Simplex Fire Alarm Systems
Topaz Fire Systems Private Limited offers Simplex Fire Alarm Systems. A ring signal on a remote firefighter telephone indicates that a call request is initiated and a hold signal indicates that a connected line has been deselected. Telephone circuits are supervised for open and short circuits and too many telephones connected. The master telephone is supervised for cord integrity. Degraded mode allows remote telephones to remain connected to each other in the event of a communications loss.
