Fire Alarm & Sprinkler System

Flashcards covering key concepts related to fire alarm and sprinkler systems, their components, and functionality.

Fire Alarm System

A system that detects fire or its effects, notifying occupants, the surrounding area, the fire department, and controlling fire alarm components.

Sequence of Operation

An outline developed for the operations of fire systems based on active fire alarm devices.

PIV (Post Indicator Valve)

A valve designed to shut off water to the building during a fire, indicating status to the fire alarm panel.

Detector Check

Monitors water flow in the fire sprinkler system and incorporates a backflow device.

Fire Sprinkler Riser

Includes a stainless-steel pipe riser in the fire riser room, which features water pressure gauges and water flow switches.

Main Lines in Fire Sprinkler Systems

Large pipes that carry water from the fire sprinkler riser throughout the building.

Branch Lines in Fire Sprinkler Systems

Pipes that connect to the main line and distribute water over the space.

Fire Sprinkler Heads

Devices designed to release water in response to heat, available in various designs and temperature ratings.

Temperature Ratings of Fire Sprinkler Heads

Classified by the size of the glass bulb and the operating temperature that triggers activation.

Electrical Supervision in Fire Detection

Monitoring that ensures the integrity of circuit systems and automatically transmits signals.
