Installation Continued..
5.
Once your SEU and RDU is fixed to wall, you can now r
oute the included CAT5 cable between
the
SEU and RDU.
The
CAT5 cable can be run
through the wall/conduit or fixed to the wall using
cable
clips.
Finally,
p
lug the CAT5 cable into
the designated ports on both units.
Please note,
2
additional RDUs can
be connected to the first RDU
as long as the total cable length between the
farthest RDU and
SEU is less than 300ft.
(91m).
6.
When the power has been connected, The SEU and the RDU will perform a self-check,
or 30
minute countdown, and
then begin to work
and read the appropriate gas concentrations
.
**
If the
cable between the SEU & RDU is not securely connected, the
yellow fault LED on the
SEU will
blink after startup. If
the
cable is inserted into the wrong
port
on
the back of the
RDU,
after about
one minute, “Er7” will flash on the RDU display. Securely plug
the
cable into the
correct port on
RDU for the unit to function normally.

7.
To
test the system, use the DIAG function.
The five LED’s will blink and the buzzer will
sound on
both the SEU and RDU. Then both LCD
screens will show the same
information. This verifies that
alarm is ready.
8.
As a reminder, The RAD-0002 has 3 relay outputs connected to the programmed alarm
settings.
All relays are normally open/closed dry contacts.
Any of the relays can be used to control an
external device (fan, HVAC system, etc.) or can be
wired to the fire alarm panel directly. The
relays will trigger when the O2 concentration exceeds
the programmed alarm level.
