1.
Check to make sure siren is not plugged into an outlet controlled by a switch. Move siren to a
nonswitched outlet location and test.
2.
Panel doesn’t have a Power Line Carrier (PLC) card installed. Install PLC card.
3.
Panel is not powered by a power line carrier transformer. Replace existing transformer with a
power line carrier transformer.
4.
Power transformer and sirens are not plugged into outlets on the same electrical phase.
Relocate sirens at different outlets to determine working locations.
5.
Siren is programmed with incorrect partition house code. Clear siren house code by pressing
and holding siren button for 20 seconds. Reprogram with correct partition house code and
retest. See “Installing Supervised Wireless Sirens” (60-736-95) on page 10 for more informa-
tion.
6.
Siren house code is not programmed into panel. Enter program mode and set SWS and parti-
tion house codes.
Supervised Wireless Sirens (continued)
Siren only works part of the time and/or at odd, irregular intervals.
Check that siren and/or panel transformer is not plugged into an outlet shared with a major appli-
ance, television, or computer which may generate noise and degrade the line carrier signal.
Hardwire Zones
System doesn’t go into alarm when zone is tripped.
1.
System is disarmed. Arm system and then trip the zone.
2.
Zone is not learned into panel memory. Enter installer/dealer program mode—
LEARN SENSORS
,
and learn zone into memory.
3.
Zone is learned into wrong partition. Delete zone and learn into correct partition or change the
partition in the
EDIT SENSORS
menu.
4.
For HIM zones, check that the HIM LED is blinking to verify communication with the panel. If
LED is off, check wiring between HIM and panel.
Zone reports trouble condition.
1.
Check that onboard HIM and SnapCard zone inputs have a 2k-ohm EOL resistor installed at
the last device on the loop in series for N/C loops, in parallel for N/O loops.
2.
Check for zone wire fault—short circuit on N/C loops, open circuit on N/O loops.
3.
Make sure all devices on zone are in non-alarm state, then enter disarm command to reset
zone.
Wireless Sensor Zones
System doesn’t respond (in sensor test or when armed) when sensor is tripped.
1.
Verify that receiver antennas are installed and connections are secure.
2.
Check that the wireless sensor battery(s) are installed.
3.
Check the sensor battery(s) for low voltage. Replace battery(s) if necessary.
4.
Use an RF Sniffer (60-401) to verify that sensor is transmitting.
5.
Sensor is not learned into panel memory. Enter installer/dealer program mode—
LEARN SEN-
SORS
, and learn sensor into memory.
6.
Zone is learned into wrong partition. Delete zone and learn into correct partition or change the
partition in the
EDIT SENSORS
menu.
Sensor reports trouble condition.
1.
Sensor tamper switch is tripped—sensor cover is off, not latched securely, or sensor is not
mounted securely. Secure sensor mounting and/or cover, then trip sensor to clear the condi-
tion.
2.
Check the sensor battery for low voltage. Replace batteries, if necessary.
Touchpad indicates
[sensor #] supervisory
and/or
Sensor [sensor #] supervisory
is heard.
1.
Use an RF Sniffer (60-401) to verify that sensor is transmitting. If sensor is not transmitting,
check battery for low or no voltage and replace.
2.
Change mounting position of sensor (from horizontal to vertical or vice versa) and test sensor
several times for consistency.
3.
Sensor signal is not reaching panel/receiver because sensor is too far away. Remove sensor
from mounted location and test from other locations. Mount sensor in area where signal can
reach panel/receiver.
Smoke sensor beeps once every 44 seconds.
Sensor batteries are getting low. Replace batteries.
