Study Notes

S-95 FDNY Test Overview

S-95 certificate holders are authorized to perform visual inspections on smoke alarms only.
Fire alarm systems primarily function to alert tenants and signal the FDNY via a central station about fire incidents.

Fire Alarm Control System

Fire Alarm Control Panel (FACP) is crucial for monitoring inputs and controlling outputs through various circuits, activating audible and visual alarms.

Signal Types

There are three main signal types:
- Fire Alarm Signals: Initiated by manual pull stations, smoke detectors, or water flow switches during a fire.
- Supervisory Signals: Indicate abnormal conditions of monitored systems requiring attention.
- Trouble Signals: Highlight failures like battery or AC issues, or circuit malfunctions.

Alarm Management

Alarm Silence Switch: Used to silence alarms during investigations and should not be reset until confirmed by FDNY.
System Reset Switch: Resets the fire alarm system after conditions are cleared, usually not effective for trouble conditions.

Maintenance and Testing

Smoke detectors need cleaning biannually and annual testing for smoke entry.
Primary power for fire alarm systems should not exceed 277/480 volts. Secondary power must be independent from batteries.

Detection Devices

Smoke Detectors: Detect both visible and invisible combustion particles, outperforming heat detectors in speed.
Heat Detectors: Two types:
- Fixed-temperature: Activated by preset temperature; typically require replacement after activation.
- Rate-of-rise: Sensitive to rapid temperature increases and usually restore after activation.

Specialized Detectors

Ionization Detectors: Use ionization to sense smaller smoke particles.
Photoelectric Detectors: Detect smoke by light obscuration or scattering, effective in high-smoke scenarios.
Multi-criteria & Multi-sensor Detectors: Utilize multiple sensors for enhanced detection capabilities, able to signal alarms based on combined stimuli.

Fire Classes and Extinguishers

Class A Fires: Involve solid combustibles like wood and paper; common in dry areas.
Class B Fires: Involve flammable liquids; frequent in kitchens and maintenance.
Class C Fires: Involve electrical components.
Class D Fires: Involve reactive metals such as magnesium and titanium.
Class K Fires: Concern cooking oils and fats.

Fire Extinguisher Protocols

Monthly checks of portable fire extinguishers are mandatory.
Extinguishers must be evaluated for charge status, placement, tampering signs, and physical integrity.

Documentation and Logkeeping

Alarm logs must include detailed information on alarms, maintenance, and system statuses, retained for three years.
Daily log entries should capture essential information like certificate holder's details and times of events.

Additional Protocols

Prior notification of the FDNY is necessary when taking fire alarm systems offline to avoid unnecessary dispatches.
Out-of-service signage must be displayed and maintained by the impairment coordinator.

Inspection and Maintenance Requirements

Routine maintenance must be carried out by designated FDNY-approved individuals to ensure operational readiness and compliance.
