, DT35, or DRSS
4 DA36, DT36, or DR36
5 DA37, DT37, or DR37
6 DA38, DT38, or DR33
7 DA39, DT39, or DR39
Probable Cause
1 Battery is not fully charged
or is not properly connected
to ACIU.
2 Insufficient power to
reader.
3 Insufficient voltage to
ACIU.
4 Defective ACIU.
5 Wrong reader.
6 Defective reader.
Corrective Action
1 Make sure that battery is fully charged and is properly
connected to ACIU.
2 Check for 5VDC between TB2-1 (-) and TB2-2 (+). If
you are using a Marlok Keylok or Keyreader, key must
be fully inserted in keyway for this measurement.
A. If reading is too low, either RS-485 bus voltage to
ACIU is too low or ACIU is defective.
B. If reading is OK, problem is in reader or wiring to
reader.
3 Check for at least 12.5VDC across TB1-1 (-) and TB1-2
(+).
A. If reading is too low, add a local power supply.
B. If reading is zero or if polarity is reversed, check
wiring to TB1.
4 Disconnect all wires from TB2. If voltage between TB2-
1 (-) and TB2-2 (+) is not 5VDC, replace ACIU.
5 Replace reader with one that is rated to operate
between 4.75 and 5.25VDC.
6 Disconnect all reader wires on TB2, except wires TB2-1
(-) and TB2-2 (+). If reader had connection to TB2-6,
momentarily connect this wire to TB2-1. If red LED
does not light, replace reader.
