The Rada Pulse range of electronic products combine to produce a controlled
washroom environment offering a high degree of energy and water conservation. A
single Rada Pulse Control Box controls showering, hand washing and urinal ushing
with up to 10 outlets in any conguration. Each outlet operates via a no touch sensor,
ensuring maximum hygiene in the washroom.
The system is unique in the way that it is programmed remotely, via a hand held
programmer, which is plugged into the control box to set up or adjust the ow settings
of each individual outlet.
INTRODUCTION
1. Rada Pulse Control Box
The core of the system is the Rada Pulse Control Box containing a transformer
and a PCB. One control box can control up to ten outlets in any conguration e.g.
5 showers, 3 washbasins, 1 urinal and 1 W.C.
The Rada Pulse Control Box is designed to interface with Rada Pulse Sensors and
Rada Pulse Solenoid Valves which control the system functions.
Mounted in the Rada Pulse control box is a Printed Circuit Board to:
•Supply power to the remote mounted sensors.
•Operate remote mounted solenoid valves.
•Allow the operating functions to be programmed in through the hand held
programmer (refer to: 'Accessories').
•Provide a signal to allow the operation of auxiliaries via the Rada Pulse Relay
Box (refer to: 'Accessories') to automatically control lighting, extraction and
drainage pumps.
2. Rada Pulse Sensors
General
There are two generic types of no-touch sensors:
1. Active infrared sensors where a transmitted infrared beam of light is reected
back to the sensor by the proximity of a hand.
2. Ceiling Mounted passive infrared sensors where the sensor detects changes
in temperature in the detection area.
DESCRIPTION

The 120 sensor is a short range active sensor, and is designed to be installed within
a shower, W.C or basin area.
The 122 sensor is a long range active sensor, and is designed to be installed within
a urinal area.
All electrical connections are totally sealed, and the system operates at a very safe
low voltage.
The sensor is supplied with 3.0 metres of 2 core cable and is xed to the wall using
two xing screws (supplied). The screws are then concealed for security, by a chrome
plated cover.
Rada Pulse 129 Sensor
The 129 sensor is a short range active sensor, and is designed to be installed within
a shower, W.C or basin area.
All electrical connections are totally sealed, and the system operates at a very safe
low voltage.
The sensor is supplied with 3.0 metres of 2 core cable and is xed to the wall using
two xing screws (supplied). The sensor is housed within a chrome plated solid disc
with a recessed rear foam seal.
Rada Pulse LR Sensor
The LR sensor is a short range active sensor, and is designed to be installed within
a shower, W.C or basin area.
The LR Sensor is a chrome plated vandal resistant sensor designed to be recessed
or built within the wall surface, to allow for extra security.
All electrical connections are totally sealed, and the system operates at a very safe
low voltage.
The sensor is supplied with 3.0 metres of 2 core cable and is xed in the wall using
M6 xing studs (supplied).
2.2 Passive Sensors
Rada Pulse 124/125/126 Ceiling Sensor
The Rada Pulse Ceiling Sensor are passive sensors for the following applications:
Application Sensor Type
Washbasin 124

3. Solenoid Valves
Rada SV1015 (HP) Solenoid Valve (Direct Acting)
A 1/2" servo assisted solenoid valve, made from WRC approved PA66 Reinforced
Fibreglass, tted with 15 mm compression connections. Flat-faced inserts are
supplied for 1/2" BSP union inlet or outlet connections. An isolating ball valve is
tted to the inlet to allow the water supply to be isolated. A ow direction arrow on
the valve facilitates correct installation.

4. Accessories
4.1 Rada Pulse Relay Box
The Rada Pulse Relay Box is designed to be connected to the auxiliary outputs of the
Rada Pulse Control Box. It provides three switched power relays to enable the Pulse
system to be used in conjunction with equipment such as pumps, lights and fans.
All three relay outputs are fuse protected. The Rada Pulse Hand Held Programmer
is required to enable these functions to be used.
4.2 Rada Pulse Hand Held Programmer
The Rada Pulse Hand Held Programmer is required to modify the default settings
within the Rada Pulse Control Box. The programmer has an extendable lead which
plugs into a socket in the top of the Control Box.
The programmer has a two line (alpha numeric) backlit display and push buttons to
allow the user to navigate through the menu choices and set the conguration data.
Parameters such as activation time, delay time and post ush waiting time etc, can
be programmed for each outlet.
The controller is multilingual and the user can select the appropriate language via
the menu system.
4.3 Rada Disable Key Switch
The Rada Disable Key Switch is a key operated isolation switch designed to be used
with the Rada Pulse Control Box. The unit is wired directly to the Pulse Control Box
and disables the system for cleaning and maintenance.
4.4 Rada Pulse Key Switch
The Rada Pulse Key Switch is a key operated isolation switch designed to be used
with the Rada Pulse Control Box. The unit replaces a sensor for the purpose of
manually turning on the system e.g. group showering.
4.5 Rada Mounting Plate 129
The mounting plate is intended to be used when mounting the Rada Pulse 129
sensor onto difcult walls or surfaces, or where extra security screws need to be
used (not supplied).
The mounting plate is a plated brass ring, pre-drilled, to allow secure xing of the
Rada Pulse 129 sensor. The plate is drilled to allow wall installation or xing onto a
junction box, and is supplied with 2 x M5 x 12 mm stainless steel screws, to secure the
Rada Pulse 129 sensor (Wall screws and junction box screws are not supplied).

INSTALLATION
General
The installation and maintenance of Rada Pulse products must be carried out in
accordance with the instructions and information given in this Product Manual, and
must be conducted by designated, qualied and competent personnel.
1. Before commencing installation refer to section: 'Specications'.
2. Care must be taken during installation to prevent any risk of injury or
damage.
3. In accordance with IEE regulations all electrical connections must be undertaken
by a competent person.
Important! Cross bond copper pipework to maintain earth continuity when
nylon housed solenoid valve SV1015 is tted.
4. Isolate mains voltage supply before removing cover.
5. The installations must comply with all current Building and Electrical Regulations
in force, and relevant Guidelines.
6. The products must not be subjected to extremes of moisture or temperature,
unauthorised tampering or wilful abuse.
7. Rada solenoid valves require a 12 V AC electrical supply, provided by the
transformer housed within the Rada Pulse Control Box.
Warning! Do not connect the solenoid valves to mains voltage.
Note! The Rada Pulse system control box can power a maximum of ve SV3022
solenoid valves. These must be controlled by alternate power outputs on the
Pulse system control box, (e.g. channel 1,3,5,7 and 9).
8. The plumbing must comply with the local requirements of the Water Authority
Undertaker.
9. Isolating valves are recommended to allow servicing of the solenoid valve.
These should be plumbed in so no user operation can occur (Note: no other
user operated control should be tted between the solenoid and the outlet
tting.
10. A thermostatic mixing valve should be installed to provide blended water to the
outlets. The mixing valve should be tted with isolating valves, check valves
and lters with a mesh not exceeding 0.3 mm aperture size.
11. Rada Pulse Solenoid Valves must be approved to EN 60730-2-8.
