The BTM-Series is a dependable low-cost scalable solution for
protecting your batteries against over-temperature and thermal
runaway conditions. 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.
