Honeywell sixct wireless door slash window contact for lyric con

The Honeywell SiXCT is a wireless door and window contact designed for use with the Resideo Lyric Security Panel. This sensor consists of a larger sensor and a smaller magnet. The sensor is mounted on the door or window frame, while the magnet is mounted on the door or window itself. For best results, the magnet should be within three-quarters of an inch of the sensor when the door or window is closed. Preferably, they should be in direct contact.

Opening the door or window will cause the magnet to become separated from the sensor. This will release a metal reed switch inside the sensor. The sensor will respond by sending out a wireless transmission to the panel. This will let the security system know that the door or window has been opened. The wireless transmissions are sent using 128-bit AES encryption for added wireless security.

Like all wireless sensors, the Honeywell SiXCT requires a battery for power. This is necessary for sending out the wireless signals necessary for communicating with the panel. The action of the contact itself is purely mechanical, and battery power is only needed for reporting activity and status to the panel. This sensor uses a single lithium 3V CR123A battery for power. Resideo recommends using a Duracell DL123A, a Panasonic CR123A or a Honeywell 466 battery with the SiXCT.

When the SiXCT reports to the Lyric Panel, it sends along its current battery level status. A fresh battery will have an operating voltage of 3V. When the voltage drops below 2.3V, the system will report a low-battery trouble for the zone. The user should make sure to replace the battery as soon as possible to prevent loss of RF supervision. To change the battery, slide the front cover away from the back of the device, and pull the housing apart. Carefully remove the old battery, and install a new one in its place. Make sure the polarity for the battery is aligned properly. Then reapply the front cover. For more information, please refer to the Install Guide.
