The point detection sensor has two gold-plated sensing probes to prevent corrosion resistance and to provide accurate readings. The LT410 constantly monitors points for leaks, internal faults and power failures and warns of any abnormal conditions. Mounting brackets allow for sensor height adjustment and leveling. The LT410 is the ideal solution for sensing leaks under a raised computer floor or air conditioning drip pans. Two independent outputs provide added flexibility with the capacity to signal both a local alarm panel and a remote building management system or external equipment, such as motorized water shut-off valves. The LT410 is also ideally suited for the following: 1-NO Description Liqui-tect 410 Sensor Power requirements 24 VAC 100 mA, 50/60 Hz, 3 VA (max.)
