Installation
Refer to product manual for coverage of the detector and installation location.
NOTE
: De-energize Power during installation and wiring. Use 12 to 22 AWG wire.
Mounting
- The device mounts on a 4” square (or 4x4) electrical box. Do not
mount the device inside another box, unless it has good air flow through it.
Power Supply
- Use Class 2 power supply only for 6-series. Power connector does
not have polarity preference
.
•
Connect the device to the control cables with terminal plugs. Connect the
cable to corresponding terminal modular connector (refer to Figure 1 and
2).
•
For 4-20mA connection, connect the wire to appropriate polarity.
•
Relay connectors labeled ‘A’ and ‘B’ can be configured to normally open
(NO) or normally closed (NC) via configuration menu.
•
For Relay Connectors labeled ‘NC’, ‘COM’ and ‘NO’, NC refers to normally
closed, COM refers to common, and NO refers to normally open.

Operations
NOTE: Refer to product User Instructions to get additional details on product
feature and operation.
Power Up
– Macurco 6/12 Series detector will execute a self-test cycle any time
power is dropped and reapplied (i.e. power failure). During the test, the indicator
LED will flash green and count down is displayed. After countdown is over, the
indicator LED will turn solid green and the detector is ready for use.
Status Indicator
- From
lowest
to
highest
, the alarm priority is as follows:
Awareness Alarm, Alarm 1, Alarm 2, Alarm 3, Trouble Fault.
The following alarm behavior is observed with the default settings (display “On”,
buzzer “On”)
1
:
•
Clean Air
–The device will show the current gas concentration.
1
•
Alarm Level
– When the gas concentration is beyond the alarm level
threshold, the corresponding alarm relay will engage and the display will
flash between ‘ALr’ (‘ALrX’ for CD-6B ,where X is 1,2 and 3 for Alarm 1, 2
and 3 respectively) and current gas reading, and buzzer will beep every
second.
1
•
Trouble
– If the detector is in a trouble state, the “t” Error code will be
displayed (t01, for example). The green status indicator LED light will flash,
and the buzzer will beep intermittently. If the Trouble Condition setting is
enabled (default is “OFF”), Alarm Relay (Alarm 1 Relay for CD-6B) will
activate.
•
Calibration Due
– If the device is within 1 month of calibration period and
Calibration Period functionality is enabled, then the display will flash
between “dUE” and current gas concentration. Calibration Due is resolved
only with a successful field calibration.
