Quam Nichols Company CIS4/25 Intercom Station 25 Ohm

Product Description

The QUAM NICHOLS COMPANY CIS4/25 is a vandal resistant intercom station rated at 25 ohms, designed for use in audio intercom systems with AV integration capability. Built to withstand physical abuse in high-traffic or unsecured locations, this unit delivers reliable two-way communication where standard intercom hardware would be vulnerable to damage. It is sold as an individual unit and is typically installed by low-voltage technicians or communications contractors working on commercial or institutional intercom infrastructure.

The CIS4/25 is suited for installations where durability is a primary concern, including schools, correctional facilities, industrial facilities, and entry-control points. It integrates into analog audio intercom systems with AV integration support, making it appropriate for both standalone intercom runs and larger coordinated communication setups. The vandal resistant construction addresses environments where intercom stations face intentional or incidental physical stress.

Key Features

• Vandal resistant construction for high-risk or high-traffic environments
• 25 ohm impedance rating for compatibility with matched analog intercom systems
• Supports AV integration in analog audio intercom architectures
• Single unit (EA) packaging for straightforward replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-install component for analog audio intercom systems with AV integration support requiring a 25 ohm impedance intercom station.

Installation Notes

Installation should be performed by a licensed low-voltage or communications technician in accordance with applicable local codes and NEC low-voltage wiring requirements. De-energize the intercom system and disconnect power to the control panel before removing or installing any station. Verify impedance matching between the station and the intercom controller before final connection. Use appropriately rated low-voltage cable and secure all terminations before restoring power.
