TJ201 is a wall-mounted fire telephone extension handset used with ANWETECH fire telephone panels (TJ101 / TJ102). It provides a dedicated communication point for firefighters and control room operators during fire and emergency situations.
【Product Description】
TJ201 wall-mounted fire telephone extension is part of the ANWETECH two-wire fire telephone system together with TJ101 / TJ102 fire telephone panels and TJ301 fire telephone jacks. It uses a non-polar two-wire bus powered from the panel and allows firefighters to establish instant voice communication with the control room simply by lifting the handset.
The compact wall-mount enclosure is designed for corridors, staircases, refuge areas and fireman lift lobbies. With very low standby current and robust housing, TJ201 is suitable for long cable distances and continuous 24/7 operation in high-rise buildings and complex projects.
