Low Temperature Detector (EL-2663)
The
EL
‐
2663
is
a
wireless
low
temperature
detector
designed
for
use
with
Electronics
Line
3000’s
supervised
wireless
range
of
receivers.
The
EL
‐
2663
includes
a
thermostat
that
causes
the
transmitter
to
send
an
alarm
signal
when
the
temperature
falls
to
approximately
5ºC
(41ºF).

Mounting Location
Consider
the
following
when
choosing
a
mounting
location:
Do
not
locate
the
detector
near
heaters
or
boilers
that
may
stay
warm
long
after
the
temperature
has
dropped
in
other
parts
of
the
premises.
Mount
the
detector
in
a
location
that
is
likely
to
get
cold
first
when
the
temperature
drops.
Try
to
locate
the
detector
in
a
location
where
there
is
good
air
circulation.
Installation Instructions
1.
To
open
the
housing,
insert
a
small
screwdriver
at
the
bottom
of
the
unit
between
the
front
and
back
cover
and
twist
the
screwdriver
to
release
the
cover.
2.
Remove
the
divider
separating
the
battery
from
the
contacts
on
the
battery
holder.
When
you
apply
power
and
the
Tamper
switch
is
open,
the
EL
‐
2663
enters
Test
mode
during
which
a
transmission
is
sent
every
few
seconds.
You
can
terminate
Test
mode
by
closing
the
Tamper
switch.
Test
mode
is
automatically
terminated
after
approximately
five
minutes.
Due
to
the
occurrence
of
voltage
delay
in
lithium
batteries
that
have
been
in
storage,
the
batteries
may
initially
appear
to
be
dead.
In
this
case,
leave
the
unit
in
Test
mode
for
a
few
minutes
until
the
battery
voltage
level
is
stabilized.
3.
While
the
EL
‐
2663
is
in
Test
mode,
set
the
receiver
to
Registration
mode
and

LED
indicator
lights
up
at
least
twice.
After
registration,
momentarily
close
the
Tamper
switch
to
terminate
Test
mode.
