Meet IFC and NFPA code compliance (see Product Features). Individual sensors are quickly and securely attached to each battery and connected in series from the main unit. Each thermal sensor is sealed to IP68 (water, gas and dust proof) and the provided special gel-filled connectors are also sealed against acid ingress, dust, and gases. The alarm relays are 'fail-safe', meaning the user will always get an indication of supply failure. In the event of one or more sensors detecting critical temperature, or a break in the sensor circuit, the monitor warning relay activates and the warning LED on the monitor is illuminated. Simultaneously an LED flashes on the sensor attached to the over-temperature battery, indicating the source of the fault. Should more than 4 cells exceed critical temperature, the system critical alarm relay activates warning of a serious situation at the battery as a whole. • IFC 2015 - 608.3 - Thermal Runaway • NFpA 1 - Article 53.3.2 - Thermal Runaway Typical Connection of Sensors from Main Monitor Technical Specifications Ordering Information • BTM Monitor • BTM Sensors Materials • 12V AC Wall Adapter • Support Literature 1) Model number varies per number of cells (e.g. BTM-60C for system with 60 cells)
