Alcad 2-Wire Phonic Group Series 961

Function of the speaker unit in 2-wire systems

The sound group is the element in charge of managing audio and communication logic of the electronic intercom system. In the design of the GRF-302 , ALCAD separates this module from the speaker and microphone, allowing safer and neater installation inside the street sign.

This solution is especially useful in access to buildings , where the outer plate is exposed to frequent manipulations and where it is critical to protect the main electronics.

Practical Applications of the GRF-302 2-wire Audio Group

1. Street sign at access to residential building
In a 2-wire ALCAD electronic intercom installation, the GRF-302 is installed at the bottom of the entrance panel's flush-mounted box, while the speaker and microphone are located at the front. This improves the durability of the system and facilitates future maintenance tasks.

2. Replacement of audio group in existing systems
In maintenance or repair work, the GRF-302 allows you to replace only the door speaker module without having to replace the rest of the entrance panel, maintaining compatibility with the ALCAD 2-wire system already installed.
