Fire Alarm and Security Systems
Building and Campus Wide Communication
Simplex Fire Alarm Networks communicate information among distributed Simplex fire alarm control panels. Systems may becomposed of similar capability panels sharing information, or specific nodes may be added to perform dedicated network functions. Illustrations on the following pages provide a sample of the variety of fire alarm network applications, multiple topologies and connectivity options.
For non-Simplex panels, a network system integrator can be used to connect equipment to the network using optically isolated inputs and relay contact outputs.
Network communications among system fire alarm con trol panels provides
- Support for network emergency voice broadcasts and centralised command centre operations
- Multiple network loops for campus and other high panel quantity applications
- Network-wide initiation of alarm silence, acknowledge, and reset; and investigation of status and details of system points and point lists
- Network-wide synchronization of notification appliances
- Distributed system operation to ensure excellent survivability; during a communications fault condition, network nodes remaining connected will regroup and continue communicating
- Flexible network annunciator options such as, TrueSite Workstations, Network Display Units (NDU) and NDUs with Voice Command Centre
- Use of InfoAlarm Command Centre equipped nodes to provide increased network information display capability
- Network level command and control provides manual point control for on/off or disable/enable, as well as gathering specific point detail
