Study Notes
Fire Alarm Systems Overview
- An approved central station company is certified by the FDNY.
- A plenum is the area that allows air circulation between ceilings and the floor above.
- Unnecessary alarms indicate that the alarm functioned correctly; however, a department response is not required.
- Unwarranted alarms result from poor installation or maintenance.
Regulatory Changes
- The new fire code adopted in July 2008 significantly altered supervision requirements for fire alarm systems.
S-95 COF Holder Responsibilities
- Duties performed by an S-95 holder are limited to visual inspections only.
Fire Alarm System Functions
- The primary function of a fire alarm system is to alert occupants and relay fire signals to the FDNY.
- A fire alarm control panel processes signals from initiating devices and activates appropriate alerts.
Signal Types
- A fire alarm signal indicates detectable fire presence.
- A supervisory signal denotes an abnormal state in devices being monitored.
- A trouble signal shows that the system, transmitter, or communication path is partially or fully inoperable.
Signal Management
- Central station trouble signal handling should occur within four minutes of receipt.
- The FDNY does not respond to supervisory or trouble signals.
Alarm Conditions
- Do not silence audible and visual alarm devices until the fire alarm condition is confirmed by FDNY personnel.
- Smoke detectors require cleaning every six months by certified COF holders.
- Any abnormal conditions must be documented in the logbook.
Power Specifications
- Fire alarm primary power must not exceed 277/480 volts.
- Batteries cannot serve as a standalone power source; a secondary power source is necessary.
Maintenance Requirements
- When smoke detectors notify the fire alarm control panel of maintenance needs, cleaning must occur within one week.
- Ionization detectors utilize an ionization chamber to detect electrically charged particles (ions).
Detector Types and Functions
- Photoelectric detectors excel at detecting smoky fires, such as smoldering materials.
- Projected beam-type detectors must remain free from opaque obstacles and designed to prevent nuisance alarms.
- Multi-criteria detectors use multiple sensors for a single alarm signal, while multi-sensor detectors can generate multiple alarms.
HVAC and Air Sampling
- Dust smoke detectors deactivate a building's HVAC system and adjust airflow.
- For air sampling type detectors, maximum air sampling transport time should not surpass 120 seconds.
- Trouble signals trigger if airflow deviates from specified ranges.
Alarm Output and Response Times
- Maximum allowable time for alarm functions to initiate after smoke detector activation is ten seconds.
- Rate of rise heat detectors do not require replacement following alarm activation.
Specific Equipment Requirements
- Carbon monoxide detectors are mandatory in buildings with fossil-fuel-burning equipment.
- The fire alarm control panel can only be reset under a fire department representative's direction.
Maintenance and Inspection Protocols
- Single action stations are typically located indoors.
- The fire alarm system cannot be reset at manual pull stations once activated.
- A certified plumber can maintain residential sprinkler systems if there are less than 30 sprinklers.
Inspection Standards
- FDNY inspects all subsystems for approval letters.
- In larger buildings, fire annunciators may work in conjunction with smoke purge and communication systems.
- The general alarm method activates all devices in the building; selective methods activate those on the alarm floor and adjacent floors.
Testing Frequencies
- Two-way communication systems require testing every six months.
- Unmonitored fire command centers must be inspected weekly, while monitored centers require annual inspections.
- Daily visual inspections are highly recommended by the FDNY.
Alarm Management Documentation
- An alarm logbook is maintained at the building's fire alarm control panel, and it should be bound.
- The logbook comprises daily entries, system offline notes, activated alarm records, and notification entries.
