2. Clifford & Snell was originally established in 1929 and has a History of pioneering many elec-
tronic systems and devices. In 1967 the company was responsible for the introduction of the
world's first ever electronic sounder. This breakthrough in technology became the foundation
for a long and established role in the manufacture and development of future generations of
product.
The Company offers a comprehensive range, addressing a wide variety of applications and
industry sectors, including Hazardous Area, Industrial and Process Control, through to the Fire
and Security market. The nature of our industry demands quality and reliability at all times and
this is achieved by employing the very latest assembly and manufacturing techniques, within
our UK manufacturing facility.
Our customers require continuous quality of the highest standard and this is achieved through
our BS EN ISO 9001: 2000 Quality Management System, which ensures total control
throughout the entire manufacturing process. Clifford & Snell are committed to maintaining its
product approvals to address the industries needs on a worldwide basis and certification
includes UL, cULus, ATEX, GOST-R, IECEx, EN54-3, VdS and GL.
Areas such as Oil & Gas where Standards & Certification are an
essential part of the design criteria. The Yodalex range of
Explosion Proof Sounders, Strobes and Call Point Stations meet
the necessary industry standards and directives with compliance
to the North American UL, cULus, IECEx, European ATEX, and
for the Russian market, GOST-R, which allows compliance on a
truly global basis.
Industrial & Process Control
Hazardous Area
Industrial & Process Control is an important market and early
indication of a process breakdown, malfunction or overheating is
vital in relation to safety both from the perspective of
safeguarding employees as well as preventing costly equipment
damage and subsequent downtime and loss of productivity. The
Yodalarm sounders and Yodalight sounder/strobes provide an
audible and visual alarm function, with UL, cULus, GL,Vds and
the EN54-3 approval, allowing compatibility with a wide variety
of applications and industries.
Fire & General Signalling
For Fire and General Signalling applications the Yodac range
provides an ideal solution. With sound outputs up to 106dB,
32 international sound tones, AC or DC supply voltages, a
range of lens and strobe options and approvals such as EN54-3,
VdS, UL and cULus, this product offers an ideal signalling
solution across most industry sectors.

surface or bulkhead. A gasket is supplied, should the surface be
uneven, or if the unit is to be used in wet conditions.
The installation is completed by fitting the beacon onto the back box
by means of the supplied screws.

MOUNTING
All units are supplied separate from the back box for ease of
installation. The back box must be mounted with the two cable
entries at the top or bottom. The back box should be mounted to
a reasonably flat surface or to a standard wiring box, using any
of the internal mounting holes. A gasket is supplied, should the
surface be uneven, or if the unit is to be used in wet conditions.
To maintain the integrity of the weather seal, the cable must be
fitted using a suitable sealed gland. The installation is completed
by fitting the beacon onto the back box by means of the supplied
screws.

MOUNTING
All units are supplied separate from the back box for ease of
installation. The back box should be mounted to a reasonably flat
surface or bulkhead. A gasket is supplied, should the surface be
uneven, or if the unit is to be used in wet conditions.
The installation is completed by fitting the beacon onto the back box
by means of the supplied screws.
LINE MONITORING
Monitoring via reverse polarity
End of line resistor: - minimum 3K3 ohms, 0.5 watts wire-wound or
