Interconnect Icon

Create an Interconnected System with the X-Series Wireless Module

Honeywell X-Series smoke, heat and carbon monoxide (CO) alarms can be wirelessly interconnected to provide increased protection using Honeywell’s wireless plug-in module XW100. This means that all connected devices will sound when one of them detects a fire, giving occupants in other areas of the building time to safely evacuate.

Mounting Icon

Minimal Installation and Maintenance

No wiring is required for installation of Honeywell X-Series alarms. The mounting plate is simply installed with one or two screws and can be placed on walls or ceilings. Once the mounting plate is in position, the alarm simply slides onto it and is automatically activated.

X-Series detectors include batteries that last for the duration of the alarms lifespan. They never need to be replaced, each alarm has a lifespan of up to ten years, and the whole unit is simply replaced once it has expired. The only maintenance required is occasional cleaning to ensure that the alarm is clear of dust or anything else that may obstruct the detector.
