S-95 FDNY TEST STUDY GUIDE QUESTIONS AND ANSWERS 100% PASS What Can A S95 Holder do? Only visual inspections on smoke alarms Primary Purpose of Fire Alarm Systems on a premise is to warn tenants and transmit signals indicating a fire condition to the FDNY aka Central station Fire Alarm Control Panel (FACP) Monitors inputs and controls output through various types of circuits.The Panel activates the building audible and visual device connected to the fire alarm (horn/strobes) Three Types of Signals Fire Alarm Signal, Supervisory Signals, and Trouble Signals Fire Alarm Signal Manual fire alarm pull station, smoke detector, water flow switch in the presence of a fire or fire signature. Supervisory Signals Signals which Indicate that a system or device being monitored has been compromised or is in an abnormal state. Will audibly and visually annunciate at the FACP to indicate the condition needs to be investigated and corrected. The FACP will also send a signal to an FDNY approved central station. Trouble Signals Battery failure, AC failure, ground fault, open or short circuit on a wire, phone line failure, internal component failure. Alarm Silence Switch or Button Is used to silence the building audible and visual devices after evacuation is complete while the source of alarm is being investigated. Never reset the fire alarm system until the condition is verified by the FDNY personnel. System Reset Switch Or Button Reset fire alarm system after condition is cleared. Should return to normal condition after resetting. Often required to clear supervisory conditions, does not clear trouble conditions. Smoke detectors must be Cleaned once every 6 months. Test for smoke entry every once a year Primary Power shall be generated electric power not exceeding 277/480 volts Secondary Power Source Batteries shall not be a sub for connection to the secondary source Manual Pull Station~Manually pulling handle Return handle to normal position. A key or other method may be required to reset the station to normal Smoke, beam, and duct detectors~ Detection of particles of combustion Smoke detectors will normally reset when the reset button is pressed at the FACP if the condition activating the detector has been cleared Heat detectors~ Abnormally high temperature After activation most Fixed temperature heat detectors will not self restore and will require replacement by a qualified service technician. Rate of rise detectors will normally self- restore after activation. Water-Flow device~ Flow of water in a sprinkler system Device should return to normal when water ceases to flow. Smoke Detectors Smoke Detectors is a device that detects visible and invisible particles of combustion. Smoke detectors detect most fires much more rapidly than heat detectors. Smoke detectors are subject to mechanical damage they shall be protected.
