D+H RZN 4416-M Smoke and Natural Ventilation Control Panel

Overview

The D+H RZN 4416-M is a 24 V DC smoke and natural ventilation control panel for larger window automation applications requiring increased actuator capacity. It is suited to projects requiring fail-safe operation in fire mode using dedicated fire alarm inputs and monitored 72-hour battery backup. In addition to smoke control, it also provides day-to-day natural ventilation functions where windows or louvres are operated by local controls and can be interfaced with weather sensor and/or BMS inputs.

The RZN series of smoke control panels is certified to EN 12101 / ISO 21927 and includes monitored 72-hour fail-safe battery backup. Where required, the system can close the windows on loss of mains power, remain ready during the 72-hour backup period, and then drive the windows to the required smoke ventilation position if a fire signal is received. The batteries are sized to provide this function with additional safety capacity. To ensure these life-safety systems function as designed, they must be inspected, tested and maintained by a competent service provider in accordance with the manufacturer’s requirements and the project maintenance regime.

EBSA can assist with actuator selection, control panel selection, wiring coordination and commissioning support to confirm that the system is suitable for the project requirements. EBSA also provides inspection, testing and maintenance services for both new and existing D+H Mechatronic smoke and natural ventilation systems throughout New Zealand.

At-a-glance

Best suited to

• Larger smoke and natural ventilation window automation systems.
• Projects requiring smoke ventilation control with day-to-day natural ventilation operation.
• Natural ventilation systems where automatic close on loss of mains power is required.
• Systems requiring up to 16 A total drive current.
• Systems requiring up to 3 ventilation groups and 2 fire zones / lines.
• Window or louvre automation controlled by local wall switches and fire alarm interface.
• Weather-protected systems using rain and/or wind sensor input.
• Projects where a higher-capacity RZN smoke control panel is required and a larger modular CPS-M panel is not required.

For larger or more complex systems: For additional zones, higher total drive current, BMS integration, complex cause-and-effect logic or project-specific smoke control sequencing, EBSA can assist with selection of a custom CPS-M control panel.

Typical system arrangement

Technical notes for specifiers

• This is a smoke and natural ventilation control panel.
• Confirm project-specific smoke control requirements with the fire engineer, mechanical engineer and relevant approval authority.
• Confirm total actuator current before selection.
• Confirm the number of windows, actuator type, ventilation groups and fire zones / lines.
• Confirm fire alarm interface requirements and required cause-and-effect operation.
• Confirm weather sensor and day-to-day natural ventilation control requirements.
• Confirm whether BMS or other third-party controls are required.
• Where more complex smoke control functionality, BMS integration or custom zoning is required, consider a custom CPS-M panel.

Notes for builders, electrical contractors and aluminium joiners

Builder / electrical contractor

• Allow for power supply requirements based on the final panel configuration.
• Allow cabling between panel, switches, sensors, fire alarm interface and actuators.
• Confirm whether fire-rated cabling or fire-rated cable pathways are required.
• Confirm final panel location with EBSA.
• Confirm fire alarm interface, manual control locations and weather sensor locations before wiring.
• Confirm commissioning responsibilities before installation.
• Allow for the selected housing size and mounting location.

Architectural aluminium joiner (drive compatibility)

• Confirm drive compatibility before fabrication.
• Allow for drive fixing points and cable pathways in the window frame, where possible, to conceal cables.
• Contact EBSA to select the correct bracket set for your window.
• Confirm whether EBSA is supplying drives only or a full turnkey solution.
• Confirm what colour drives are required and whether a standard 2.5 m cable tail is suitable for your windows.

Compatible products

Compatible with:

• D+H 24 V chain drives.
• Fire alarm interfaces.
• Low-level BMS interfaces.
• Rain sensors.
• Wind sensors.
• Wall switches.
• Natural ventilation accessories.

Consider instead:

• GVL natural ventilation panel — where natural ventilation only is required and smoke ventilation functionality is not required.
• Smaller RZN smoke control panel — where lower total drive current is required.
• CPS-M modular control panel — customised to each project, with flexible zoning for natural ventilation, smoke control, stand-alone logic or BMS interfacing.

About CPS-M: EBSA CPS-M panels are custom designed as project-specific control solutions using D+H modular components. The process begins by establishing the project scope, control philosophy and functional requirements, which are then developed into shop drawings and wiring schematics. Once approved, the panel is built by EBSA to suit the agreed design and control logic.
