Firefighter Phone Module

The Firefighter Phone Module (P/N 24-135) is intended to monitor and control a loop of firefighter phones.

It has the ability to differentiate between normal, off-hook, and trouble conditions.

When taken off-hook, a phone will immediately receive a ringing tone, and the panel will receive an off-hook indication.

The panel can then connect that off-hook phone to the main riser for the system.
