Ritron RQX-411 UHF Q-Series Analog Callbox – High-Visibility Green

Reliable communication is essential when employees, visitors, drivers, contractors, and security personnel need a convenient way to contact two-way radio users from fixed locations. The Ritron RQX-411 UHF Q-Series Analog Callbox provides a practical wireless communication solution for entrances, loading docks, maintenance areas, warehouses, manufacturing facilities, construction sites, and other locations where quick radio access is important.

The RQX-411 is a UHF analog callbox designed for the 450–470 MHz Part 90 business-band frequency range. Its high-visibility green enclosure makes the callbox easy to identify, while its rugged polycarbonate housing is designed for professional indoor and outdoor applications.

Unlike a conventional wired intercom, the Q-Series callbox communicates through an existing compatible analog two-way radio system. Ritron designed the Q Series to be installed where communication is needed without requiring communication wiring or trenching.

Wireless Communication Where You Need It

The Ritron RQX-411 provides a dedicated communication point that can be positioned away from the main radio users.

For example, a facility can place a callbox at a gated entrance so visitors or delivery personnel can communicate with security or staff carrying compatible UHF analog radios. Similarly, a callbox can be positioned at a loading dock, maintenance area, production floor, or remote section of a property.

Ritron states that Q-Series callboxes can provide long-range voice communication of up to 1 mile line-of-sight, depending on environmental and installation conditions.

UHF 450–470 MHz Communication

The RQX-411 is designed for UHF operation from 450–470 MHz and is intended for licensed Part 90 business-band applications.

UHF can be particularly useful in commercial facilities, buildings, warehouses, campuses, and other environments where radio users need dependable communication around structures and equipment.

The callbox uses one analog RF channel and supports 12.5 kHz narrowband operation.

High-Visibility Green Housing

The high-visibility green enclosure is an important feature for locations where the callbox needs to be quickly recognized.

A clearly identifiable callbox can make it easier for employees, visitors, delivery drivers, contractors, and other personnel to locate the communication point when they need assistance.

Ritron also offers the Q-Series in a black enclosure, but the RQX-411-QGRN configuration uses the high-visibility green housing.

Rugged Polycarbonate Construction

The Q-Series uses a gasket-sealed, high-impact molded polycarbonate enclosure designed for professional environments.

The callbox is also designed to resist tampering and vandalism and includes an internal antenna and a long-life machined aluminum push-to-talk button.

Ritron specifies splash resistance and shock and vibration performance based on its testing. The specified operating temperature range is -20°C to +55°C (-4°F to +131°F), with battery performance affected by low temperatures.

Battery or External Power

The RQX-411 can be deployed as a stand-alone callbox using three D-cell alkaline batteries, making it useful in locations where running power wiring is inconvenient.

For installations requiring continuous operation, the callbox can also use an external 12VDC power source. With external power, the RQX-411 can transmit at up to 2 watts. When operating from three D-cell batteries, transmit power is specified at 700 mW.

For battery-only applications, Ritron recommends enabling the automatic turn-off feature for optimal performance.

Clear Audio for High-Noise Environments

Industrial facilities, loading docks, garages, manufacturing areas, and construction sites can be noisy. The Q-Series incorporates an adjustable-volume, high-audio-output speaker designed to make incoming radio communications easier to hear in these environments.

This allows the callbox to function as a practical communication point in locations where standard low-volume communication devices may be difficult to hear.

Analog Signaling Support

The RQX-411 supports several analog signaling functions, allowing it to work within compatible analog radio communication systems.

Supported signaling includes:

• CTCSS Encode/Decode

• DCS Encode/Decode

• DTMF Encode/Decode

• SelCall Encode/Decode

• 2-Tone Decode

These functions can help organizations configure the callbox to work with their existing compatible analog radio communication setup.

PC Programmable

The Q-Series callbox provides field-programming capabilities for selected parameters and supports full PC programming through its internal USB connection.

Ritron offers the RQX-PCPK-1 PC Programming Kit, as well as programming software and a dedicated programming cable.

This provides organizations with flexibility when configuring frequencies and other supported radio parameters.

Easy Installation Without Communication Wiring

One of the major advantages of the Q-Series design is its wireless radio communication.

Ritron states that the callbox can be deployed without trenching or the construction costs normally associated with running communication wiring to remote locations.

The standard flange mounting-hole pattern supports installation, while optional mounting accessories are available for different mounting requirements.

Common Applications

Security and Gated Entrances

Install the RQX-411 at a gate or entrance so visitors, employees, and delivery personnel can contact security staff using the organization's compatible UHF radio system.

Manufacturing Facilities

Production areas, maintenance departments, and plant floors can use callboxes as fixed communication points for employees who may not carry individual radios.

Warehousing and Distribution

The RQX-411 can provide communication access at loading docks, receiving areas, storage facilities, and other locations throughout a warehouse or distribution operation.

Construction

Construction sites can use callboxes at entrances, remote work areas, hoists, staging locations, or other points where workers need access to the site's radio communication system.

Retail and Convenience Stores

Retail facilities and convenience stores can install a callbox at service areas, entrances, loading locations, or other points where staff need a dedicated communication station.

Education

Schools, campuses, and educational facilities can use fixed radio callboxes to provide communication points around buildings, entrances, maintenance areas, or other designated locations.

RQX-411 vs. RQX-417

The RQX-411 and RQX-417 are both UHF Q-Series callboxes operating in the 450–470 MHz band, but they are intended for different feature requirements.

The RQX-411 is the standard Q1-series UHF callbox. The RQX-417 is the Q7-series UHF model with additional advanced functions, including a built-in relay, stored voice-message capability, and sensor switch inputs.

For a straightforward wireless analog communication point, the RQX-411 provides the standard Q-Series configuration. Organizations requiring relay control, voice messages, or sensor inputs can consider the Q7-series RQX-417 instead.
