Electrical Connections

The flame detector has eight connection terminals as show in Fig 5. Removing the front cover of the
flame detector accesses the connections. The cable is passed through the gland holes in the base of the
detector. Note – When the IFD-E is used on a Conventional system a Fire Resistor will be required
across the FLAME relay, the value of this resistor will be dependent on Control Panel, check with
