Trouble Cause Troubleshooting
Trouble [2] AC Failure
No AC at panel AC input
terminals Verify voltage measured across AC terminals is 16-18V AC .
Replace transformer if required.
Trouble [3] Telephone Line Trouble
Phone Line Voltage at TIP, RING on
main panel less than 3V
DC
• Measure the voltage across TIP and RING on the panel:
• No phone off-hook – 50V
DC (approx)
• Any phone off-hook – 5V DC (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 headset 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.
NOTE:
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 con-
nected (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.
