Detcon 1010A-FB - Manual (Page 3)

Detcon Model 1010A-FB Gas Detection System PG.3
Upon completion of all field wiring:
Depress the power switch on the controller
assembly front panel. Note that each Model 10A
controller digital display illuminates. Varying readings may occur during sensor warm-up. A 10
second alarm delay will occur on power up.
Refer to section 3.0 for additional sensor start-up
detail.
❏
1.6 START-UP
A remote mounted normally open momentary
switch may be used to reset all Model 10A
controllers. The reset function is effective when
the Model 10A's respective alarms have been programmed in the latching position and alarm
conditions have passed. Each Model 10A controller
has its own alarm reset switch which is discussed
further in section 2.0.

1.5 INSTALLATION
Step 1. Securely mount the 1010A-FB enclosure
in accordance with detail drawing NO. 525.26A.
Step 2. Connect 117 VAC input wiring to the lugless
terminal strip (labled AC IN) on the controller mother
board as detailed in drawing No. 580.27A. Line power
current load is maximum 2 amps. (Note: a jumper
selectable plug located on the power supply may be
used to allow for 220 VAC input.)
Step 3. Connect the 24 VDC standby battery to the
lugless terminal strip (labled DC IN) on the controller
mother board as detailed in drawing NO. 580.27A.
The DC current load is a maximum 3 amps.
Caution: Observe correct polarity when terminating
all input / output field wiring. Failure to do so may result in circuit damage on power up.
Step 4. If applicable, connect a normally open
momentary remote mounted switch to the lugless
terminal strip (labled RESET) located on the
controller mother board as detailed in drawing NO.
580.27A
Step 5. Refer to installation and wiring detail of
remote mount sensor assemblies as detailed in
section 3.0. Terminate field wiring from sensors to
Model 1010A-FB lugless terminal strips located on
the controller mother board as shown in drawing NO.
580.27A.
Note: Based on the application and use of relay
contact outputs, complete all wiring terminations prior
to application of power. Shut-in controls may be
omitted until system test is complete.

1.7 POWER SUPPLY
The power supply on the 1010A-FB may be
changed from 110 VAC to 220 VAC input if available
power should warrant the change. The procedure
does not necessarily require the removal of the
power supply, however, if it is the first time it is done
by a given operator or if the control enclosure is
already wired in (making removal of the mainframe
assembly from the weatherproof enlosure difficult)
it is advisable that the power supply be removed.
The actual procedure is as simple as moving the
plug selectable wire from the 110V terminal to the
220V terminal located on the power supply printed
circuit board. The wire is labled W1 on the power
supply PCB and the terminals are labled 110V and
220v respectively. (1) Remove the power supply (unless experienced
in the procedure) according to the instructions listed
below.
(2) Remove the wire (W1) from the 110V terminal
and plug it into the 220V terminal.
The 1010A-FB is modularly designed so as to avoid
unnecessary down time in the event of component
failure. In the event of a power supply failure, the
power supply may be removed without disconnecting
field wiring. To remove and replace the power supply:
(1) Remove the Model 10A control modules.
(2) Remove the 4 screws from the front panel and
expose the power supply.
(3) Disconnect the 5 pin plug on the left of the
power supply.
