Introduction The BTM1000 battery safety system consists of a simple thermal unit sensor which attaches to each cell, jar or monobloc in a battery, and a system monitor which has five indicator LEDs and two change-over (SPDT) alarm relay outputs. It is powered by a 12 volt power supply and has no electrical connection to the battery it is monitoring, thus the voltage of the cells or jars are not relevant to the system.
BTM-Series User Manual US IFC608.3 (2010) requires that if a sealed battery (or batteries) operated in a single premises contains a total of 50 gallons or over of acid the proprietor must install measures to prevent thermal runaway. System description The thermal sensors are small, sealed units with two wires for connection to the adjacent sensor and an LED which activates to indicate when the cell is in over-temperature.
BTM-Series User Manual The system monitor must be supplied with a DC 12 volt, 1 Amp supply, connected as indicated below. Number of sensors allowed on a system: Although a large number of sensors may be used in a single circuit (over 100), the number of alarm LEDs which can illuminate in alarm conditions is dictated by the amount of voltage available.

BTM-Series User Manual LEDs (monitor) Open circuit LED on control box illuminates fully on: 1. If power is switched on with an open circuit condition 2. If power is switched on with more than four over-temperatures 3. With the unit operating, if 3 or more over temperature occur within 1 second of the first over-temperature With one over-temperature on one sensor the following will be indicated: 1.
BTM-Series User Manual General information: In the event of one or more Jars exceeding critical temperature, or a break in the sensor circuit, the monitor warning relay activates and the warning LED on the monitor is illuminated; at the same time a bright LED flashes on the sensor attached to the over-temperature battery jar, indicating the source of the fault.
BTM-Series User Manual When both wires are firmly inserted into the connector, making sure that both reach the stop at the far end, the top and bottom of the connector should be compressed by a dedicated compression tool*, or, if this tool is not available, providing care is taken a suitable pair of pliers may be used.
