Ingress Protection

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

For combustible dust applications, the cable entry device and
blanking elements shall be in type of explosion protection and
shall have an IP 6X rating.

Adapters

The STEx sounder range can be supplied with the following
types of adapters:

M20 to ½” NPT

M20 to ¾” NPT

M20 to M25

It is important to note that stopping plugs cannot be fitted onto
adapters, only directly onto the M20 entries.

Any other adapters used must be suitably rated and ATEX /
IECEx certified adapters.

If the installation is made using conduit, openings must have a
sealing fitting connected as close as practical to the wall of the
enclosure, but in no case more than the size of the conduit or
50mm, whichever is the lesser.

8) Settings

Following illustrations show the different settings available for
STExS1 Alarm Horn Sounders. See schematic diagrams
D190-06-201 for DC units and D190-06-205 for AC units.

8.1. SPL Configuration

See Table 1 for product power supply and Sound Pressure
Levels (SPL).

Configuration for DC Units

Figure 7: DC PCBA SPL Configuration.

Configuration for AC Units

Figure 8: AC PCBA SPL Configuration.

8.2. Stage Switching Polarity (DC Units)

Switching from positive switching (default) to negative
switching - DC Only.

NOTE:

Max supply is 33V DC

–

if higher DC voltage is

required, use Negative switching.

Figure 9: Stage Switching Polarity.

8.3. Wiring into the Sounder and Beacon separately

The sounder PCBA and beacon PCBA are linked as a default
setting. They can be wired in separately by removing the link
wires. See D190-06-201 (DC) and D190-06-205 (AC) for
wiring details.

Beacon Terminal Linked.
