DIGITAL DUAL DETECTORS
COBALT, COBALT Plus,
&COBALT Pro
cobalt_dwa_e 03/04
A microwave (MW) sensor and
a dual pyro electric element are
used in the COBALT detector
construction.
An additional feature in the
COBALT Plus is the antimasking
function, realized by microwave
sensor. It signalizes objects
moving close in front of the
detector, thus preventing any
attempts to cover it.
The COBALT Pro employs an
MW sensor and a quad pyro
element. The detector is also
provided with the antimasking
function.
CONTACTS:
COM - ground (0V)
12V - supply input (9-16V DC)
NC - alarm relay (NC)
WRN - antimasking relay (NC) -
only the COBALT Plus and
COBALT Pro detectors
TMP - tamper contact (NC)
Four pairs of pins are used for setting
the detector working parameters (see
Table).
The COBALT, COBALT Plus
& COBALT Pro dual detectors can
operate in two modes: the basic mode
or the microwave counting mode (MW).
In the basic mode the detector will only
generate an alarm when motion is
detected by both sensors. The first
system (infrared or MW) which detects
a motion will activate a 10-second time
interval during which the other sensor
must also detect motion for the
detector to generate an alarm signal. If the other sensor fails to confirm the alarm
condition within 10 seconds of the motion being detected by the first sensor, the sensor
will generate no alarm.

When in the microwave counting mode (MW), the detector will generate an alarm both
in the above mentioned case, upon detection of a motion by both systems, as well as
after 16 excitations of the microwave sensor, with no violation of the PIR sensor.
NOTE: Remember to set an appropriate sensitivity of microwave channel
detection, since the microwaves are capable of penetrating, for example,
through gypsum walls, doors, etc., which may cause generation of false
alarms.
The LED allows the installer to check the detector for correct functioning and to
approximately determine the protected area:
-the LED lights red– alarm,
-the LED lights green – excitation of PIR or MW system.
For 30 seconds after the power is turned on, the detector remains in a starting state,
which is signalized by a rapid blinking of the LED, alternately, green and red. Only then
the detector enters its operational readiness state.
The detector monitors the supply voltage. If the voltage drops below 9V (±5%) for more
than 2 seconds, the detector will signalize a violation state until a voltage of minimum 9V
(±5%) is restored.
INSTALLATION
The detector is designed for indoor installation. It can be mounted on the wall, either
directly or on the included holder.
Prior to installation of the detector housing, remove the electronics board and brake out
adequate openings for screws and cable in the rear panel of the housing.
It is advisable that you exercise particular care to prevent the pyro element from
getting dirty or damaged during installation.
Figure 2 shows typical examples of connecting the detectors in EOL (parameter)
configuration and 2EOL (two-parameter) configuration. Resistors should be mounted
inside the detector housing.

LENSES
In the detector is mounted a wide angle lens, however, it is possible to replace it by
buying another lens with different characteristics (range, number of beams, angle of
view). Lenses are available with the following characteristics:
It. Lens type Range Angle of view
1 wide angle 9m 101°
2 extra wide angle 15m 141,2°
3 long range with access zone
monitoring 30m main beam - 3m wide (at the end of range)
4 vertical barrier 22.5m 2.2m wide (at the end of range)
NOTE: The detector operating range should be selected to match the size of space
where the detector will be installed. The size of the space along the main
direction of detector positioning is not to be less than 1/3 the nominal range of
the detector. Improper selection of the lens may cause excessive sensitivity
and trip false alarms.
