TX500 WIRELESS PIR DETECTOR
installation & operating instructions
INTRODUCTION
HOW THE TX500 WORKS
The TX500 is a battery operated PIR detector with a built in radio transmitter.
Each time the TX500 detects movement it transmits a coded signal to a receiver which then gives an
appropriate output to either operate lighting or interface with an alarm system.
TYPES OF RECEIVERS
RXB. Plug in wireless bleeper. May be plugged into any mains socket in the house or workshop
to give audible indication that the TX500 has detected movement.
RX300. Mains powered receiver to directly operate lighting up to 1000 watts.
RX400. 12 volt receiver to interface with alarm equipment or lighting controllers.
RX16
DC. Multi channel receiver for general alarm applications and more specifically CCTV interface.
The outputs connect directly to multiplexers and matrix switchers.
BATTERY LIFE
Because the TX500 has a very low power consumption when idle (typically 15 micro amps) it means that the
battery will last for a long time. The battery life will depend upon the amount of activations but it is usual for
a standard alkaline battery to last about eighteen months. Where the TX500 is to operate many times a day
it is recommended that a lithium battery be used which has a much higher capacity.
BEGINNING THE INSTALLATION
There are two important considerations to remember when positioning the TX500.
Firstly there should be minimum obstruction between the TX500 and the wireless receiver. Any obstruction
such as trees and especially buildings will reduce the radio transmission range.
Secondly the TX500 should be positioned for best detection and minimum false activations. Fit the
detector at the correct height and avoid reflective surfaces such as windows, water, cars etc. Fix the TX500
to the wall using 4 x No6 x3/4” countersunk screws.
CONTROL BOARD SETTINGS
The PIR sensitivity, Light sensor setting and RF power output are factory SET. You can adjust them
by pulling the board forward.
The SENSITIVITY adjuster can be turned anti-clockwise by degrees to reduce the PIR range and sensitivity
of the detector.
The LIGHT SENSOR adjuster can be switched On or OFF with FUNCTION switch number 4. Only switch
OFF the light sensor when the TX500 is required to operate day and night.
The RF POWER setting should not be increased as this would necessitate a licence.

SITE CODES
A site code is like a key and lock.
The TX500 site code is the key and the receiver site code is the lock.
The receiver code must be the same as the TX500 code. Make a
combination with the site code switches, E.G. 12&3 ON, 4&5 OFF. Put the
same code on the receiver. Any amount of TX500’s can work with a

UNIT CODES
A unit code is the detectors individual identifying code. This code can be
used to identify the detector but only when using an RX16 multi zone
receiver or an RX400 receiver fitted with a PC20 two zone splitter module.

In most other cases the unit code switches are left OFF.

FUNCTION SWITCHES
1. Test ON permanent transmit. OFF Normal
2. Sleep time ON 5 second sleep OFF 30 second sleep
3. Pulse count ON single pulse OFF double pulse
4. Light sensor ON light sensor ON OFF light sensor OFF
Switch (1) transmits a permanent RF signal to test the
transmission range.
Use switch (2) to give a short sleep time for CCTV
applications and for testing purposes. Long sleep times

RADIO SIGNAL
The TX500 has a short 228mm aerial which should be screwed on to the rear of the detector. Try to obtain
line of sight between the TX500 and the receiver. Any object in the path will reduce the range, especially
metal clad barns or other metal constructions.
The receiver should be as high as possible and not hidden away in a ground floor cupboard. Try to put the
receiver in a loft and place the aerial vertically.
TESTING and COMMISSIONING
Insert a PP3 battery into the battery compartment as shown in Fig1 and clip on the battery connector. Be
careful to dress the wires so that they do not get trapped by the front cover and observe the battery polarity.
Set the FUNCTION switches as follows:
Set switch no 1 to OFF.
Set switch no 2 to ON. This will make the detector re-activate after only 5 seconds sleep time and make
walk testing much easier.
Set switch no 3 to ON for single pulse detection or OFF for double pulse detection. If you want to detect
vehicles then the single pulse is better. Double pulse filters out potential false alarms.
Set switch 4 to OFF. This will allow the detector to operate during daylight.
WALK TEST the detector by walking into the detection area and observing the positions where the detector
activates. If you posses an EX6 walk test sounder, plug this into the Jack socket on the control board. This
will make walk testing much easier especially when testing the long range (40 metre) versions.
The RX6 can also be plugged onto an RX16 receiver (if used) and this will not only test the detection area
but also the radio transmission from the detector to the receiver. RXB wireless plug in bleepers are also
useful for walk testing these detectors.
If an RX6 bleeper is not available then the receiver will have to provide the detection information by
observing the lighting or sounders that the receiver operates.
TRANSMISSION TEST.
Test the transmission range by putting function switch no 1 ON (permanent transmit) and observing the
signal LED on the receiver.
LED ON fully. Good signal. LED flashing occasionally. Reasonable signal. LED flashes with long
pauses. Poor signal.
Do not leave switch 1 ON. This is only to test the transmission range and must be switched OFF
again after the test.
To improve reception re-position the TX500 and/or the receiver or use high gain aerials. Contact out
technical help- line.
When testing is complete, switch ON function switch no 4. The TX500 will now only operate at night. If
the detector is to work 24 hours a day, then leave switch 4 OFF.
Switch OFF no 2 unless the detector is operating CCTV or audible warning in which case leave it ON.
