System Sensor MOD2W 2-wire I3 Smoke Maintenance Module

Product Description

The SYSTEM SENSOR MOD2W is a maintenance module designed for use with 2-wire I3 series smoke detectors. It connects directly to compatible I3 smoke detectors and enables service technicians to perform maintenance testing and sensitivity verification without removing the detector head from the ceiling. The module communicates maintenance status information, helping life-safety technicians identify detectors that require cleaning or service before a nuisance alarm condition develops. Installation and servicing is typically performed by licensed fire alarm technicians or qualified low-voltage contractors.

The MOD2W is used in commercial and institutional fire alarm systems where I3 intelligent sensing technology is deployed. It supports routine maintenance workflows required under NFPA 72 inspection schedules. The module is sold individually and is intended for integration into existing 2-wire detection circuits where I3 series detectors are already installed.

Compatibility

Designed for use with SYSTEM SENSOR 2-wire I3 series smoke detectors. Consult the product data sheet and system documentation to confirm compatibility with the specific detector model and fire alarm control panel in use.

Installation Notes

Installation and maintenance of fire alarm system components must be performed by qualified fire alarm technicians in accordance with NFPA 72 and all applicable local codes. Disable the fire alarm control panel zone or place the panel in test mode before connecting or disconnecting any detection accessories. Do not install this module on detection circuits outside its rated compatibility range, as improper installation may compromise system integrity or trigger supervisory faults.
