Every area of the building shall be patrolled at least once every hour. They must maintain records of their patrols. Where should the emergency preparedness plan be?

Call CS and take the fire alarm system off-line 2. Upon confirmation, a system off-line entry should be made in the log book. What four things need to be documented on the off-line entry during drills? 1. Time system was taken off-line 2. Reason the system was taken off-line 3. Central Station name and telephone number 4. Time the system was restored Who participates in drills? All building occupants, including shelter residents and employees. Who is authorized to report a fire or explosion to the fire department? Any owner, occupant or other person who becomes aware of a fire or explosion or any other emergency should immediately report the emergency to the fire department. The Coordinator of Fire Safety & Alarm Systems in Homeless Shelters must always be knowledgeable about the location on the premises of the following four things: 1. Emergency Preparedness Plan for the shelter 2. Floor plans 3. Firemen's Service Elevator Keys for the elevator car doors must be kept at the fire commant station for immediate use by the department. 4. List of building occupants who require assistance during an evacuation. What are some ways an alarm might alert occupants? Loud sirens, bells, speakers, horns, and flashing lights (strobes). Who is responsible for ensuring the inspection, testing, and maintenance for alarms are scheduled? Coordinator of Fire Safety & Alarm Systems Fire Alarm Control Panel (FACP) Monitors inputs and controls output through various types of circuits. What are the three types of signals from the control panel and what do they mean? 1. Alarm Signal: A signal initiated by a fire alarm initiating device such as a manual fire alarm pull station, automatic fire detector, water flow switch, or other devices in which activation indicated the presence of a fire. Sends a signal to an FDNY 2. Supervisory Signal: Indicates that a system or device being monitored has been compromised or is in an abnormal state. This needs to be investigated and corrected. 3. Trouble Signal: A signal initiated by the fire alarm system ore device that indicates a fault in a monitored circuit or component. This needs to be investigated and corrected. For example, low battery, AC failure, phone line failure, or internal component failure. (Electrical issue in the system) Alarm Silence Switch or Button Silence switch is used to silence the devices after evacuation is complete while investigation is being done. When should you reset the fire alarm system? Never reset the fire alarm system until the condition is verified by FDNY personnel. Primary Power Supply The main power supply for a fire alarm system Secondary Power Supply The fire alarm system shall have a secondary power supply which provides power to the alarm system within 10 seconds of failure of the primary supply. Automatic Detection Devices Sensors that detect heat, smoke or the flow of water in a fire alarm system. Area Smoke Detector Detects visible or invisible particles of combustion. Elevator Lobby Smoke Detectors Smoke detectors that when activated will recall elevators automatically to the designated landing. Beam Detectors Used to protect large areas. This detector consists of a light beam that when broken by anyt combustible particle will trigger the detector Duct Smoke Detectors Sample air flow in the HVAC air duct and to detect particles of combustion. Heat Detector A sensor that detects abnormall high temperatures or rate of temperature rise. What are the two types of heat detectors and what are they? 1. The rate-of-rise heat detectors: Activate the alarm when the room temperature increases at a rapid rate. This type of detector is more sensitive than the fixed temperature detector. The rate-of-rise heat detector does not have to be replaced after it has been activated. 2. Fixed-Temperature Heat Detectors: Trigger the alarm when the detector components melt at a preset temperature level. Normally require replacement after they have activated an alarm. Single Action Pull Stations Requires only one step to activate the alarm Double Action Pull Station Require two steps in order to activate the alarm Supervisory Devices Monitor important parts of the system What are the four common supervised conditions for a supervisory alarm? 1. Control Valves on sprinkler sstems to ensure they remain open 2. Pressure supervisory switch controls the pressure level in pressure tanks 3. Gravity tanks are supervised for high or low water level and high or low temperatures 4. Electric fire pumps are supervised for pump running, pump failure, and phase reversal What are the two methods used to notify building occupants and employees of a fire emergency at the fire alarm panel? 1. General Alarm Method: This method activates all audio/visual devises throughout the bu8ilding when a fire is detected. 2. Selective Alarm Method: The selective method activates the audio/visual devises only on the floor of alarm as well as the floor immediately above and below. Central Station Transmitter A device that receives alarm signals from protected premises and retransmits those signals to the Fire Department's Bureau of Fire Communication Automatic Sprinkler System Wet system, filled with water Non-automatic Sprinkler System Dry system, no water Standpipe System Provides water that firefighters can manually discharge through hoses onto a fire. Standpipe systems are required in buildings that are over 75 feed in height. HVAC System The supply and movement of air is a primary determinant of the severity of a fire event in a building. It is important that air movement be shut down during a fire. HVAC systems are interfaced to fire alarms so that an alarm signal from the fire alarm witll cause the air handling systems in the area of th alarm to shut down. Smoke Dampers Open and close when required to provide fresh air or to stop smoke passage. Fire Dampers Close when a rise in temperature occurs Fire Watch a fire watch shall be maintained by one or more persons holding a certificate of fitness as fire guard. Fire guards must be immediately available when the system is out of service except for when the affected area does not exceed 50,000 square feet Portable Fire Extinguishers Portable fire extinguishers weighing 40 lbs or less must be installed so that the top of the extinguisher is not more than 5dr above the floor.
