[Edit] Basic Configuration
Honeywell DeltaNet FS90 fire alarm control panel. Fire Alarm Control Panel: This component, the hub of the system, input and system integrity monitor, control output and relay information.
Main power supply: common non-GM 120 or 240 volt AC power from commercial power companies. In the non-residential applications, specifically for the branch circuit fire alarm system and its components. "Dedicated branch circuit" should not be confused with "individual branch circuit", which provides the energy for a single device.
Secondary (backup) power supply: This component, sealed lead-acid batteries commonly used in emergency or other sources including the alternator, is used to provide main power failure in the energy.
Boot device: This component of the fire alarm control unit as input, and can be manually or automatically. Examples would be like a smoke detector or pull station equipment.
Fire alarm in the San Francisco streets. Notification device: the components used in fire alarm systems or other stored energy source to provide energy, this action is needed, usually proximate to evacuate people. This is a flashing light, strobe light, mechanical and electrical horn, horn, or combinations of these devices.
