B.
Mounting.
The Model 224XSTHI strobes are designed for hearing impaired applications and should
be installed per the NFPA 70 & 72, STATE and LOCAL CODES. Alternate installation locations and/or
orientations should only be performed with the approval of the authority having jurisdiction. Reference
Figure 1 for the light dispersion pattern of the 224XSTHI.
To reduce the risk of fire or explosion, do not install in a hazardous location if the operating
temperature exceeds the ignition temperature of the hazardous atmosphere. Refer to the
product nameplate for operating temperature markings.
The Model 224XSTHI has provisions for mounting to _" N.P.T threaded pipe. The conduit run
from the device to the splice box shall not be larger than 10 inches. Before mounting, ensure that mating
threads are clean.
C.
Electrical Connections.
To avoid electrical shock hazards, do not connect wires when power is applied.
The DC Models Operating Voltage Range Limits are 16 – 33Vdc.
This product was only tested to its rated operating voltage range. It was not tested to 80% and
110% of these limits.
The DC units are polarity sensitive, and MAY BE DAMAGED by incorrect electrical hookup.
When connecting the DC strobe unit to the voltage supply lines, POLARITY MUST BE
OBSERVED. In addition, damage will result if the voltage operating range of the model
is exceeded.
The 224XSTHI units are provided with five leads; two red, two black and one green/yellow. To
achieve electrical supervision, connect one red (+) lead to the positive side of the incoming power source
and the other red (+) lead to the outgoing power source. Then connect one black (-) lead to the negative
side of the incoming power source and the other black (-) lead to the negative side of the outgoing power
source. If required local building codes, connect the earth ground to the grounding screw located in the
mounting hood.
III.
MAINTENANCE.
To prevent receiving an electrical shock, disconnect the fixture from the supply circuit before
opening.
