It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the
units.
The input current will vary according to the voltage input level
and the frequency of the tone selected. The current levels
shown above are for the tone resulting in max. current draw
(tone 1 - 340Hz Continuous).

3) Special Conditions of Use

When used for a Group III application, the surface of the
enclosure may store electrostatic charge and become a
source of ignition in applications with a low relative humidity
<~30% relative humidity where the surface is relatively free of
surface contamination such as dirt, dust, or oil.
Guidance on protection against the risk of ignition due to
electrostatic discharge can be found in EN TR50404 and IEC
TR60079-32.
End user shall adhere to the manufacturer's installation and
instruction when performing housekeeping to avoid the
potential for hazardous electrostatic charges during cleaning,
by using a damp cloth.
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated,
certified cable entry
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
Equipment with the flare horn shall not be installed with the
flare higher than horizontal (to avoid accumulation of dust).
The equipment incorporates metal parts isolated from earth,
having capacitance values exceeding the limits permitted in
the standards of certification. Mounting bracket – 10.33pF.

4) Location and Mounting

The location of the sounder should be made with due regard
to the area over which the warning signal must be audible.
They should only be fixed to services that can carry the
weight of the unit.
The E2x sounder should be secured to any flat surface using
the three 7mm fixing holes on the stainless steel U shaped
mounting bracket. See Figure 1. The required angle can be
achieved by loosening the two large bracket screws in the
side of the unit, which allow adjustment of the sounder in
steps of 18°. On completion of the installation the two large
bracket adjustment screws on the side of the unit must be
fully tightened to ensure that the unit cannot move in service.
