installer code is at
default
value
"5555"
and
the
DSC
system
is in a normal state, no trouble or
zone
fault conditions
. A soft re
-boot
(hold TEST button for 10 secs
. release)
of radio will access
the DSC panel programming
to extract zone/partition data. This will be viewable on a local DSC
keypad.
The
Radio will take approximately 10 minutes,
it's
LEDs
scrolling
from
top to bottom
while
pull
ing
data from the panel
. Up
on a successful reboot, R355 (restore) event
will be sent
indicating the panel is properly connected to the radio
If the
LTEM
-P fails to get
data from the DSC panel, the fault LED on the radio will flash.
The
radio will need to be re-
booted again.
Prior to
rebooting, check that
the
installer code is set,
and
no
system
troubles
or zone faults
exist,
and system remains in the normal state during syncing
process.

NOTE:
During Syncing process, k
eypads connected to the system will indicate that the system
is busy or that it
's entered programming mode on its own. This busy/programming state can last
for up to
5 or
more minutes depending on the panel. Once the keypads indicate the system is
free, the sync procedure has concluded successfully.

If the startup sequence fails (after 10 minutes), the radio will enter normal LED state,
and a supervision fault report
(CID: E355
, no zone #) will be sent
.

3. DSC System Status –
Common Trouble Conditions

Having any one of these trouble conditions during LTEM
-P boot
up will interfere with
communicator setup, ensure that these conditions are cleared from keypad before
re-booting
communicator.

Alarms

For LTEM
-P to successfully place the panel into programming mode, the user must clear ALL
alarms.
To clear alarm memory, Arm and Disarm the panel. The panel must be Ready to Arm,
no zones
faulted,
and no system trouble conditions are present.

ARMED

For LTEM
-P to successfully place the panel into programming mode, the user must DISARM
the system. Please
have the system ready to arm before rebooting radio.

Menus

For
the LTEM
-P to successfully place the panel into programming mode, the user must NOT be
in a menu. Please leave any menus (press ‘#’ as needed) before rebooting radio.

General System Trouble

Generated by PC5204 (power supply module), and PC5400 (printer module).

For PC5204 tie a 1k resister from terminal O1 to AUX. If Output# 1 is unused, check that the
wires are in good condition by measuring resistance.

General System Tamper

Generated by modules, please check that the tamper on expanders or other modules are not
getting triggered. On zone expanders you can tie a 1k resistor to the tamper terminal and
ground. No way to clear through panel programming.

If installer code, wiring and system status is normal, then do another re
-boot on the radio. It will
collect data and
function normal.

Upon a successful reboot, R355 (restore) event
will be sent indicating the panel is properly
connected to the radi
o and fault LED will be off.
