Consilium – NS-DRP DOOR RELEASE SWITCH (N1781)

The Consilium Salwico NS-DRP (N1781) provides reliable manual control of door release functions in harsh and demanding environments. Designed for wall-mounted installation, the switch combines robust construction with IP55 ingress protection, making it suitable for marine, offshore, and industrial applications where dust, moisture, and challenging environmental conditions are present.

Built to withstand tough operating environments, the NS-DRP helps maintain dependable door release operation as part of a fire alarm or safety system. Its durable enclosure protects internal components against dust ingress and water spray, ensuring reliable performance in exposed installation areas.

Unlike spring-return switches, the NS-DRP features a maintained contact mechanism. Once activated, the switch remains in the closed position until personnel manually return it to the open position. This ensures that the connected door release function remains active until deliberately reset.
