Mounting Configurations

For wall, pendant & snowdrop mounted domes attach the supplied safety bond, as shown in Fig.3, under
existing fixing in (position A) (use M6 plain washer supplied). Clip carbine at other end to eyelet (B) on
bracket to secure.
For standard ceiling mounted domes attach the supplied safety bond, as shown in Fig.4. Fit bond over M6
stud (position B) and secure with M6 nut, plain washer & spring washer supplied. Clip carbine to eyelet (E)
on dome to secure (see sheet 5 ‘Ceiling mounting instructions’ for details on eyelet mounting)
Note: Always support dome with bond prior to mating connector C. Weight of dome should be
supported by bond ensuring no stress is placed on centre connector C at any time.

Cut/drill hole pattern in ceiling as shown in (fig.5) (Note: fixings for hole (A) are not supplied by Dennard
due to the variations of ceiling materials / thicknesses found on site. Please choose suitable fixings, with
countersunk head, for your application.) Attach mounting disc (B) to ceiling with chosen fixings and screw 4
off M6 x 16 soc cap hd. screws supplied into bushes as shown (C). Attach transfer disc (E) to top of dome
enclosure (G) with 4 off M6 dome hd. self tapping trilobular screws (D) pre-fitted (fig.6) (Note: Fit safety
bond bracket (F) as shown) Offer dome enclosure to ceiling mounting disc (fig.7) engaging the screw
heads (C) into keyhole slots (G). Twist to locate and tighten fixings
(C) to secure. Please ensure safety bond is fitted as descibed on sheet 4.

A. Remove bracket base casting by unscrewing outer trilobular fixings, then assuming masonry wall mounting,
mark & drill 4 x Ø12 holes using bracket base casting as pattern, shown above.To assist with orientation
flats are
provided on all 4 axes allowing the use of a spirit level for alignment. (Fig 8) (use goggles when drilling)
B. Insert 4 x M6 Rawlbolts into wall until flush.
C. Offer bracket base casting into position & screw wall fixing screws through into inserts.
D. Tighten fixings to secure. Note: An optional spreader plate (/SP) is recommended when fixing to brickwork
to reduce the ‘pull out’ forces on a single brick.(Available from Dennard on request)
Note: Locating a dome on a corner of a building will give an increased area of surveillance. For this reason
Dennard are able to offer an optional corner bracket (/CB) to adapt the standard wall bracket.
E. Thread cable from bracket through cable entry hole in bottom of bracket base casting, then replace
bracket. (Fig 9)
F. Using supplied trilobular fixings attach bracket to base casting as shown. (Fig 10)
Wall Bracket Mounting

Cut/drill hole pattern in ceiling/tile as shown in (fig.11). Attach the mounting frame to the dome as shown in
fig.12 using 4 off M6 dome hd. self tapping trilobular screws (pre-fitted). Pass dome complete with
attached mounting frame (item A) through ceiling tile from beneath and clamp to tile using clamp ring
(item C) from above. Secure with 4 off M6 fixings (item D) as shown in (fig.13). If not already fitted adhere
Velcro® strips to hemisphere flange and likewise to the inside face of the trim bezel suppled. Simply offer
bezel over hemisphere into position aligning Velcro® strips to ensure a good bond is achieved as shown in
(fig.14). Fit safety bond supplied to attachment point shown in (fig.12).

D. Tighten 4 top mounting fixings with 4mm A/F Hexagonal key supplied to secure.

The Type 2050 external connections are via an IP66 Amphenol connector with 3 metre composite cable
flying lead comprising co-ax, power pair & RS485 pair. This lead should be connected to the boxed
P.S.U. supplied with the dome. The connections are as follows:
Fig.16 Electrical connections
Red wire.......24V a.c. live
Blue wire......24V a.c. neutral
The co-ax and power wires are always connected, the RS 485 wires are only connected when an
external protocol converter is fitted or an RS485 controller is being used.

B
C
Address switches
The Type 2050 can be controlled via RS 485 com-
mands or ‘up the co-ax’
With RS 485 control each dome has to be individually
addressed using the Blue and Yellow rotary address
switches following the address chart on the previous
page. For ‘up the co-ax’ control using the built in pro-
tocol converter the same address switches are used
to select the protocol format of the controller being
used i.e.
BAX AC PANEL.................Blue.F Yellow.C = 252
For: Baxall a.c. controllers
DEN PANEL.......................Blue.F Yellow.D = 253
For: Dennard, BBV & DM Sprite controllers
BAX DC PANEL................Blue.F Yellow.E = 254
For: Baxall d.c. controllers
For ‘up the co-ax’ control using external protocol con-
verters like the drx 100 or DAX-DEN the address
switches should be set to
Blue.0 Yellow.1 = 1
To access the address switches remove the outer
hemisphere and inner shroud as shown in A & B.
Picture D shows the location. This operation should
be carried out in an office type environment to avoid
ingress of moist air.

Addendum.2. Type 2050/FA (Electrical Connections)
Addendum.3. Type 2050/FA (‘Zoom Cam’ Set Up)
2050 coax operation manual Sheet. 13

Moving cameras can be positioned remotely, fixed
attitude modules require manual adjustment to position the
camera. Follow the procedure below to set-up your required
picture frame.
1. Unscrew the 6 fixings securing the outer hemisphere to the
casing and remove.
2. To adjust the pan position of the camera, grip the inner hemi-
sphere and rotate. This adjustment provides 180º of pan right &
left movement. Tip. Do not wind more than 180º in one direction
as this will stress the connections to the camera.
3. To adjust the tilt position grip the camera platform (accessible
through the camera viewing slot) as shown and move. This
adjustment provides tilt up/down. See Addendum 3 for ‘zoom
cam’ set-up.

The Type 2050/FA Camera Dome is supplied complete with an IP66 ‘Amphenol’ 7 way connector and 3
metre multicore with Co-ax flying lead assembly. The Amphenol connector mates as shown in fig.16 to
the top of the dome. The table below details the flying lead functions.

Type 2050/FA (Fixed Attitude Electrical Connections)

Type 2010ZC/COL & /COLMON are equipped with the ‘zoom cam’ high resolution
camera. See instructions below.
1. Control
Remote zoom control requires a Dennard, BBV or DM telemetry controller. as well as the removal of link ‘A’
(see point 6) if not already disconnected. Depress the zoom buttons or use the joystick pan axis to operate.
If no control is available the camera can function as a ‘fixed lens’ (see point 6)
2. Presets
The ‘zoom cam’ can store up to 8, user definable, zoom presets within memory. Please refer to the relevant
controller instructions for preset programming.
3. Default position
After a period of inactivity (default 1min.) the ‘zoom cam’ will revert to preset 1 (wide angle if no preset
stored). On Dennard & BBV controllers only use the ‘Patrol 2 delay program’ to adjust the time interval.
Intervals are 1,2,3,4,5,6,8 & 10 minutes for keys 1-8.
4. Patrol
The ‘zoom cam’ patrol feature can be used to sequence between the preset positions. Follow the relevant
controller instructions to setup ‘Patrol 1.’ Patrol mode is cancelled with any manual zoom action.
5. Video level adjustment
Video level is factory set, but can be adjusted by turning VR1 located just above the link’A’ on the receiver
board. (see opposite) This adjustment may be required to lighten / darken the picture depending on the dis-
tance of co-ax required.
6. Fixed lens
When no remote control is available the ‘zoom cam’ can function as a ‘fixed lens’ (i.e. the camera can be
manually zoomed (locally) to a preset position)
a. Ensure link ‘A’ (supplied) is fitted, as shown, between pins 9 & 10 on power up
b. Frame the preset picture required by zooming using the buttons provided on the side of the camera.
c. Temporarily remove the link ‘A’ for a few seconds and then refit. (The link must be left in permanently)
Note: to revert back to ‘zoom cam’ operation the link must be removed and power re-applied.
