Tile Mounting
2040 Installation Manual Sheet. 3
The 2040 is designed to be mounted in a
suitable ceiling tile where at least 150mm of
space is available behind the tile.
The unit weighs 1.5 Kgs and it is essential
that the tile and its support frame are capable
of supporting the dome without distorting. If
necessary, a back panel should be used
behind the ceiling tile to distribute the weight
to the support frame.
We recommend that the tile should be
removed if possible from the ceiling to
simplify the marking and cutting out of mount-
ing holes.
Using the Mounting template (Fig.1), which is
provided as part of the packaging within the
box, mark out the ceiling hole and centre
points for the 3 off 9mm holes. Cut and drill
the holes as shown in (Fig.2). Replace the
ceiling tile and secure it into position.

Remove the Torx locking screw and separate
the dome assembly from its black plastic
shell by rotating the hemisphere
anti-clockwise and remove the safety bond.
Remove the plug connector from the socket
on the top of the shell. Draw the necessary
cables through the hole in the ceiling and
connect the 24V ac power, coax and optional
RS485 cables as shown in table below.
Reconnect the plug ensuring the correct
position (see Fig. 3 & 4).
Offer up the shell pushing the fixings through
the three screw holes. Tighten the screws,
clamping down on the ceiling tile to secure
the shell in the ceiling cavity.
The shell is now ready to accept the 2040
dome camera module.

Up-The-Coax telemetry control
Commands to control the position of the dome can be
transmitted up the same coax cable used to transmit
the video signal to the recorder station. Different
controllers require different protocols and two switches
are provided to select the desired protocol.
The switches are colour coded, blue and yellow and
located inside the dome camera housing. To access
them rotate the unit until the switch is available through
the access hole at the top of the case (see Fig.6).
Configure the switches for the controller being used as
shown in table below.
The switches are factory set to 253 Den Panel.

RS485 Serial Connection
The coax cable and power wires are always
connected. The RS485 wires are only connected when
an external protocol converter is fitted or an RS485
controller is being used.
Set the individual RS485 address for the dome on the
blue and yellow switches fitted inside the dome
housing. Rotate the housing until the address switches
are accessible through the hole in the top of the
internal case as shown in (Fig. 6.). Set each switch to
its desired position as shown in table 8.
To condition the RS485 lines each 2040 dome is fitted
with a switchable termination resistor as shown in (Fig
8.).When used in a 'Star' configuration (see Fig. 9) all
2040 domes should have their termination resistor
switched IN.
In a 'Daisy Chain' configuration (see Fig. 7) only the
last dome in the chain should have its resistor in with
all other domes having theirs switched OUT. The
default setting has the resistor IN.

Twisted Pair Configuration
2040 domes can be operated on 20mA current loop
twisted pair cabling by using a DRX100 card and power
supply (Dennard part num 95066). In this configuration
the switches must be set to setting 1 (see table 9).
This setting should also be used for alternative local
protocol converters such as the DaxDen.
Note that the DRX100 card also provides 4 local alarm
inputs. For details on connecting the alarms refer to
the DRX100 operating manual.

Dome Mounting
2040 Installation Manual Sheet. 8
Dome Mounting
Once the 2040 dome camera has been configured it
can be fitted into the shell mounted in the ceiling. For
safety reasons, IT IS ESSENTIAL that the safety bond
is used to secure the dome to the shell. The safety
bond is fitted inside the shell and has a small metal clip
on the end of the cable. Offer up the dome camera
and secure the clip to the ring at the top of the clear
plastic case as shown in (Fig. 11).
Having attached the safety bond insert the dome
camera into the shell, ensuring that the safety bond
does not become twisted around the case. Locate the
metal bayonet connector firmly into the top of the shell
and rotate the dome clockwise until the unit latches into
place (Fig. 13).
To secure the unit in place, tighten the single locking
small screw on the hemisphere flange. If the screw
cannot be tightened the dome mechanism may not be
properly located in the bayonet connector. Remove the
unit and repeat the steps above until the dome clicks
into place and the screw can be tightened.
The 2040 dome camera is now ready for use. For
information on how to program and operate the camera
refer to the 2040 programming manual.
