Installation and Maintenance Instructions
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.
