The SPECO KE-20DR NOS School Station Transistor Security Intercom is a versatile and reliable communication system designed specifically for educational institutions. This intercom system is equipped with a number of features that ensure effective and secure communication between various areas of a school campus.
The KE-20DR NOS intercom features a robust transistor design, which makes it durable and capable of withstanding the demanding environment of a school setting. It comes with a total of 16 call buttons, each of which can be programmed to connect to specific locations within the school. These call buttons are conveniently labeled with alphanumeric characters for easy identification and use.
One of the standout features of this intercom system is its ability to support both one-way and two-way communication.

The system is easy to install and can be connected to a public address (PA) system for even greater reach.
Another useful feature of this intercom system is its weatherproof design, which allows it to be installed outdoors without the risk of damage from the elements. This makes it an ideal solution for larger schools with extensive campuses.
In terms of security, the KE-20DR NOS Intercom comes with a number of measures to ensure that only authorized individuals can access the system. These measures include a lockout feature that prevents unauthorized use of the call buttons, as well as a password protection system that requires a code to be entered before announcements can be made.
Overall, the SPECO KE-20DR NOS School Station Transistor Security Intercom is a high-quality communication system that offers a range of features to help schools effectively manage communication between various areas of their campus. Its robust design, ease of use, and advanced security features make it an excellent investment for any educational institution.
