Wiring

The FX-1500 should be wired to its own AC power source which is uninterrupted.  A battery backup is recommended where AC power may be interrupted.

FX-1500 Gas Detectors will not work without AC power.

All electrical connections are made to a terminal strip located on the power supply card.  The power supply card is located in the remote unit.  To gain access to the terminal strip open the door and remove the yellow control panel by unscrewing 4 thumb screws.  Next remove the 4 short standoffs then remove the upper amplifier card.  Be careful not to pull the amplifier card out of the enclosure too far.  The cards are attached together by a ribbon cable.  Set the amplifier card on top of the enclosure.  the ribbon cable may also be disconnected from the amplifier card.  Be careful not to bend the pins on the connector.

The sensor wires come attached to the sensor input terminals.  The sensor wires may be disconnected from the sensor input terminals only. Do not disconnect the sensor wires from the sensor unit enclosure.  The sensor cable may be shortened or installed in a conduit.  Do not splice the sensor cable because a continuous length of cable must be installed.  The metal conduit must be secured to an earth ground however, do not earth ground the sensor unless instructed by the factory.  Use only 4 conductor, 22 gauge stranded wire only for sensor connections.
