Hardwired zone issues
System doesn’t go into alarm when zone is tripped.
• System is disarmed. Arm system and then trip the zone.
• Zone is not learned into panel memory. Enter installer/dealer program
mode —LEARN SENSORS, and learn zone into memory.
• Zone is learned into wrong partition. Delete zone and learn into correct
partition or change the partition in the EDIT SENSORS menu.
• For Hardwire Input Module (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.
• Check that onboard, HIM, and SnapCard zone inputs have a 2 kohm EOL
resistor installed at the last device on the loop in series for NC loops, in
parallel for NO loops.
• Check for zone wire fault—short circuit on NC loops, open circuit on NO
loops.
Wireless sensor zone issues
System doesn’t respond (in sensor test or when armed) when sensor is
tripped.
• Verify that receiver antennas are routed through holes on top of enclosure
and antenna shrouds are installed.
• Check that the wireless sensor batteries are installed.
• Check the sensor batteries for low voltage. Replace batteries if necessary.
• Use an RF Sniffer (60-401) to verify that sensor is transmitting.
• Sensor is not learned into panel memory. Enter installer/dealer program
mode
—LEARN SENSORS, and learn sensor into memory.
• 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.
• 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 condition.
• Check the sensor battery for low voltage. Replace batteries, if necessary.
