Grainger Test Magnet

The System Sensor 386R31 is a replacement test magnet for System Sensor smoke detectors and alarms. It is used to test the functioning of System Sensor devices by simulating smoke when held near the unit. This activates the alarm to ensure it is working properly. The magnet attaches to a pole for easy access to ceiling-mounted detectors. It is suitable for testing a variety of System Sensor models including the 2151, 2151T, 2151R, 2151TRA, and 2151RTRA. The 386R31 measures 2.75 inches long and 0.5 inches in diameter. It allows for quick and simple testing of smoke detection devices.
