IR plus Infrared Emitter

The Williams AV IR E4 infrared emitter transmits input from the IR+ IR M1 to guests. In single-channel mode, one emitter provides coverage of up to 18,000 square feet, or 1,670 square meters. Additional IR E4 units can be stacked when an installation requires more coverage. Its black enclosure measures 7.5 inches wide, 1.4 inches high, and 3.6 inches deep, with a weight of 0.8 lb.

Ideal Use Cases

The IR E4 is intended for IR+ systems that use the IR M1 as the source for power, communication, and baseband signals. Its stated coverage makes it suitable for installations requiring infrared transmission across an area of up to 18,000 square feet in single-channel mode. Where one emitter does not provide sufficient coverage, additional units can be stacked to extend the system. This expandable arrangement allows the number of emitters to be matched to the coverage requirements of the installation.

Why Choose This Model

The IR E4 combines infrared transmission, substantial single-channel coverage, and one-cable integration with the IR M1. Power and signal connections do not require separate cable runs between these two components. A single CAT5e cable carries 48 VDC power, RS-485 communication, and the baseband signals used for infrared transmission. The emitter also has a compact physical profile, measuring 7.5 x 1.4 x 3.6 inches and weighing 0.8 lb, or 362 g.

Installation and Integration

The emitter connects to the IR M1 through an RJ-45 jack using a single CAT5e cable. Through this connection, the IR M1 supplies 48 VDC power while also providing RS-485 communication and baseband signals. This consolidated connection defines how the IR E4 integrates with the IR+ system and reduces the number of individual connections required between the emitter and IR M1. The unit is specified for operation at ambient temperatures from 0 to 50°C. The installation environment must be non-condensing and non-corrosive. Additional emitters may be stacked when more coverage is needed.

Performance Highlights

In single-channel mode, the IR E4 covers up to 18,000 square feet, equivalent to 1,670 square meters. It receives input from the IR+ IR M1 and transmits that input to guests. The CAT5e connection carries all required power, communication, and baseband signals from the IR M1. This combination of stated coverage and centralized connectivity supports both single-emitter configurations and expanded arrangements using additional IR E4 units.

What Makes It Different

A defining feature of the IR E4 is the delivery of three essential functions through one CAT5e connection: 48 VDC power, RS-485 communication, and baseband signals for infrared transmission. The same cable connects to the emitter through its RJ-45 jack and originates from the IR M1. The model also supports additional stacked units for installations requiring coverage beyond the area served by one emitter. Its approvals include CE, FCC, RoHS, RCM, WEEE, CB Scheme, ISED, and VCCI.

Final Assessment

The Williams AV IR E4 is a dedicated emitter for transmitting IR+ IR M1 input to guests. It provides up to 18,000 square feet of coverage in single-channel mode and accommodates expanded coverage through additional units. Its single-CAT5e integration carries power, RS-485 communication, and baseband signals from the IR M1. The emitter is covered by a two-year warranty, while accessories carry a 90-day warranty.
