How Do I Default a Honeywell SiXCT?

You can default a Honeywell SiXCT by opening the sensor's cover, removing the battery, holding the tamper switch down and then reinstalling the battery while the tamper switch is held down. This will reset the device to factory defaults so that it is not paired with a Lyric system.

Defaulting a SiXCT is necessary if the sensor has been enrolled with a panel, but the installer does not have access to that panel to delete the sensor and intends to use the sensor with a different panel. Since the SiXCT is an advanced sensor that uses 128-bit AES encryption, it can only be enrolled with one system at any given time. By defaulting a SiXCT, the sensor's memory can be reset so that it thinks it is not paired with an alarm system. That way, the sensor can be paired with a different Honeywell Lyric Controller System. The option to default the sensor is only available for 24 hours after the SiXCT has been paired with a system. Once 24 hours has elapsed the only way to unpair a SiXCT from the Lyric Security System is through panel programming.

A good way to check whether or not a SiXCT Sensor is paired with an alarm system is to check its green LED light after the device has been faulted or tampered. A slow blink indicates that the device is currently paired with a system. A fast blinking light indicates that it is not paired.

If you need to default a SiXCT Contact, complete the following steps:

1. Open the sensor. Slide the top portion of the sensor up and away from the back cover to open the SiXCT.

2. Remove the battery. The SiXCT is powered using a CR123A battery. This battery is also known as a camera battery, and it is slightly shorter and fatter than a double AA battery. Take the battery out from the sensor.

3. Hold down the tamper. Press and hold the tamper switch for the SiXCT. The tamper switch can be seen in the following picture:

4. Default the sensor: With the tamper switch held down, reapply the CR123A battery to provide power to the sensor. If the tamper switch is held down while the sensor is powered on, the device will be restored to default settings. It can then be paired with a new system. The back cover for the sensor can then be reapplied.
