Supervising station located at the protected premises

This preview shows page 1 - 3 out of 4 pages.

supervising station located at the protected premises, or at one of multiple noncontiguous protected premises, at which trained, competent personnel are in constant attendance. This includes the protected premises fire alarm system(s); proprietary supervising station; power supplies; signal-initiating devices; initiating device circuits; signal notification appliances; equipment for the automatic, permanent visual recording of signals; and equipment for initiating the operation of emergency building control services. (SIG-SSS) 72 (2013) Remote Supervising Station Fire Alarm System- A protected premises fire alarm system (exclusive of any connected to a public emergency reporting system) in which alarm, supervisory, or trouble signals are transmitted automatically to, recorded in, and supervised from a remote supervising station that has competent and experienced servers and operators who, upon receipt of a signal, take such action as required by this Code. (SIG-SSS) 72 (2013)
Initiating Devices- A system component that originates transmission of a change of-state condition, such as in a smoke detector, manual fire alarm box, or supervisory switch. (SIG-IDS) 72 (2013), 909 (2013), 914 (2010), 731 (2011) Notification Devices- A fire alarm system component such as a bell, horn, speaker, light, or text display that provides audible, tactile, or visible outputs, or any combination thereof. (SIG-NAS) 1. Discuss the differences/similarities between Ionization smoke alarms and Photoelectric smoke alarms? Use illustrations to assist with the discussion. (4 pts) Ionization smoke alarms are generally more responsive to flaming fires. How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm. Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”). How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor. Smoke enters the chamber, reflecting light onto the light sensor; triggering the alarm. For each type of smoke alarm, the advantage it provides may be critical to life safety in some
