FAQs
Can I use this power supply for non-Gira intercoms?
No, this power supply is specifically engineered for Gira video intercom bus systems and may not be compatible with other manufacturer standards.
Does this unit require a separate transformer?
No, it is a self-contained unit that connects directly to the 230V AC mains supply.
What happens if there is a short circuit on the bus?
The unit is short-circuit proof, meaning it is designed to detect the fault and protect itself from permanent damage.
Can it be installed in a garage or basement?
Yes, provided the location is dry and protected, as the unit carries an IP20 rating which offers no protection against water or moisture.
What is the maximum number of devices it supports?
The unit is rated to support up to 18 participants in the bus system.
Troubleshooting
Intercom system has no power
Verify that the 230V AC input is active and the circuit breaker is set to the ON position. Check all terminal connections for looseness.
Door strike fails to trigger
Test the continuity of the wiring between the power supply door opener terminals and the electric strike itself. Ensure the power supply is receiving adequate bus communication.
System experiencing signal interference
Check that the bus wiring is properly shielded and does not run parallel to high-voltage lines for long distances.

Setup, Compatibility & Care
Installation of the 128800 must be performed by a qualified electrician in accordance with local building and electrical codes. To install, snap the unit onto a standard 35mm DIN rail within the distribution cabinet. Ensure that the power supply is isolated from the 230V mains during the connection of the bus lines and door strike wiring. The unit does not require active cooling, but ensure adequate ventilation within the cabinet to maintain optimal operating temperatures. Regularly inspect the terminals for tightness during annual maintenance to prevent loose connections, which can lead to intermittent system performance.
