Edwards 3-FTCU Firefighter's Telephone Control Unit (NEW)
The 3-FTCU Firefighter's Telephone Control Unit (FTCU) is designed to used in conjunction with the 3-ASU Audio Source Unit (ASU), mounted on a common chassis. The two units in combination provide the main telephone riser, the Audio Source Unit with Firefighter's Telephone (ASU/FT). The telephone circuit requires a separate hardwired riser and is not multiplexed over the network audio riser. The riser is supervised by the URSM. The ASU/FT requires one chassis space within an enclosure. The 3-FTCU features the following switches: Connect (link incoming to master headset), Review Pending (scroll through incoming pending calls), Acknowledge (silence in-call buzzer), Disconnect (remove a connected phone from system), and Review Connected (scroll through active connected calls).
