What is a Firefighter's Telephone System?

ທີ່ໃຊ້ເວລາ: 2021-05-18

ແມ່ນຫຍັງ? Firefighter's Telephone System?

1.Firefighter's Telephone System

A firefighters telephone system is a special telephone system that allows firefighters to talk to each other inside a building when they can't use their radios. In a large building, so they can talk to each other while battling fires, firefighters use their two-way radios. But when the radios just don't work, the firefighter's phone system is the next best way to communicate.

2.POTS

The whole firefighter's phone system is a stand-alone, Plain Old Telephone System (POTS) - just like the dialup system for the phone company. The main difference between ma-belle and the firefighter's phone system is the firefighter's phone uses no bell ringing voltage, no dial-tone, and you can't dial-up any other building.

Instead of ringing, the phone at the fire command center just detects another phone plugged in and sounds an alert tone until answered.
