Water Leak Detection Alarms
Controller electronics are housed in a robust
cabinet and provide accurate sensing for water
leakage and comprehensive alarm facilities.
The system is ideal for all types of applications
utilising a mixture of sensors on a single control
panel to give optimum flexibility.
All systems have a test facility to enable simple
regular confidence checking of the equipment.
Lockable cabinets constructed in mild steel with
stove enamelled finish for surface mounting.
20mm Knockouts are provided for ease of cable
entry.
Indications of status on each zone, wiring fault
and supply healthy. Mains fail battery back-up
indication where applicable.
The 85dBA pulsed audible alarm has a fully
functional local mute facility.

Sensor Cable
Sensor cable comprises high flexibility conductors
insulated by Helagaine mono-filament braiding.
Cable or tape sensors are suitable for general
protection under false floors, or can be fastened
directly to pipework enabling coverage in ceiling
void areas.
The cables can be connected together, up to
100m, to cater for larger areas.
For each zone a ‘start of line’ and an ‘end of line’
module is required.
Technical Specification
Dimensions: 8mm dia
Sensor Pads
Sensor pads are constructed from glass fibre with
an anti-corrosive nickel plated surface. Pads will
detect a few cc’s of liquid and are either face up
for location under vulnerable points or face down
for a general coverage.
Technical Specification
Dimensions: 115H x 160W mm
Probe Sensors
Probe sensors are the least sensitive and are
often employed as water level sensors. In general
the sensor is enclosed in a protective cover which
also provides a means for fixing and 20mm gland
entry. The probe is designed for vertical mounting
at skirting level though may be mounted in voids
or sumps. A screw allows 16mm height
adjustment after the sensor is installed.

Introduction
The Water Leak detection system is a water
detection alarm designed to be used in situations
where not just flooding but also undue dampness
could cause damage or ultimately become
dangerous.
The system comprises an electronic monitoring
and alarm control panel connected to sensors
located in the area requiring protection and can
be custom made with a variety of types of
detection sensor to suit the characteristics of the
areas to be covered.
This system has been designed for ease of
installation and modern micro-electronics ensure
a high degree of reliability.
Typical Applications
• Computer Rooms, Telecommunications
and Office Areas
• Electrical Plant and Tank Areas
• Valuables, Antiques and Artifacts
• In general, wherever the presence of
water could be a potential problem to
people, equipment, perishable stock,
data/information archives and record
stores, hospital theatres and so on.
There are also sensors for the detection of non-
conductive fluids such as diesel/oil.
