Trouble Cause Troubleshooting
Trouble [1] Service Required Press [1] to determine specific trouble
[1] Low Battery Main panel battery less than 11 V DC
NOTE: This trouble condition will not
clear until the battery voltage is
12.5V
DC min., under load.
NOTE: If battery is new allow 1 Hr. for battery to charge.
•
Verify voltage measured across AC terminals is
16-18 V
AC . Replace transformer if required.
• Disconnect battery wire leads
• Verify battery charging voltage measured across bat-
tery leads = 13.70 - 13.80 V DC .
• Connect battery, remove AC power
• Verify measured voltage across battery terminals is
12.5V DC min.
[2] Bell Circuit Bell+, Bell-...Open Circuit • Disconnect Bell-/Bell+ wire leads, measure resistance
of wire leads.
• Open circuit indicates break in wiring or defective
siren/bell
• Jumper Bell+, Bell- with 1K resistor (Brown, Black, Red)
• Verify trouble clears
[3] General System Trouble PC5204 Output#1 Open Circuit • If Output#1 is unused: Ensure that terminals O1, AUX
are jumpered with 1K resistor (Brown, Black, Red)
• If Output #1 is used: Disconnect wire leads from O1,
AUX terminals, measure the resistance of the wire leads
• Open circuit indicates a break in the wiring
PC5204 AUX • Verify voltage measured across AC input terminals is
16-18V
AC .
• Disconnect all connections to PC5204 AUX terminal.
• Verify AUX voltage is 13.70 - 13.80 V
DC .
Printer connected to PC5400 offline Verify printer operation (out of paper, paper jam etc.)
T-Link Network Fault present
T-Link Receiver Trouble present
T-Link Interface Trouble present Refer to the T-Link TL250/350 Installation Manual for details.
[4] General System Tamper Tamper input on module(s) open
circuit Short tamper terminal to COM terminal on unused modules
connected to KEYBUS (PC5100, PC5108, PC5200,
PC5204, PC5208, PC5320, PC5400, PC5700).
Wireless Receiver - excessive noise
detected Check for external 433MHZ signal sources
To disable RF Jam: enable Option [7] in program section
[804] subsection [90].
[5] Module Supervision Panel does not communicate with
module(s) on KEYBUS
Keypad assigned to incorrect slot.
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, mod-
ule supervision must be reset.
•
View the event buffer (via DLS or LCD5500 keypad) to
identify the specific module(s) in trouble
• To reset module supervision:
• Enter Program Section [902].
• Press [#] (wait 1 minute for panel to scan KEYBUS).
• Enter Program Section [903] to identify modules
connected to KEYBUS.
[6] RF Jam Detected Wireless Receiver - excessive noise
detected. Check for external 433MHZ signal sources
To disable RF Jam: enable Option [7] in program section
[804] subsection [90].
[7] PC5204 Low Battery PC5204 battery less than 11.5V DC
NOTE: This trouble condition will not
clear until the battery voltage is
12.5V
DC min., under load.
See [1] Low Battery above
[8] PC5204 AC Failure No AC at PC5204 AC inputs Verify voltage measured across AC terminals is 16-18V AC .
Replace transformer if required.
