The TCM-8 Telephone Communications Module provides eight Firefighter/Warden Telephone circuits. The Firefighter/Warden Telephone circuits can be configured as 8 Style Y (Class B) circuits or 4 Style Z (Class A) circuits. Each circuit can communicate with Firefighter Phone Jacks or up to three 2-wire Warden Stations. The telephone circuits are monitored and controlled by the COM-2 Communications card in the DAN-7.
