Alpha Communications T1240 Intercom Transformer 12V 40V

Product Description

The ALPHA COMMUNICATIONS T1240 is a dual-output transformer designed to power intercom systems requiring both 12-volt and 40-volt AC outputs. Transformers of this type serve as the power foundation for intercom control panels and door station accessories, stepping down standard line voltage to the low-voltage levels these systems require. Licensed electricians and low-voltage technicians install this component as part of intercom system commissioning or replacement service. The T1240 is sold as an individual unit and is categorized as an intercom accessory within the ALPHA COMMUNICATIONS product line.

This transformer is suited for residential and light commercial intercom installations where dual-voltage power supply is required. It is typically mounted near the intercom control panel or in a nearby electrical enclosure, providing clean, stable low-voltage power to the system. Installers working on intercom system upgrades or repairs will find this transformer applicable when the original power supply has failed or when a system is being newly wired.

Key Features

• Dual output: 12-volt and 40-volt AC for intercom system compatibility
• Designed as a direct intercom accessory for panel and door station power
• Single-unit packaging suitable for one-for-one replacement installs

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements. Disconnect and lock out all power to the intercom system and panel before removing the existing transformer or making any wiring connections. Mount the transformer securely in a dry, protected location away from direct exposure to moisture. Verify output voltage with a meter after installation before restoring power to the intercom system.
