Great news for Alarm Grid customers! We're excited to introduce the all-new Honeywell Home PROSIXMINI3, a discreet surface-mount contact perfect for blending into any décor. Despite its incredibly small size, .9" H x 1" W x 3.1" D, the PROSIXMINI3 offers reliable and effective protection.

Resideo, a leading provider of security solutions under the Honeywell Home, First Alert, and Resideo brand names, is now offering the PROSIXMINI3. This new, small form factor door and window contact is the latest in the company's ongoing effort to provide reliable and convenient encrypted security solutions.

The PROSIXMINI and PROSIXMINI2* remain available options. The introduction of the PROSIXMINI3 provides an additional choice for discreet protection on doors and windows. When selecting the ideal sensor, think of your specific requirements. If a low-profile design is most important, the PROSIXMINI, with its compact coin-style battery, is likely the best fit. However, if sensor depth is not a concern and a narrow form factor is desired, the PROSIXMINI2 or the new PROSIXMINI3 is more suitable.

As of now, the PROSIXMINI3 is only available in white. While additional color options may become available in the future, customers requiring a different color can easily paint the contact to match their décor. When painting, be sure to use a non-metallic paint to prevent any potential issues with the sensor's operation.

*The PROSIXMINI2 is discontinued upon stock exhaustion.
