General information

The passive infrared sensor GW 10/12/14 861 - GW 10/12/14 866 is an independent device
which is capable of detecting the presence of infrared energy generated by the movement
of a person within the area controlled by the sensor.
The alarm, tamper and surveillance alarms statuses enable the transmission, the low
battery status is automatically queued to the first useful transmission.
The radio signal is coded and only compatible with the GW 20470 and GW 20481 control
units; it is powered by three 1.5V alkaline batteries, that guarantee an autonomy of
years of activity, (see the specifications on page 21), the operative range is 50 metres
in open field.
To identify the remote device, a digital code is transmitted using the frequency foreseen for
low power devices (LPD). The code is generated when the device is installed, a valid
random code using a 34 billion combination system is transmitted; a reception collision-
proof procedure is activated to increase the level of security on the system.
The sensor incorporates the following functions: A sophisticated alarm generation
circuit with coded radio transmission, LED display, an integration system (with option of
two or four impulses in 8 seconds) to eliminate any alarms caused by puntiform and
sudden overheating.
GW 10/12/14 861 - GW 10/12/14 866 is fitted with a 5 minute inhibition timer, between
one alarm and another, to protect the battery charge used in the case of continuous
movement in the protected area.
The internal battery is constantly monitored to detect its charge status and any malfunction
signal will be queued and transmitted with the next useful transmission.
The incorporated indicator LEDs (which can be excluded) signal the operating status of the
sensor.
It is recommended to follow the basic installation instructions for infrared detectors
provided in this manual.
