Failure to Communicate
The panel detects that no battery is pres-
ent, that the battery is shorted, or that the
battery is below the low battery threshold
(less than 7.2V
DC).
NOTE: This trouble condition will clear
once the panel determines that the low
battery restore threshold (7.6 VDC) has
been reached.
Communications with the wireless
receiver have failed causing a Hardware
fault, an Aux Supply Trouble is present
or the LCD display is not functioning.
Cover tamper tripped.
The system has detected the presence of
an RF jam for 20 seconds or communica-
tions with the wireless receiver have
failed causing a Hardware fault. An RF
jam may also be detected by a wireless
repeater.
The Trouble light on the alarm panel
glows orange to indicate RF jam.
No AC at panel AC input terminals,
enrolled WS4920/8920 repeater has
experienced loss of AC power.
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.
Press [1] to determine specific trouble
NOTE: If battery is new, allow 24 Hrs. to charge.
• Verify voltage measured across AC terminals is 16-18 VAC.
• Verify voltage measured across battery terminals is 12.5V +/-
0.1V.
• Replace transformer if required.
• Disconnect then reconnect battery leads.
• If Low Battery Trouble LED is still on after 10 minutes,
replace battery.
• Check event buffer to determine specific trouble.
• If buffer logs "Hardware Fault" or "LCD Loss" replace
panel.
• If necessary, test AC outlet for loss of power and remedy.
• Verify that tamper button is installed into backplate.
• Verify that keypad (cover) is secured to backplate.
• Check Event buffer to determine specific trouble.
• If Buffer logs RF Jam trouble, check for external 433MHZ
signal sources. To disable RF Jam: enable Option [7] in pro-
gram section [804] subsection [90].
• If Buffer logs Hardware fault - replace panel.
• Verify voltage measured across AC terminals is 16-
18VAC. Replace transformer if required.
• If buffer logs "Repeater AC Loss", inspect repeater for
cause (power supply unplugged from AC outlet, power sup-
ply wires loose or disconnected.
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 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 cor-
rectly 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].
Alternate Communicator
• Refer to the Communicator installation manual for trouble-
shooting actions.
