2 GREY / GREY PLUS SATEL
The GREY / GREY Plus detector detects motion in the protected area. This manual applies
to the detector with electronics version H.
1. Features
Motion detection with two sensors: passive infrared sensor (PIR) and microwave sensor
(MW).
Adjustable detection sensitivity of both sensors.
Capability of separate sensor testing.
Digital motion detection algorithm.
Digital temperature compensation.
Pet immunity up to 15 kg.
Microwave based anti-mask feature [GREY Plus].
Built-in end-of-line resistors (2EOL: 2 x 1.1 k).
Bi-color LED indicator.
Remote LED enable / disable.
Alarm memory.
Supervision of motion detection system and supply voltage.
Tamper protection against enclosure opening.
2. Description
The alarm output will turn on for 2 seconds when the infrared sensor (PIR) and
the microwave sensor (MW) detect motion within a time period shorter than 5 seconds.
Anti-mask feature [GREY Plus]
Detection by the microwave sensor of an object moving at a distance of 10-20 centimeters
from the detector is interpreted as an attempt to mask the detector and causes the anti-mask
output to turn on for 5 seconds. Objects permeable to microwaves, but isolating the infrared
radiation are not detected by the anti-mask feature.
The anti-mask feature does not meet the EN 50131-2-4 requirements.
Supervision features
In the event of the voltage drop below 9 V (± 5%) for more than 2 seconds or the motion
detection system failure, the detector will signal a trouble. The trouble is indicated by the
alarm output turning on and the LED lighting up red. Signaling will continue as long as the
trouble exists.
LED indicator
The LED indicates:
warm-up –flashing red and green for about 35 seconds;
motion detected by microwave sensor –ON in green for 2 seconds;
motion detected by PIR sensor –ON in green for 2 seconds;
alarm –ON in red for 2 seconds;
alarm memory –flashing red;
trouble –ON in red for entire duration of the trouble.

Enabling the LED by using a jumper
If you put a jumper across the LED pins in ON position, the LED will be enabled, i.e. it will
indicate the events described above (the LED cannot be enabled / disabled remotely). If you
put a jumper across the LED pins in OFF position, the LED will be disabled, i.e. it will only
indicate warm-up and trouble (but the LED can be enabled / disabled remotely).
Remote LED enable / disable
The LED terminal is provided to allow remote LED enable / disable. When the terminal is
connected to common ground, the LED is enabled. When the terminal is disconnected from
common ground, the LED is disabled.
If the detector is used in the INTEGRA / INTEGRA Plus alarm system, you can connect to
the terminal the OC type control panel output programmed e.g. as “Zone test status” or “BI
switch”.
Alarm memory
If the LED is enabled, the detector can signal the alarm memory. The MEM terminal is
provided to allow the alarm memory enable / disable. The alarm memory is enabled, when
the terminal is connected to common ground. The alarm memory is disabled, when the
terminal is disconnected from common ground. If the alarm memory is enabled and an alarm
occurs, the LED will start flashing red. Indication of the alarm memory will continue until the
alarm memory is enabled again (the MEM terminal is connected to common ground).
Disabling the alarm memory will not stop the alarm memory indication.
If the detector is used in the INTEGRA / INTEGRA Plus alarm system, you can connect to
the MEM terminal the OC type control panel output programmed e.g. as “Armed status”.
3. Electronics board
Do not touch the pyroelectric sensor, so as not to soil it.

When setting the sensitivity of the MW sensor, keep in mind that microwaves can
penetrate e.g. glass, plaster walls, non-metal doors, etc.
4. Selecting a mounting location
Do not install the detector outdoors (A).
Install the detector at the recommended height (B).
When choosing the installation location, keep in mind that the detector performance will
be the best where the expected direction of the intruder movement will be across the
coverage pattern (C).

SATEL GREY / GREY PLUS 5
Do not install the detector in places where it will be exposed to direct sunlight (D) or light
reflected from other objects (E).
Do not point the detector towards fans (F), air conditioners (G) or heat sources (H).
5. Installation
Disconnect power before making any electrical connections.
If the detector is to be pet immune, it must not be mounted on the bracket and
must be installed at a height of 2.4 m with no inclination from the vertical.
1. Remove the front cover (Fig. 6).
2. Remove the electronics board (Fig. 7).
3. Make the openings for screws (Fig. 8 and 9) and cable (Fig. 10) in the enclosure base.
4. Pass the cable through the prepared opening.
5. Secure the enclosure base to the wall (Fig. 8) or a bracket fastened with screws to the
wall or ceiling (Fig. 9). The wall plugs (anchors) delivered with the device are intended for
concrete, brick, etc. For other types of surface (drywall, styrofoam), use the appropriately
selected wall plugs.
6. Fasten the electronics board.
7. Connect the wires to the corresponding terminals.
8. Configure the detector settings.
Configure the anti-masking settings first (see “Configuring the anti-masking settings”).
If you change these settings after you have configured the microwave sensor
sensitivity, you will have to repeat the sensitivity configuration process.
9. Replace the cover.

6. Start-up and walk test
The LED indicator should be enabled during the walk test (see “LED indicator”).
1. Power on the detector. The LED will start flashing red and green to indicate warm-up of
the detector.
2. When the LED stops flashing, check if moving within the detector coverage area will make
the LED light up red. Figures 14 and 15 show the maximum coverage area of a detector
installed at a height of 2.4 m (Fig. 14 –pet immunity option disabled, Fig. 15 –pet
immunity option enabled).

SATEL GREY / GREY PLUS 9
Separate testing of sensors
Microwave sensor testing
1. Power off the detector (if it is powered on).
2. Put a jumper across the PET pins in ON position.
3. Power on the detector. The LED will start flashing red and green to indicate warm-up of
the detector.
4. Within 35 seconds from turning the power on, put the jumper across the PET pins in OFF
position. When the warm-up is completed, the LED will flash green every 2 seconds.
5. Check if moving within the coverage area will make the LED light up green.
6. If necessary, change the sensitivity.
PIR sensor testing
1. Power off the detector (if it is powered on).
2. Put a jumper across the PET pins in OFF position.
3. Power on the detector. The LED will start flashing red and green to indicate warm-up of
the detector.
4. Within 35 seconds from turning the power on, put the jumper across the PET pins in ON
position. When the warm-up is completed, the LED will flash red every 2 seconds.
5. Check if moving within the coverage area will make the LED light up red.
6. If necessary, change the sensitivity.
The detector will automatically exit the separate sensor testing mode after 20 minutes.
Configuring the anti-masking settings
You can configure the anti-masking settings while you test the microwave sensor.
1. Start the microwave sensor testing mode (see “Microwave sensor testing”) and put
a jumper across the PET pins in ON position. The LED will double flash green every
3 seconds.
2. Use the MW potentiometer to set the anti-masking sensitivity.
3. Cover the detector with an object impermeable to microwaves and wait to see when the
LED will light up green. If necessary, change the anti-masking sensitivity.

4. Put the jumper across the PET pins in OFF position. The settings will be saved. The LED
will flash green every 2 seconds to indicate that the detector is back in the microwave
sensor testing mode.
If you fail to put the jumper across the PET pins in OFF position, the changes will not
be saved.
