Detcon 1610A-FB - Manual (Page 3)

Detcon Model 1610A-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 1610A-FB enclosure
in accordance with detail drawing NO. 887.26A.
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.
886.27A. 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.
886.27A. 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 (labeled RESET) located on the
controller mother board as detailed in drawing NO.
886.27A.
Step 4. Refer to installation and wiring detail of
remote mount sensor assemblies as detailed in
section 3.0. Terminate field wiring from sensors to
Model 1610A-FB lugless terminal strips located on
the controller mother board as shown in drawing
NO. 886.27A.
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 1610A-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.
