2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X ,6 or 6P enclosure,
it is designed for indoor use only and it must not be installed where exposed to rain and
moisture.
3. Use only installation methods and materials capable of supporting four times the combined
weight of the enclosure/pan and tilt/camera/lens.
4. Only use replacement parts recommended by Pelco.
5. The camera and lens combination shall not exceed 10 pounds (4.5 kg).
The product and/or manual may bear the follo wing marks:

DESCRIPTION
The EH2100 and EH2100P are low profile ceiling enclosures designed for mounting in hard or
suspended ceilings. Their compact design complements any business or office decor and provides maximum surveillance for fixed CCD camera applications .
The upper section mounted above the ceiling is constructed of aluminum to meet most fire code
requirements. The EH2100 has a riveted back box. The EH2100P has a fully welded and sealed
back box, which has been found suitable for use in return air-handling plenums by Underwriters
Laboratories, Inc.
The EH2100/EH2100P are engineered for ease of installation and service. Because of its lightweight design, the upper section can be mounted directly on a ceiling tile without the use of
added support. A clear window provides for a discreet installation.
The lower section is hinged to provide convenient access for adjusting the camera and lens.
The adjustable camera mounting sled allows the camera to be positioned vertically or horizontally, depending on the camera size.
Models
EH2100 Low profile ceiling enclosure with riveted back box for use with solid-state
EH2100P Same as EH2100 except has fully welded and sealed back bo x
CCD cameras; for use in hard or suspended ceiling applications
INSTALLATION
To install the EH2100/EH2100P perform the following steps:
1. Determine the location and direction of the enclosure.
NOTE:
Flange extenders have
been supplied to support the enclosure if adequate mounting
support is not available.
HARD CEILING - Cut an opening in the ceiling. Avoid cutting into the ceiling support
structure (rafters and joists).
SUSPENDED CEILING -The E2100 rotating mounting plate may be used when installing
the EH2100/EH2100P into a suspended ceiling. To install the
E2100 follow the instructions supplied with the mounting plate.
2. Open the cover of the enclosure to expose the mounting holes in the flange.
3. Remove the appropriate knockouts (EH2100 only) needed for camera power and video
wiring. The EH2100P must have feedthrough holes drilled in needed locations.
4. Insert the enclosure into the opening and secure with the appropriate fasteners. The
EH2100P fasteners must meet plenum standards.
5. Mount the camera and lens onto the adjustable mounting bracket. Adjust the position of the
camera and lens to clear the enclosure cover when closed. Tighten the mounting bracket
fasteners.
6. Route the appropriate cables into the enclosure. Make all necessary electrical connections.
Refer to Table A for the type of video coaxial cable to use. Refer to Table B for 24 VAC wiring distances.
7. Close and lock the cover.
Table A. Video Coaxial Cable Requirements
Cable Type* Maximum Distance
RG59/U 750 ft (229 m)
RG6/U 1,000 ft (305 m)
RG11/U 1,500 ft (457 m)
* Minimum cable requirements:
75 ohms impedance
All-copper center conductor
All-copper braided shield with 95% braid coverage
EXAMPLE:
An enclosure that
requires 80 vA and is installed 35
feet (10 m) from the transformer
would require a minimum wire
gauge of 20 Awg.
NOTE:
Distances are calculated
in feet; values in parentheses are
meters.
Table B. 24 VA C Wiring Distances
The following are the recommended maximum distances for 24 VAC applications and are calculated with a 10-percent voltage drop. (Ten percent is generally the maximum allowable voltage
drop for AC-powered devices.)
