9. Faults and Troubleshooting
9.1 Device Fail / Active Faults
If a device on the Enforcer 32-WE system is not installed correctly or has been lost from the bus, a
device fail will be present. An example of each fault is as follows:
- Failure on the panel = “Control Panel, Wireless Jamming Pnl”
- Keypad address 3 ( 1-3 available) failure = “Device 3, Device Fail Kpd”
- Tag Readers address 2 (1-3 available) failure = “Device 2, Device Fail Trd”
- Remote Input Expanders addresses 0 (0-4 available) = “RIX-00, Device Fail RIX”
- Remote Output Expanders address 0 = “ROX-00, Device Fail ROX”
If a ‘location name’ is entered for a device, the location will be displayed on the keypad instead of the
address, for example instead of “Device 3” the Keypad will display “Entrance Corridor”.
9.2 System Faults and Troubleshooting
9.2.1 Communications Faults
Fault Description Solution
MODEM FAULT The panel is unable to see the Digi
Modem
If the modem not present, ensure that
“Disable Digi” option is set to ‘YES’ and
“DOWNLOAD MODE” is set to ‘NONE’ or
‘RS232’. If present, but not detected, check
Digi Modem cable is connected correctly.
LINE FAULT There is no telephone or GPRS line a)
Make sure to plug the PSTN modem into an
analogue (conventional) telephone line.
b)
Make sure the SIM card is plugged in on
the modem
c)
Make sure the GPRS signal is good enough.
CALL FAIL TO ARC Call to the ARC has failed. NOTE
This is a communication problem,
which is rarely caused by an
equipment fault. Is primarily related
to the ‘hand-shake’ and ‘kiss-off’
frequency set up at the receiver.
Check ALL call details are programmed
correctly. Ensure signalling format is
correctly set for the ARC receiver.
9.2.2 RS485 Bus Problems
Fault Description Solution
DEVICE FAIL xxx
xxx = ROX
xxx = RIX
xxx = Kpd
xxx = Trd
xxx = Pnl
Wired Device on the RS485 bus has
been lost. Each Device is recognised
by its own name such as:
Output expander = ROX
Input expander= RIX
Keypad = Kpd
Reader = Trd
Control panel = Pnl
Identify device.
Check the device is addressed correctly to
match the programming. Check connections
at the device, and the cabling to it. If the
above are correct, re-boot the device,
followed by a re-boot of the End Station.
485/COMMS LOST Displayed on keypad that has not
yet established communications with
the control panel (End Station)
Part of the routine initialisation procedure.
If this persists, check the display at other
keypad(s) to confirm whether the device
failure is at the keypad or complete system
BUS failure. Temporarily install additional
keypad.
Keypad display is
BLANK
Keypad address does not match any
keypad enabled in the panel.
Check the keypad address by pressing and
holding [D] until the security code is
required. Enter 2000 and set the keypad
address. The Enforcer built in keypad
address MUST always be set to [00]. Make
sure that in the “Install Keypads and
Readers” menu in Engineer mode -the
keypad address set up correctly.
