DC
•
Verify voltage measured across AC terminals is
16-18 V
. Replace transformer if required.
AC
•
Disconnect battery wire leads
• Verify battery charging voltage measured across bat-
tery leads = 13.70 - 13.80 V
•
Connect battery, remove AC power
• Verify measured voltage across battery terminals is
12.5V
min.
DC
•
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
•
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
•
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
Verify printer operation (out of paper, paper jam etc.)
Refer to the T-Link TL250/350 Installation Manual for details.
Short tamper terminal to COM terminal on unused modules
connected to KEYBUS (PC5100, PC5108, PC5200,
PC5204, PC5208, PC5320, PC5400, PC5700).
Check for external 433MHZ signal sources
To disable RF Jam: enable Option [7] in program section
[804] subsection [90].
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.
Check for external 433MHZ signal sources
To disable RF Jam: enable Option [7] in program section
[804] subsection [90].
