Fire emergency communication system

Introduction to the equipment

________________________________________

Underground wireless communication system, mainly clusters and conventional communication equipment in the subway, underground or other shielding environment, when the two-end equipment can not contact, the form of communication equipment, so as to ensure the smooth communication of two-end communication equipment. At the same time, underground emergency dynamic launch system contact, but also in practical applications, for unified command, cluster equipment and the general mode of the external network consistency or multi-frequency, off-frequency simultaneous work to achieve unified command. The effect of hetero-frequency heteronets to contact and talk to each other. Supervision report with quality supervision of fire-fighting equipment

The main features

________________________________________

1. Shielding environment, internal and external voice transit, no need to write frequency settings.

2. When the cluster equipment and the conventional equipment are under unified command, the communication between the cluster and the conventional equipment is connected, and the frequency of operation is not limited. Hetero-frequency networks are interconnectable and clearly intercomable.
