Sdc - Security Door Controls 463NU Piezo Electric Push Button

Product Description

The SDC - SECURITY DOOR CONTROLS 463NU is a piezoelectric push button designed for access control and egress applications. It operates on 12 or 24 volt systems, making it compatible with a wide range of low-voltage door control setups. Piezoelectric buttons use solid-state switching with no moving parts, which reduces mechanical wear and supports reliable long-term operation in high-traffic environments. This type of device is typically installed by access control technicians, electricians, and security integrators working on commercial or institutional door hardware projects.

The 463NU is suited for use as an exit or request-to-exit button in access-controlled door systems. It fits into applications where a momentary signal is needed to release an electric strike, magnetic lock, or door control panel. Typical installations include office buildings, healthcare facilities, and secured entry points where code-compliant egress hardware is required. The dual-voltage rating at 12 and 24 volts gives installers flexibility when integrating with existing panel infrastructure.

Key Features

• Dual-voltage operation at 12 or 24 volts suits a wide range of low-voltage access control panels
• Piezoelectric switching mechanism with no mechanical moving parts for extended service life
• Sold as a single unit for straightforward replacement or new installation
• Designed for exit device and push button applications in commercial door hardware systems

Compatibility

Designed as an OEM-style replacement or new-installation piezoelectric push button for low-voltage access control and egress systems operating at 12 or 24 volts.

Installation Notes

Installation should be performed by a licensed electrician or certified access control technician in accordance with applicable NEC low-voltage wiring requirements. Disconnect and de-energize the access control panel before wiring the button to prevent damage to panel components. Verify system voltage is 12 or 24 volts DC before connecting to avoid device damage. Follow the door hardware manufacturer and local AHJ requirements for egress button placement and mounting height.
