2.0 SCOPE
The information contained in this manual covers the
ED25/ED2520/ED2620/ED27/ED2720 Series Environmental Domes.
2.1 DESCRIPTION
The ED25/ED27 Series can be ordered as a dome only
or with factory installed heater/blower and service light.
Other options include factory assembled integral pan/
tilt and/or Coaxitron/Wiretron receiver/driver.
The ED25 Series is designed for flush mount or pen-
dant mount applications.
The ED25/ED2520/ED2620/ED27/ED2720 Series of
environmental domes have been designed primarily for
outdoor applications, but also can be used indoors. The
14-inch diameter black opaque lower dome has a
smoked viewing window with less than 1 f-stop light
loss. This provides for effective camouflage of the
CCTV security/surveillance system without compromising the quality of the video picture.
The ED2620 Series is a pendant mount dome with in-
tegral pan/tilt and is designed specifically for hard-wire
control applications.
The ED27 Series includes an integral arm and can be
used for wall, parapet, or universal mount applications.

3.0 INSTALLATION
CAUTION: Make certain that the mounting
surface is capable of supporting the full load of
the mount, pan/tilt, camera/lens and enclosure
• Handle the lower dome with care so as not to
scratch or get fingerprints on the viewing window.
• When installing the unit, loosen the two (2) fasteners and remove the pan/tilt or camera mount to
reduce the total weight of the enclosure.
• When the pan/tilt or camera mount is removed,
install the camera/lens and make sure the electrical connections to the pan/tilt (camera power, lens
power and video) are made.
• When closing the enclosure, be sure the drive tab
on the dome engages the slot on the drive arm of
the pan/tilt.
3.1.1 FMED25 Flush Mount Installation
To mount the enclosure using the FMED25 flush mount,
perform the following steps. Refer to Figure 2.
1. Secure the FMED25 flush mounting plate to a suitable surface and secure with suitable fasteners (not
supplied) capable of supporting the weight of the
dome, pan/tilt, camera and lens. Due to the wide
range of installations this mount could be used in,
drilling of holes in the mounting plate will be required.
2. Install the provided gasket over the four (4) studs
on the FMED25 mounting plate.
3. Align the four (4) studs in the FMED25 with the
four (4) holes in the top of the dome. Then, secure
the dome to the mounting plate by using the four
(4) 1/4-20 nuts supplied with the mount.
WARNING: Do not rotate pan/tilt by hand.
Rotate by controller only.
3.1 MOUNTING
The ED25/ED2520/ED2620 Series of environmental
domes can be installed by using one of the following
mounts:
• FMED25 Flush mount adapter. Adapts dome
to ceiling. Required for all flush
mount applications.
• PAED25 Discontinued. (Use PA102 with
ED27 Series dome.)
• PMED25 Pendant mount adapter.
• UMED25 Discontinued.
• WMED25 Discontinued. (Use ED27 Series
dome with integral mount.)
Mount the enclosure according the following directions
for the selected mount.

3.1.2 PMED25 Pendant Mount
Installation
3.2 PAN/TILT INSTALLATION/
REMOVAL
To mount the enclosure using the PMED25 pendant
mount, perform the following steps. Refer to Figure 3.
1. Screw the PMED25 pendant mount to a suitable
length of 1-1/2-inch MNPT threaded pipe which
has been securely fastened to a surface capable of
supporting the weight of the dome, pan/tilt, camera and lens.
(The Pelco MRCA ceiling adapter is recommended
for ceiling mounting applications.)
2. Install the provided gasket over the four (4) studs
on the PMED25 mounting plate.
3. Align the four (4) studs in the PMED25 with the
four (4) holes in the top of the dome. Then, secure
the dome to the mounting plate by using the four
(4) 1/4-20 nuts supplied with the mount.
The following installation instructions are for removing/installing the pan/tilt assembly.
1. The pan/tilt is secured to the back box by two (2)
1/4-20 nuts which hold the pan/tilt mounting
bracket to the integral studs on top of the back box.
2. To remove the pan/tilt, first position the pan/tilt by
using the controller only so it is perpendicular with
the mounting nuts. Then, use a 7/16" socket on a
long extension to reach the nuts holding the pan/
tilt.
3. The mounting nuts need not be removed, just loosened. Once the nuts have been loosened, slide the
pan/tilt so the nuts fit through the “key holes”.
4. To install the pan/tilt, reverse the procedure.
3.3 ELECTRICAL WIRING
The following installation instructions describe how to
connect power to the camera, lens and pan/tilt.
1. The supply circuit should be connected to the input circuit board (pins 8, 9 & 10) as shown in Figure 7.
Figure 3. PMED25 Installation
3.1.3 ED27 Wall Mount Installation
The following installation instructions are for mounting the ED27 Series mount with integral wall mount
arm to an appropriate surface.
1. Mount the mounting plate of the ED27 enclosure
on a suitable surface and secure with suitable fasteners (not supplied) capable of supporting the
weight of the dome, pan/tilt, camera and lens.
2. The pan/tilt and video connection to the receiver/
driver are shown in Figure 8.
3. Basic motor wiring detail for the pan/tilt assembly
is shown in Figure 9.
4. The dome drive pinouts for all models are shown
in Figure 10. Select the appropriate model for your
installation.
