Failure to Communicate
Cause
PC520X Aux Power Supply Trouble
Panel does not communicate with mod-
ule(s) on KEYBUS
Keypad assigned to incorrect slot
PC520X battery less than 11.5VDC
Note: This trouble condition will not
clear until the battery voltage is
12.5VDC min., under load.
No AC at PC5204 AC inputs
No AC at panel AC input terminals.
Phone line voltage at TIP, RING on main
panel is less than 3V
DC.
Panel fails to communicate one or more
events to central station.
Troubleshooting
• Ensure that a the power supply aux power terminal is
not shorted to ground.
• Ensure that the maximum power supply aux current has
not been exceeded.
connected to KEYBUS (PC5200, PC5204, PC5208,
PC5601).
Modules are immediately enrolled and supervised when
detected on the KEYBUS. If a module has been removed, or
if the slot assignment of a keypad has been changed, module
supervision must be reset.
• View the event buffer (via DLS or LCD5500 keypad) to
identify the specific modules in trouble.
• To reset module supervision:
-Enter Programming Section [902].
-Press [#] (wait 1 minute for panel to scan KEYBUS).
• Enter Programming Section [903] to identify modules
connected to the KEYBUS.
See [1] Low Battery above.
Verify voltage measured across AC terminals is 16-18VAC.
Replace transformer if required.
• Verify voltage measured across AC terminals is 16-
18VAC. Replace transformer if required.
Measure the voltage across TIP and RING on the panel:
• No phone off-hook – 50VDC (approx.)
• Any phone off-hook – 5VDC (approx.)
Wire incoming line directly to TIP and RING.
• If trouble clears, check wiring or the RJ-31x phone jack.
Connect a handset to TIP and RING of the control panel.
Monitor for the following conditions:
Continuous dial tone
• Reverse TIP and RING.
Recorded operator message comes on
• Verify correct phone number is programmed.
• Dial the number programmed using a regular telephone
to determine if a [9] must be dialed or if 800 service is
blocked.
Panel does not respond to handshakes
• Verify the format programmed is supported by the cen-
tral station.
Panel transmits data multiple times without receiving a
handshake
• Verify that the account number and reporting codes are
correctly programmed.
Contact ID and Pulse formats
• Program a HEX [A] to transmit a digit [0].
SIA format
• Program a digit [0] to transmit a digit [0].
