Edwards Signaling 3005-N Recessed Roller Plunger Switch

Product Description

The EDWARDS SIGNALING 3005-N is a recessed roller plunger switch designed for normally closed operation in fire alarm and life safety signaling systems. The recessed plunger design allows flush or semi-flush mounting in door frames, panels, or enclosures, where the roller actuator makes contact with a door or panel surface to change switch state. This type of switch is commonly installed by fire alarm technicians and low-voltage system integrators as part of supervised circuit loops that monitor the open or closed status of access points, control panels, or equipment enclosures.

The 3005-N is suited for commercial and light industrial fire accessory applications where a compact, recessed form factor is required. It is sold as an individual unit and is appropriate for new installations as well as service replacement in existing fire alarm or signaling panel assemblies. Technicians working on supervised control loops will find this switch compatible with standard normally closed circuit architectures used in fire accessory wiring.

Key Features

• Normally closed contact configuration for supervised loop monitoring
• Recessed roller plunger actuator for flush or semi-flush installation
• Compact form factor suited for door frames and equipment enclosures
• Sold individually for targeted replacement or new installation use

Compatibility

Designed as an OEM-style replacement or new-install component for fire alarm signaling systems requiring a recessed roller plunger switch in a normally closed configuration.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified low-voltage contractor in accordance with NFPA 72 and local authority having jurisdiction requirements. De-energize and supervise the affected signaling circuit before removing or installing the switch. Verify switch actuation travel and roller contact alignment before restoring the circuit to service.
