If the zone test shows the letters OL or Open Loop, the zone is open.
Check that all doors and windows in your home are closed. If everything
is closed, there is no visible damage to the wiring or sensors, and the tester
still reads OL, then there is an issue within that zone that needs to be
diagnosed and repaired. If not repaired, this zone can’t be added to the
Retrofit Alarm Kit.
If any of your zones fail the integrity test, we recommend that you hire a
professional alarm installer to repair the zone. Failures can be dicult to
diagnose and may have a variety of causes, including:
• The contact sensor hardware has been damaged.
• The wire is no longer connected to the sensor.
• The wiring inside the wall is broken or disconnected.
The Retrofit Alarm Kit will not work with wired zones that fail an
integrity test. If you cannot repair the wiring for a zone, wireless Ring Alarm
Contact Sensors can be used to secure the doors and windows in that
zone instead.
5. Next, make sure the wires are long enough.
If your wired alarm zones have short wires, you’ll need to lengthen the
wires to reach the Retrofit Alarm Kit using extra lengths of wire and the
wire nuts/connectors.
6. Keep the zones closed.
Make sure all doors and windows within the wired zones are closed before
you start rewiring them.
7. Begin wiring the zones, one at a time.
A. Choose an app zone for the zone wires. For each 2-wire zone, you’ll place
one wire alone in a numbered terminal and one “Common” terminal
labeled “C” on the Retrofit Alarm Kit. Each “C” can have up to two wires in it.
