3. COMPONENTS
4. SETTING-UP PROCEDURES
4.1 Before installing the sensor, it is required to register it with the Ajax security system. In
order to register the sensor, it is necessary to switch the Ajax security system’s receiver to
«Add Device» mode (the receiver’s manual explains how to accomplish it) and to put the
switch «2» (PICTURE 3) on the sensor to the «ON» position. Sensor’s light must blink at the
moment of switching on. The registration request is transmitted at the moment the sensor
is switched on only! In case the registration was not successful, switch off the sensor, wait for
5 seconds and switch it on again. If the sensor’s light blinks constantly (each second during
one minute), it means that the sensor is not registered. The light blinks in the same way if the
sensor is deleted from the registration list. Non-registered sensor blinks also throughout 3
seconds during each activation.
4.2 Having registered the sensor successfully, select an appropriate location to install it.
2. SPECIFICATIONS
ATTENTION!
Make sure that in the installation location sensor has a stable radio contact with
the receiver! A maximum distance of 2000 m (6562 ft) between the sensor and the
central unit is mentioned as a comparison with other devices. This distance was found
as a result of open area tests. Connection quality and distance between the sensor
and the receiver can vary depending on installation location, walls, compartments,
bridgings, as well as the thickness and constructional material. Signal coming through
obstacles, loses power. For example, distance range between the sensor and receiver,
divided with two reinforced concrete bearing walls, constitutes approximately 30 m
(98.4 ft). Please note that moving the sensor alongside the doors even 10 cm (4 in), it is
possible to improve the signal reception considerably.
DoorProtect
Make sure to check the signal strength! It is possible to launch a signal level test on the
receiver’s side. Test launching is described in the receiver’s manual.
ATTENTION!
Signal level test and detection zone test for sensors take some time to start. A certain
period of time is necessary for the receiver to send a test request to the sensor, and for
the sensor to send a test response.
RECEIVER SENSOR'S LIGHT EMITTING DIODE DESCRIPTION

1 indication bar blinks twice per second low signal
0 bars short fl ashes each 1.5 seconds no signal
5. INSTALLATION
5.1 In order to assemble the sensor and the big magnet, lift up the plastic SmartBracket
panel with your fi nger (PICTURE 1), move it alongside the frame and remove it.
In order to assemble the small magnet, take its fastening clip out of the frame lifting it up
with a screwdriver (PICTURE 2).
