Satel COBALT, COBALT Plus / Pro - Digital Dual Technology Motion Detector Manual

FEATURES

• Combined PIR and microwave technology.
• Dual [COBALT, COBALT Plus] or quad [COBALT Pro] element pyrosensor.
• Fully digital motion detection algorithm.
• Digital temperature compensation.
• Selectable operation modes: basic or counting.
• Microwave based anti-mask feature [COBALT Plus, COBALT Pro].
• Low supply voltage signaling (voltage drop below 9 V ±5%).

OPERATION MODES

Basic – the detector indicates an alarm if both sensors detect motion within a time period shorter than 10 seconds.

Counting – the detector indicates an alarm if both sensors detect motion within a time period shorter than 10 seconds or if the microwave sensor is activated 16 times in less than 30 minutes without activation of the infrared sensor.

ANTI-MASK FEATURE

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 results in opening the antimasking relay contacts for two seconds. Objects permeable to microwaves, but isolating the infrared radiation are not detected by the anti-masking feature.

1. terminals:
   WRN – a nti-masking relay (NC) [only COBALT Plus and COBALT Pro];
   TMP – tamper contact (NC);
   COM – common ground;
   12V – power supply input;
   NC – alarm relay (NC).
2. microwave sensor.
3. two-color LED to indicate:

• alarm – LED lit up red for 2 seconds;
• motion detection by one of the sensors – LED lit up green for 2 seconds;
• warm-up – LED flashing alternately red and green;
• low supply voltage – LED lit up red.

4. potentiometer for sensitivity control of the microwave path.
   Please bear in mind that microwaves can penetrate e.g. glass, gypsum walls, non-metallic doors, etc.
5. pyroelectric sensor.
6. tamper contact.
7. fixing screw hole.
8. detector configuration pins:
   PIR SENS. – setting detector sensitivity (see Fig. 2);
   MODE – selecting the detector operation mode:

• pins shorted – basic mode;
• pins open – counting mode.
  LED ON/OFF – enabling/disabling the LED signaling. The signaling is enabled when the pins are shorted.
