Isonas ACC-IRS-4700 In-rush Suppressor Panel Accessory

Product Description

The ISONAS ACC-IRS-4700 is an in-rush suppressor designed for use with access control panel installations. In-rush suppressors limit the high transient current spike that occurs when inductive loads such as electric strikes, magnetic locks, or solenoid-operated devices are energized or de-energized. Without suppression, these current spikes can damage relay contacts, degrade control board components, and shorten the service life of connected hardware. The ACC-IRS-4700 is installed by low-voltage security and access control technicians as part of a complete panel accessory configuration.

This suppressor is suited for panel accessory applications where inductive locking or electrified door hardware is controlled through relay outputs. It is typically installed directly across the load terminals of an electric strike or magnetic lock circuit. Use in commercial and light-commercial access control systems where relay contact protection and signal integrity are required. Installation alongside ISONAS access control panels is the primary application context.

Key Features

• Suppresses in-rush and back-EMF transients generated by inductive door hardware loads
• Protects relay contacts and control board outputs from transient voltage damage
• Compact form factor suited for installation inside or adjacent to access control panels
• Sold as an individual unit, compatible with panel accessory configurations

Compatibility

Designed as an OEM-style accessory for ISONAS access control panel installations where in-rush suppression is required on inductive load circuits.

Installation Notes

Installation should be performed by a licensed low-voltage technician familiar with access control wiring practices. De-energize the panel and disconnect power before making any wiring connections. The suppressor is typically wired directly across the inductive load terminals. Follow applicable local codes and the panel manufacturer wiring guidelines when integrating panel accessories.
