Introduction
There are two components to the smoke
detector, a 509 Transmitter built into a
plastic adaptor ring, and the detector body
itself, see Figure 1.

Figure 2. 509 Transmitter
When smoke triggers the detector it sounds
its siren. The microphone in the 509
transmitter detects the sound and causes
the transmitter to send a signal to the 500r+
control unit.
If the battery of the smoke detector is low
then the detector starts giving a series of
short “beeps”. The transmitter also detects
these sounds and sends a low battery signal
to the control unit. The transmitter also
sends a low battery signal if its own batteries
are low. Installation
Connecting Batteries
There are two sets of batteries that need
connecting in order to make the smoke
detector work: the smoke detector’s own
battery, and two 1.5V ‘AAA’ size in the
transmitter.
Follow the instruction leaflet to connect the
smoke detector’s battery.
Insert the two AAA batteries into the
transmitter. Make sure you insert them with
the correct polarity.
Register the Detector
To register the detector with the control unit
see “Programming - Detectors” in the 500r+
Installation and Programming Guide. Make
sure you point the red activity LED on the
transmitter at the Learn sensor on the 500r+.
Trigger the transmitter by pressing the Test
button.
Check Final Location
When siting the smoke detector follow the
recommendations in the instruction leaflet
that accompanies the detector.
Once you have chosen a site for the
detector you should check that the transmit-
ter can communicate successfully with the
control unit. Make sure the control unit is in
programming mode and then:
1) Enter the walk test command (40).
