Bypass/isolation switch

For loads up to 3,000 amps, the 00572TEC bypass/isolation switch from Russelectric reduces the unit’s footprint by 50% in comparison to side-by-side designs. The bypass/isolation switch allows the operator to bypass directly to either the normal or emergency source regardless of the position or condition of the transfer switch.

Fire detector

The advanced multi-criteria fire detector engineered by System Sensor combines a carbon monoxide sensing cell, an infrared sensor, a photoelectric smoke sensor, and a thermal sensor into one. If a fire condition is detected on one sensor, the unit confers with the other three before sending out an alarm. Advanced algorithms are then applied to interpret signals from each sensor to monitor every product of combustion while compensating for changing conditions. #8.
