Manual Reset:

Occasionally there might be a need to perform a full reset to your SureLock
This is done by Fully unplugging the Power-Supply from AC Outlet and 4Pin Harness
for 20 to 30 seconds…Then you can simply re-connect

At this point you need to Cycle your Garage Door Opener fully two(2) times without
any interruptions !! – We use this to lock in the Current Draw, and timing of you Opener

Mounting Vibration-Sensor on your Garage Door Opener:

Please mount the Vibration-Sensor directly on the Garage Door Openers Metal
Brackets (The same ones used to mount opener to the Ceiling)
SureLock’s Vibration-Sensor should be mounted “ON” or as close to the Openers
Motor as possible

Backup Battery Harness:

Quick Tip: Snip Door Cover to create/allow harness access to enter Battery compartment
and connect to Battery

Continuity Test for SureLock’s main unit:

Start by removing the “White-Wires” from SureLock’s Vibration-Sensor
With your Voltmeter test the Resistance between the two White-Wires

  • We are looking for 3.8 to 4.2 Ohm’s of resistance under normal circumstances

  • If you are seeing a Short – You need to check the full length of the White-Wire for
    any nicks / shorts (This is easily created if a Staple-gun was used during installation)

  • If you are seeing a completely Open circuit, Check to confirm the White-Wires have
    not been severed

If you are unable to find the issue causing you problems, please don’t hesitate to
