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.

DESCRIPTION

The EX72LED Explosion Protected Infrared

Illuminator Unit has been designed for use in extremely hazardous environments not suited for conventional surveillance applications.

The Illuminator housing consists of a heavy-duty aluminum casting and a chemical resistant viewing window. In addition, the housing is

NEMA rated.

The EX72LED incorporates a powerful, highefficiency 100 LED array providing up to

60 ft. (18 m) night-vision performance when used with IR sensitive cameras.

A voltage regulator circuit allows for 12V dc or

24V ac operation, and a range in between, also providing protection from voltage surge, transient spikes, and reverse voltage.

INITIAL PREPARATIONS

 Determine the optimum location for the

EX72LED Infrared Illuminator Unit.

Section 1: Mounting-Unit Housing.

 Determine the operating voltage at the installation site. The Illuminator has been pre-wired at the factory for 24V ac operation.

Section 2: Voltage Input Connections.

 All Illuminators have been tested prior to shipment. After any internal wiring has been reconnected due to voltage changes, it is advisable to check the illuminator’s operation before installation.

GUIDELINES

The installation of the EX72LED IR Illuminator is shown in Sections 1 and 2 listed below.

It is important that these steps are followed in sequence:

1. Mounting – Unit Housing

2. Voltage Input Connections

1. MOUNTING - UNIT HOUSING

Caution: Install with the appropriate screws or drywall anchors to suit the mounting surface. Select a suitable location that is protected from accidental damage or tampering, and environmental conditions that could exceed the unit’s specifications.

See page 14.

Caution: 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



The following installation guidelines must be followed:

• Locate the Illuminator unit such that it cannot be easily interfered with, either intentionally or accidentally.

• Select a mounting surface capable of supporting the combined weight of the

Illuminator unit and its mounting hardware under all expected conditions of vibration and temperature.

• Secure all cabling.

7

The cover of the EX72LED must be removed prior to mounting. The set-screw in the cover must be loose prior to the cover’s removal.

Ensure the gasket is not displaced during this procedure. Re-attach the cover after the unit has been mounted.

2. VOLTAGE INPUT CONNECTIONS

The EX72LED, when shipped, is preset and connected for 24V ac operation.

For 12V dc voltage input operation, refer to the wiring steps below.

Caution: ESD protection. It is recommended that the installer wear an ESD strap or discharge any static electricity to ground before handling any electronic components.

Note: Input voltages between 13.5 and 28V, ac or dc, will work in the 24V ac input setting.

Step 2.1 - If 12V dc operation is required, see

Figure 2 – 1 for access instructions to the VRB (Voltage Regulator

Board).

Step 2.2 - Connect the power wires for 12V dc.

Refer to Figure 2 – 2.

Step 2.3 - Tighten the wiring into the terminal block and test the LED Array module before re-assembly.

10

For access to the VRB, unscrew the Illuminator

Cover and remove the LED Array module with the supplied Allen key as shown below.

The LED Array module is held in place by three

M3 socket screws (A).

PROBLEM

Fuse Blows

(Customer Power Supply)

Don’t know if LEDS are

“ON”

POSSIBLE SOLUTION

- Check fuse rating.

- Check for shorting between

the housing and the

input power.

850nm LEDs will have a faint red glow when “ON”.

940nm LEDs are covert.

Aim the LEDs directly at an

IR sensitive camera to see the lights or wait for the

LEDs to warm up (two minutes).
