ABOUT THIS DOCUMENT
This document provides a brief overview of disabled persons toilet alarm system design and
installation, based on the recommendations of BS8300 (the code of practice for the design
of buildings and their approaches to meet the needs of disabled people).
For further information, please refer to the full version of BS8300, copies of which are
available at your local reference library or can be purchased from the BSI (British Standards
Institute; Tel. +44 (0)20 8996 9000; Web: www.bsi-global.com). Other National standards of
design and installation should be referenced and adhered to where applicable.
This document must not be left accessible to the user. A separate user guide (document no.
DNU9510000) is available for this purpose.
No responsibility can be accepted by the manufacturer or distributors of this equipment for
any misinterpretation of an instruction or guidance note or for the compliance of the system
as a whole.

IMPORTANT NOTES
This equipment must be installed and maintained by a suitably skilled and
technically competent person.

The One Zone Call Controller included in this kit is a piece of Class 2
! equipment. However, any metal parts used during installation (i.e. metal
back box) MUST be earthed. The earth termination point on the One
Zone Call Controller is provided for installer convenience only and, as such, should
only be used if an earth connection is not re q u i red elsewhere.

This product has been manufactured in conformance with the requirements

of all applicable EU Council Directives.

 DESIGNING A SYSTEM
The diagram below shows a typical layout for a good practice disabled persons toilet alarm
system based on the recommendations of BS8300. It should be noted that the exact position
of the devices shown can be varied to suit a particular application provided that the recom-
mendations described are met.
Other/alternative standards of design and installation should be adhered to where pertinent.

Up to three additional 800 Series devices (ceiling pulls, overdoor lights, reset points, etc., can be
connected to the system if re q u i red - see pages 10 & 11 for details). Note that the call con-
t roller also features an onboard volt-free relay which can be optionally interfaced to externally
powered beacons, strobes or other ancillary devices (again, see page 10 for details).

All system components should be sited internally in areas where they are readily accessible
by the person(s) designated to use them. Areas should be clean and dry and the ambient
light and sound levels should allow the status of all device indicators and sounders to be
seen and heard. Any likelihood of tampering or vandalism should also be taken into account.

(standby) plus 15 minutes (alarm running time) in the event of a mains failure.
This will be indicated by the controller’s ‘ON’ LED flashing green approximately once per
second.
Should the mains supply remain disconnected for a prolonged period of time, the battery
backup facility will automatically shutdown to prevent the batteries from deep discharge.
Note that the default setting for Link PLK2 is link not fitted/battery disabled. This is to
conserve battery life and ensure the safety of the controller during storage/transit. Note that
the shorting link required to enable the facility is provided in the kit’s accessory pack.

Optional emergency/distress call level (Extra equipment required)

If required, the call controller can be used to generate an additional, more urgent level of
call using separately available components from our 800 Series Call System range.
Compatible devices include the NC804DE emergency call point and the NC802DEWM water
resistant alert point (see pages 9 & 10 for details). These devices are typically used to allow
the person attending to the call to request additional assistance should the person who
raised the alarm be in distress.
When an emergency/distress call is triggered, an active or muted standard alarm call will be
overridden. The controller’s ‘CALLING’ LED will flash red and its on-board sounder (and
relay) will pulse intermittently. The overdoor light c/w sounder outside the WC will also
pulse to indicate that more urgent assistance is required.
Up to three additional calling devices can be connected to an NC942B call controller. Should
you wish to connect more, consider using an NC941 call controller which is specifically
designed for powering larger single zone call systems. Information on how to connect addi-
tional devices to the system can be found on page 9.

Sounder and LED test facility

Pressing the controller’s RESET button when link PLK1 is fitted in the Reset (a) position will
cause all of the system’s sounders and LEDs (apart from the ceiling pull’s LED) to activate.
When the button is released, the LEDs and sounders will switch off. The same test can be
carried out by pressing the Remote Reset Point’s RESET button.

EXPANDING THE SYSTEM
The diagrams below show how the system can be optionally expanded to suit a particular application.

Connecting additional 800 Series devices to the system

Up to three additional 800 Series devices (any mix) can be connected to the system as shown
below. Should you wish to connect more than three devices, consider using an NC941 call
c o n t roller which is specifically designed for use on more heavily populated single zone systems.
Devices can be wired to the call controller in any order to suit the application.

OTHER 800 SERIES APPLICATIONS
800 Series Call Systems can be used for literally hundreds of applications ranging from simple
one zone installations in disabled persons toilets to multi-zone systems in nursing homes,
hotels, shops, council offices and GP surgeries. In addition to the items included in this kit, a
wide range of additional components are available including multi-zone indicator panels,
wall-mounting call points (in plastic and stainless steel), water resistant alert points, infrared
ceiling receivers, monitoring points and remote sounders. The diagram below shows a small
selection of the devices available - please contact your distributor for further details.

 ADDENDUM TO NC951 INSTRUCTIONS
UPDATE TO BS8300
BS8300 (the code of practice for the design of buildings and their approaches to meet the needs of disabled people) has recently been updated
and includes some new information regarding the design of emergency assistance alarms and the location of devices used in them.
Although the system design information included in our existing instructions is still fundamentally correct and applicable to many accessible
toilet / emergency assistance alarm systems, your attention is drawn to the following with regard to the 2009 edition of BS8300:-
1. The recommended mounting height for reset buttons has changed. The standard now states they should be located with their bottom edge
between 800mm and 1000mm above floor level.
2. The new 2009 standard includes a number of example accessible WC, ‘changing place’ and accessible bedroom layouts that show ceiling
pulls and reset points located in a variety of positions dependent on the application and other sanitary items used (wash basins, baths, etc).
We therefore recommend you refer to the text and diagrams in BS8300 (2009) before designing and/or installing the system.
Other/alternative standards of design and installation should always be adhered to where pertinent.
