Addressable 4 input Model LF-X5221

• The LF-X5221 Addressable 4 Input/output Module is characterized as 4 inputs power limited and 4 outputs volt free relay with additional sounder circuit output.

• The output relay is normally used for overriding equipment such as lift return, door holder, smoke extract fans, air handling unit, auto dialler to fire brigade, BMS and etc.

• Also, the input circuit is used to acknowledge normally open monitor signal from interface equipment then sending communication signal to the control panel, ideally for monitoring sprinkler system, pressure switch, position switch, signal valves and other third-party equipment such as conventional panel.

• In addition, the unit incorporates an intelligent processor that provides automatic monitoring for both open and short circuit of the input signal line.

• All interfaces can be seen on the panel and can be configured on the command builder to create requirement for fire event scenario, as each circuit has its own unique address, this module occupied 9 address.
