The 7600 annunciator series from Dortronics Systems Inc. is a modular system expandable in four- and eight-zone increments with custom panels available for console or rack mounting in zone increments. The series can be configured to provide monitoring and control of more than 100 doors/zones. Zone status is displayed with tri-state LEDs and, regardless of alarm status of the zone, the position of any door is always indicated. Compatible with most NFPA-approved delayed egress systems, the 7600 annunciator series can remotely unlock doors from the console, perform authorized entry and monitor egress operations via an access control system or REX device.
