Potter's SignaLink Bridge Wireless Supervisory System can monitor any dry-contact switch such as tamper or flow switches and transmit their status wirelessly to any fire alarm panel. SignaLink Bridge uses a wireless transmitter, installed with the switch being monitored, and a wireless receiver, installed with the fire alarm panel, to fully monitor the switch's state. With a maximum range of 800' between devices and optional wireless repeaters, SignaLink Bridge can supervise dry-contact switches across even the largest projects without trenching, destruction of sensitive architecture, or costly wiring.
