B.
Mounting.
To comply with the Type 4X and IP66 enclosure requirements, the strobe
light must be mounted in the DOME UP position.
The Model 224XST, 225XST and 225XST-I should be installed per the NFPA
70 & 72, STATE and LOCAL CODES and should only be performed with the approval
of the authority having jurisdiction.
Pipe Mounting.
The Model 224XST, 225XST and 225XST-I can be mounted on 1/2-inch or 20
mm pipe. The conduit run from the device to the splice box shall not be longer than 10
inches. If metric threads are provided, the enclosure bottom will be identified with a
"M20" marking. Mounting hardware and installation details are left to the installer.
To prevent the connection from loosening, tighten the fixture to a MINIMUM
torque of 5 ft.-lbs. (6.8 N m ) after threading in onto the pipe.
C.
Electrical Connections.
To avoid electrical shock hazards, do not connect wires when power is applied.
For four wire models, when installed, all four wires must be terminated.
Failure to terminate both sets of wires (Black/red, or Black/White) will result
in a shock or fire hazard.

The 120 or 230-240 Vac Strobe units are designed to operate on both 50 and
60 Hz electrical power. Special modifications are NOT required for the two
different AC line frequencies.
white, and one green/yellow. To achieve electrical supervision connect one black to the
phase side of the incoming power source and the other black lead to the phase side of
the outgoing power. Then connect one white lead to the common (neutral) side of the
incoming power source and the other white lead to the common (neutral) side of the
outgoing power. Connect the green/yellow lead to earth ground.
