The High Sensitivity Smoke Detector (7351) is a special purpose high sensitivity intelligent addressable photoelectric point detector for applications requiring sensitivity settings over and above the performance of standard photoelectric smoke detectors.

It is designed for very early warning fire detection, and is suitable for protecting valuable assets and operational systems that must remain functioning at all times.

The 7351 achieves detection levels up to approximately 100 times more sensitive than a standard photoelectric detector.

This detector features a smoke sensing chamber designed to detect smoke and diminish stray internal reflections that can cause nuisance alarms.

A suitably configured fire panel will display the location of any detector which has initiated an alarm, fault, or maintenance signal.

Features

• Each detector is individually identifiable on the fire panel display
• Intelligent addressable (IA) communication with fire panel
• Very early warning fire detection capability
• Automatic drift compensation
• Stable communication with excellent noise immunity
• Fire panel may be configured with separate alarm, fault, and maintenance thresholds for each individual detector
• Rotary address switches for setting the address on the intelligent addressable SLC
• Fire panel identifies active detectors by lighting up two red LEDs on the detector housing
• LEDs briefly light up (“blink”) when the detector is polled
• LED blink may be disabled via the fire panel configuration
• Dual LEDs for visibility from all normal viewing angles
• Optional remote LED indicator available
• Magnet test function activates detector and bypasses inbuilt delays to facilitate testing
• Compatible with B300-6 and other System Sensor intelligent addressable bases
• Compatible bases provide an optional anti-tamper feature that prevents removal of the detector without a tool
• UL  listed for open air protection and duct applications (0.5 %/ft to 2 % /ft obscuration)
• UL listed for special applications (0.02 %/ft to 0.5 %/ft obs.)
