13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in a way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

IMPORTANT

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.

EXTREME CCTV™ will not be responsible for injuries or

damages resulting from the improper installation or use of

any camera sold by EXTREME CCTV™, their agents,

distributors or dealers.

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 BOSCH Service Center for further advice. .

DESCRIPTION

The EX27 integrated 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 to 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 12V dc or 24V ac 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.

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.

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.

GUIDELINES

Three basic requirements must be met before the EX27 can be installed.

1. Voltage Setting

2. Camera Wiring & Settings

3. Video Auto-Iris, CS-mount Lens

Sections 1 to 3 will guide the installer through these settings and adjustments.

1. VOLTAGE SETTING

The camera unit is pre-connected with an electrically isolated power board for 24V ac or 12V dc operation with no wiring change or wiring polarity. See diagram below for wiring details.

Note

: Input voltage is 10.5VDC to 40VDC for DC input.

The AC input range is 12VAC to 28VAC.

3. EX27 VARIFOCAL LENS ADJUSTMENT

FIGURE 3 – 1

EX27 varifocal Lens Focus Adjustment

Vari Focal Lens Adjustments

 Loosen the lens set screws for focus/zoom

adjustments.

 The setscrew marked N ←→ ∞ is used for

image focus.

 The setscrew marked T←→ W is used for

telephoto or wide-angle settings.

 Re-tighten the setscrews after focus

adjustments have been completed.

Use a Neutral Density filter or Infra-Red Pass filter to cover

the lens during focusing to simulate low light conditions on scene for correct 24-hour focusing. For camera with varifocal lens, the camera should be focused with the lens iris fully opened to simulate the worst possible depth of field. Using a Neutral Density filter or Infra-Red Pass filter will ensure the iris is fully open for correct setup and adjustment.

Note that statement above is applicable only for Day/Night

or IR version cameras

SOLUTION

Check input power connections at the cable leads Check for loose wires.

If connected to DC, check voltage input range of 10.5 - 40 V.

If connected to AC, check input voltage range of 12 – 28 V.

Measure the voltage at the Input terminal block.

________________

Poor Video Signal

Determine if wiring polarity at “Video Connector” terminal block is correct. Check BNC connector.

If still no video, connect the camera directly to the monitor. Check the video signal. If okay, the problem is with the interconnections. If still no video, contact

Service Center. See rear page of this manual for contact information.

_________________ Ensure video cable is correctly matched and terminated with 75 ohms at each end. Make sure video cables are similar types.
