2.5 Ingress Protection Ratings
The product is rated for ingress Protection as follows:
IP rating per EN60079-0: IP64
IP rating per EN60529: IP66
Type rating per UL50E / NEMA250: 4 / 4X / 13
To maintain the ingress protection rating, the two off cable entries must be fitted with suitably rated, certified cable entry and/or blanking devices during installation.
2.6 Electrical Ratings

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 the max. current draw (tone 1 – 340Hz Continuous).

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 and/or blanking devices during 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.

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.

Access to the Enclosure

Warning – High voltage may be present, risk of electric shock. DO NOT open when energized, disconnect power before opening.
Warning – Hot surfaces. External surfaces and internal components may be hot after operation, take care when handling the equipment.
To access the enclosure, remove the four M4 posy pan head screws, M4 spring and plain washers and withdraw the cover.

To replace cover, check that the ‘O’ ring seal is in place.
Carefully push the cover in place. Insert and tighten down M4 screws, spring and plain washers in the order shown above and tighten down.

Selection of Cable, Cable Glands, Blanking Elements & Adapters

When selecting the cable size, consideration must be given to the input current that each unit draws (see Table 1), the number of sounders on the line and the length of the cable runs. The cable size selected must have the necessary capacity to provide the input current to all of the sounders connected to the line.
The dual entries can be ordered with one of the following options:
2-off M20 x 1.5 thread
2-off ½” NPT thread
1-off M20 x 1.5 & 1-off ½” NPT thread
To maintain the ingress protection rating and mode of protection, the cable entries must be fitted with suitably rated, certified cable entry and/or blanking devices during installation. If conduit is used for installation, seal conduit within 18 inches from the enclosure.
For ambient temperatures over +40ºC the cable entry temperature may exceed +70ºC or the cable branching temperature may exceed +80ºC. Therefore suitable heat resisting cables and cable glands must be used as per table below

If a high IP (Ingress Protection) rating is required then a suitable sealing washer must be fitted under the cable glands or blanking plugs.
For use in explosive dust atmospheres, a minimum ingress protection rating of IP6X must be maintained.
For use in explosive gas atmospheres, a minimum ingress protection rating of IP54 must be maintained.

Cable Connections

Electrical connections are to be made into the terminal blocks on the PCBA located in the enclosure. See section 5 of this manual for access to the enclosure.
Wires having a cross sectional area between 0.5 mm² to 2.5mm² can be connected to each terminal way. If an input and output wire is required the 2-off Live/Neutral or +/- terminals can be used. If fitting 2-off wires to one terminal way the sum of the 2-off wires must be a maximum cross sectional area of 2.5mm². Strip wires to 8mm. Wires may also be fitted using ferrules. Terminal screws need to be tightened down with a tightening torque of 0.45 Nm / 5 Lb-in. When connecting wires to the terminals great care should be taken to dress the wires so that when the cover is inserted into the chamber the wires do not exert excess pressure on the terminal blocks. This is particularly important when using cables with large cross sectional areas such as 2.5mm².

AC Wiring

A 6-way terminal block is provided on the AC Sounder for power. There are 2-off Live, 2-off Neutral and 2-off Earth terminals in total. A 3-way terminal is provided for stage switching with a stage 2, a stage 3 and a common terminal.

DC Wiring

A 10-way terminal block is provided on the DC Sounder.
There are 2-off +ve, 2-off -ve, 2-off stage 2, 2-off stage 3 and 2-off Earth terminals in total.

9.3 Line Monitoring

On E2xS2 DC units, DC reverse line monitoring can be used if required. All DC sounders have a blocking diode fitted in their supply input lines. An end of line monitoring resistor can be connected across the +ve and –ve terminals. If an end of line resistor is used it must have the following values:
24V DC Sounders
Minimum resistance 3K9 Ohms
Minimum resistance 1K Ohms
Minimum Power 0.5W
Minimum Power 2.0W
48V DC Sounders
Minimum resistance 15K Ohms
Minimum resistance 3K9 Ohms
Minimum Power 0.5W
Minimum Power 2.0W
The resistor must be connected directly across the +ve and -ve terminals as shown in the following drawing. Whilst keeping its leads as short as possible, a spacing of at least 1/16” (1.58mm) must be provided through air and over surfaces between uninsulated live parts.

Settings

10.1 Tone Selection
The sounders have 45 different tones that can be selected for the first stage alarm. The sounders can then be switched to sound second and third stage alarm tones. The tones are selected by operation of a DIP switch on the PCB for both DC and AC units. The tone table on page six shows the switch positions for the 45 tones and which tones are available for the second and third stages. To operate the sounder on stage 1 simply connect the supply voltage to the normal supply terminals (+ve and –ve for DC units, L and N for AC units).
10.2 Volume Control
Warning – High noise levels above 85dB(A) during operation. High levels of noise may cause hearing loss, wear suitable ear protection when equipment is in operation.
The output level of the E2x sounder can be set by adjusting the volume control potentiometer (see Fig 4 for AC & Fig 6 for DC). For maximum output, set the potentiometer fully clockwise.

Maintenance, Overhaul & Repair

Maintenance, repair and overhaul of the equipment should only be carried out by suitably qualified personnel in accordance with the current relevant standards:

To avoid a possible ELECTROSTACTIC CHARGE the unit must only be cleaned with a damp cloth.
Units must not be opened while an explosive atmosphere is present.
If opening the unit during maintenance operations a clean environment must be maintained and any dust layer removed prior to opening the unit.
