For best results, please read this Instruction Booklet prior

to installing the EX27 camera.

EU Directives covered by this declaration: 72/9/EC Low Voltage Directives 89/336/EEC Electromagnetic Compatibility Directive

This installation should be made by a qualified service

person and conform to all local codes.

Bosch Security Systems will not be responsible for

injuries or damages resulting from the improper installation

or use of any camera sold by Bosch Security Systems,

NOTE: This equipment has been tested and found to comply with the limits for a digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. As part of its’ normal operation this device can generate radio frequency energy and if not installed and used in accordance with the installation manual may cause interference to radio communications. However, there is no guarantee that interference will not occur on a particular installation. If the device does cause interference to radio or television reception the user is encouraged to try to correct the interference by one or more of the following measures:

1) Fit Ferrite beads on all cable to and from the power supply box, within the box walls.

2) Route the composite cable between the camera and the power supply in steel conduit piping over the entire run of the cable up to and including connection to a deep conduit base fitted under the camera and a conduit fitting adaptor in the wall of the PSU box.

3) Contact a Bosch Service Center for further advice.

1. DESCRIPTION

The EX27 camera is an all-weather system that includes all of the best features of a “plug and play” camera without compromise to CCD optics and lens quality.

Full size vari-focal auto-iris lenses are integrated as standard equipment for simplified installations. High resolution extended day/night CCDs ensure that a picture is received under extreme outdoor lighting conditions.

The EX27 is rugged, compact, power protected, weather sealed, easily installed and designed for use in industrial applications.

A voltage regulator circuit automatically allows for 12VDC or 24VAC operation without any wiring changes. Its wider voltage range also provides protection from voltage surge, transient spikes, and reverse voltage.

The EX27 is available in several models to meet individual requirements or specific needs.

2. UNPACKING

Care should be taken when unpacking. Check the parts list and confirm all items have been located. Inspect the equipment thoroughly to ensure nothing was damaged in transit.

5. INITIAL PREPARATIONS

 Determine the operating voltage at the

installation site.

 All cameras have been tested prior to

shipment.

Select a suitable location that is protected from accidental damage, tampering, and environmental conditions exceeding the camera’s specifications.

Caution: The selected mounting location should not place the camera in a situation where its environmental specifications could be exceeded.

Ensure the selected location is protected from falling objects, accidental contact with moving objects, and unintentional interference from personnel. Follow all applicable building codes.

6. GUIDELINES

The following installation guidelines must be followed:

 Locate the camera such that it cannot be

easily interfered with, either intentionally or accidentally.

 Select a mounting surface capable of

supporting the combined weight of the camera and mounting hardware under all expected conditions of vibration and temperature.

 Secure all cabling.  Installations on drywall must use a ¼” bolt

and drywall butterfly type anchor or superior connection.

7. VOLTAGE INPUT

The camera unit is pre-connected with an electrically isolated power board for 24VAC or 12VDC operation with no wiring change or wiring polarity. See figure 7-1 for wiring details.

Note

: Input voltage is 10.5VDC to 40VDC for DC

input. The AC input range is 12VAC to 28VAC.
