Appendix D: Troubleshooting Guide
61
Tr ouble Cause Tr o ubl esh oot ing
Trouble [2] AC Failure
No AC at panel AC input
terminals
Verify voltage measured across AC terminals is 16-18VAC. Replace
transformer if required.
Trouble [3] Telephone Line Trouble
Phone Line Voltage at TIP, RING on main
panel less than 3VDC
• 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-31 phone jack.
Trouble [4] Failure to Communicate
Panel fails to communicate one or more
events to central station
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 central 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]
Trouble [5] Zone Fault Press [5] to determine specific zones with a fault trouble
Open circuit is present on one or more
fire zones on the main panel or zone
expander
• Ensure fire zones have a 5.6K resistor (Green, Blue, Red)
connected.
• Remove the wire leads from Z and COM terminals and measure the
resistance of the wire leads.
- An open circuit indicates a break in the wiring or resistor not
connected.
• Connect a 5.6K resistor (Green, Blue, Red) across the Z and COM
terminals. Verify the trouble condition clears.
An open circuit is present on PGM2 being
used as a 2-wire smoke detector input
• Ensure the correct 2.2K end-of-line resistor is connected (Red,
Red, Red).
• Remove the wire leads from PGM2 and AUX+ terminals and
measure the resistance of the wire leads.
- An open circuit indicates a break in the wiring or no resistor
connected.
• Connect a 2.2K resistor (Red, Red, Red) across the PGM2 and
AUX+ terminals. Verify the trouble condition clears.
One or more wireless devices have not
checked in within the programmed time
• If the trouble occurs immediately, a conflict with a hard wired zone
exists:
- The zone being used is already assigned to a PC5108 zone
expander
- The zone being used is assigned as a keypad zone
• Perform a Module Placement Test – Program Section [904] and
verify the wireless device is in a good location.
- If bad test results occur, test the wireless device in another location
- If the wireless device now tests good, the original mounting
location is bad
- If the wireless device continues to give bad test results replace the
wireless device
A short circuit is present on one or more
zones with double end-of-line resistors
enabled
• Remove the wire leads from Z and COM terminals and measure the
resistance of the wire leads.
- A short circuit indicates a short in the wiring.
• Connect a 5.6K resistor (Green, Blue, Red) across the Z and COM
terminals.
- Verify the trouble condition clears.
