Selecting the Tone for Ex de Models
All effective warning sounders produce loud sounds, which
may cause, in certain situations, permanent hearing loss. Take
appropriate precautions such as hearing protection.
To select the tone for Ex de models:
1.
Unscrew the M3 hex set screw on the side of the housing one
full turn.
2
. Remove the cover from the housing by turning the cover
counter-clockwise. Three 120-degree spaced reliefs are
provided for a 3/8 inch spanner wrench if needed. If the cover
will not unscrew, back out the set screw a few additional turns.
3.
Loosen the captive Phillips screw retaining the driver/printed
circuit board (PCB).
4.
Slide out the PCB and set the tone selector switch to the
desired tone.
5.
Insert the driver/PCB into the enclosure taking care not to
pinch the wiring and fully tighten the PCB captive screw.
6.
Place cover on housing and tighten it by turning it clockwise.
7.
To ensure O-ring compression, the cover must be fully seated
against the housing when the threads are tightened. Turn
the M3 set screw on the side of the housing until the screw
contacts the housing.
