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

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

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.
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-24V013P — 24V Proportional Control Actuator

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.
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.

How does the actuation cable attach to the MRC?

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