2. Introduction
The basic system consists of a Control Unit (which is powered
by AC mains supply) connected by an extra low voltage 2-
wire link to a Pull Cord Unit which is in turn connected to an
Over-Door Unit by another extra low voltage 2-wire link. The
Over-Door Unit is then connected to a Reset Unit by a further
extra low voltage 2-wire link.
When the pull cord, mounted adjacent to the W.C., is pulled,
the red L.E.D. on the Pull Cord Unit is activated until the system
is reset, assuring the disabled person in distress that the
system has been activated. The sounder and the light on the
Over-Door Unit outside the cubicle, are activated intermittently.
At the Reset Unit inside the cubicle, the light and sounder are
activated intermittently and will both be further reassuring the
person in distress. At the Control Unit the alarm light and the
sounder are activated continuously.
Either the Over-Door Unit or the Control Unit will attract the
attention of an appropriate person either directly or indirectly
and that person will note the zone in alarm, press the reset
button at the Control Unit clearing the alarm and then
investigate the toilet cubicle in question.
Note: Reset button at the Control Unit can be disabled by
moving the reset selection switch to the OFF position.
At any time if the difficulty is resolved the person in distress
can clear the alarm by pressing the reset button in the cubicle.
3. Installation
• Important: This system must be installed and maintained by
a suitably qualified person. Connect the Extra Low Voltage
wiring first. Connect Mains wiring last. See mains ratings
in diagram. Mains supply must come from a fused spur and
