Frequently Asked Questions - GREY Plus Satel

What is the recommended installation height for the GREY Plus?

The recommended installation height is 2.4 m for optimal performance and pet immunity.

How does pet immunity work?

The detector ignores pets up to 15 kg while still detecting human intruders.

What is the anti-mask feature?

The anti-mask feature uses the microwave sensor to detect objects moving 10-20 cm from the detector, triggering the anti-mask output.

How do I perform a walk test?

Ensure the LED is enabled, power on the detector, wait for warm-up (35 s), then walk across the coverage area. The LED will light red on alarm.

Can I test the PIR and MW sensors separately?

Yes, use the PET jumper pins to enter separate testing modes. For microwave test, set PET ON; for PIR test, set PET OFF.

What do the LED colors indicate?

Red/green flashing = warm-up; green = sensor detection; red = alarm; flashing red = alarm memory; steady red = trouble.

How do I enable/disable alarm memory?

Connect the MEM terminal to common ground to enable alarm memory. Disconnect to disable.

How do I wire the detector?

Use terminals for power (12V, COM), alarm (NC), tamper (TMP), and anti-mask (AM). Configure outputs via pins (2EOL).

What happens during a voltage drop?

If voltage drops below 9 V for over 2 seconds, the detector signals trouble via alarm output and red LED.

Is the anti-mask feature compliant with EN 50131-2-4?

No, the anti-mask feature does not meet EN 50131-2-4 requirements.

1. Specifications 10

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 kΩ).
• 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.

i 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.

⑨ potentiometer for adjustment of PIR sensor sensitivity.
⑩ potentiometer for adjustment of microwave sensor sensitivity.

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).

• 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.

1. 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).

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.

i 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.

i

If you fail to put the jumper across the PET pins in OFF position, the changes will not be saved.
