Trouble
Trouble [2] AC Failure
Trouble [3] Telephone Line Trouble
Trouble [4] Failure to Communicate
Trouble [5] Zone Fault
Cause
No AC at panel AC input
terminals
Phone Line Voltage at TIP, RING on main
panel less than 3VDC
Panel fails to communicate one or more
events to central station
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
An open circuit is present on PGM2 being
used as a 2-wire smoke detector input
One or more wireless devices have not
checked in within the programmed time
A short circuit is present on one or more
zones with double end-of-line resistors
enabled
Troubleshooting
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-31 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 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]
• 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.
• 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.
• 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
• 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.
