Intelligent Detection and Maintenance
The System Sensor 2W-B includes automatic drift compensation, allowing the detector to adjust sensitivity as dust and environmental conditions change. This helps reduce nuisance alarms and ensures long-term reliability.
When used with compatible modules or panels, the detector provides remote maintenance alerts, allowing technicians to quickly identify detectors that require servicing.
The optional SENS-RDR wireless sensitivity reader enables quick sensitivity measurement in percent per foot obscuration, simplifying maintenance and inspection.
Easy Installation
The i3 Series plug-in design allows installers to pre-wire bases before installing detector heads, saving time during installation. The Stop-Drop N Lock™ feature makes attaching the detector fast and secure.
Flexible mounting options include:
• Octagonal back boxes
• Single gang back boxes
• 4 square back boxes
• Direct ceiling mounting
LED Status Indicators
Wide-angle LED indicators provide instant visual status:
• Green LED: Normal standby operation
• Red LED: Alarm condition
• Additional indications: Maintenance required or trouble condition
Advanced Testing Features
When connected to the 2W-MOD2 maintenance module or compatible panels, the EZ Walk loop test feature allows technicians to verify wiring and detector status quickly using LED indicators at each device.
