MRC Actuation

The open-and-close action of the Zazz MRC can be controlled in several ways: failsafe electrical actuators, a proportional failsafe electrical actuator, or a manual actuation cable.

ASR-UV013 — Universal Failsafe Actuator

Stacks Image 2798
The new Universal Voltage Control Actuator adds the ability to remotely operate the MRC Louver Air-Foils™ from the fully opened to fully closed positions. This actuator features the same fail-safe closure as our other MRC actuators.

If your vessel's fire system activates and opens the closure holding circuit, the Universal MRC Failsafe Actuator loses power. This activates a powerful spring return, firmly closing the attached MRC. Closing the MRC creates an ABS-compliant weather closure, and helps contain extinguishant inside the protected space.

To re-open the attached MRC, power must be restored to the actuator. The motorized rotary actuator will then re-wind its spring, bringing the attached MRC into the open position.

Actuation of the MRC can be done remotely, with longer custom cables suited to your specific application.

This actuator uses an extremely high torque, maintenance-free, brushless motor with very low current draw requirements. In the event of power or control signal loss, each actuator includes an integrated tool to allow it to be opened manually and locked in whatever position is required. Mechanical position indication is also provided. A non-metallic NEMA 4/IP66 junction box is provided for electrical power connections to internal DIN rail screw terminals.

Exterior enclosure is anodized marine grade aluminum with stainless steel hardware. Internal MRC cable adjustments are simple and straightforward when the safety cover is removed during installation.

ASR-UV013S — Universal Failsafe Actuator w/ Position Switch

Stacks Image 2733
Our Universal Voltage Control Actuator with Position Switches adds the ability to allow the MRC Louver Air-Foils™ to be remotely operated from the fully opened to fully closed condition. This actuator retains the same fail-safe closure upon power loss as our other MRC actuators, but also provides open and closed position switches for remote indication. That means you’ll be able to wire this model to remote indicator lights or an alarm system.

The Actuator uses an extremely high torque brushless motor with very low current draw requirements and is maintenance-free. In the event of power loss, each actuator includes an integrated tool to allow it to be opened manually and locked in whatever position is required. Mechanical position indication is also provided. A non-metallic NEMA 4/IP66 junction box is provided for electrical power connections to internal DIN rail screw terminals.

ASR-24V013P — 24V Proportional Control Actuator

Stacks Image 2801
The new Proportional Control Actuator allows the MRC Louver Air-Foils™ to be positioned between the fully opened and fully closed positions. This actuator retains the same fail-safe closure upon power loss as our other MRC actuators, but allows a separate 2-10VDC input signal to adjust the position of the MRC Louver Air-Foils™. In addition, an independent 2-10VDC output position signal is also integrated to allow use of a feedback or monitoring system.

This actuator uses the same maintenance-free brushless motor as our Universal Actuator. In the event of power or control signal loss, each actuator includes an integrated tool to allow it to be opened manually and locked in whatever position is required. Mechanical position indication is also provided. A non-metallic NEMA 4/IP66 junction box is provided for electrical power connections to internal DIN rail screw terminals.

MRC-MCK00300 — Manual Actuation Cable

Stacks Image 2795
Our Manual Actuation Cable features a locking T-handle with stainless hardware. Standard cable length measures up to 25 feet, but longer lengths are available. The locking T-handle can be installed in an interior or exterior location. A red anodized aluminum disc makes the T-handle easy to identify in dim or cramped machinery spaces.

How does the actuation cable attach to the MRC?

The actuation cable is mounted to the rear of the MRC unit using stainless steel hardware.

The end of the cable is then attached to the rear of one of the MRC Air-Foils using a stainless steel clip assembly.
