The 2351B detector is an intelligent addressable photoelectric smoke detector, compatible with the Pertronic F220 fire panel.

This detector features a smoke sensing chamber designed to detect smoke and diminish stray internal reflections that can cause nuisance alarms. These features were developed to satisfy stringent nuisance alarm immunity tests defined in UL 268 edition 7.

The smoke level in the sensor chamber is continuously monitored and reported to the fire panel. For each individual 2351B detector, the alarm, trouble, and maintenance thresholds are programmable in the fire panel configuration software.

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

Features:

• Each detector is individually identifiable on the fire panel display
• Intelligent addressable (IA) communication with fire panel
• On-board drift compensation
• Fire panel may be configured with separate alarm, fault, and maintenance thresholds for each individual detector
• Smoke sensitivity configurable in the fire panel
• Rotary address switches for setting the address on the intelligent addressable SLC
• F220 fire panel monitors up to 159 detectors per 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
• UL listed to UL 268 edition 7 for open air protection
• UL 268A listed for duct applications
