    2.11 OPERATION OF FIRE ALARM SYSTEM

    A. Activation of the fire alarm system shall directly initiate some or all of the followingto be agreed as a part of the overall engineering policy.

    1. Signal to all elevator machine rooms indicating fire status (to control lifts)2. Release doors normally locked by magnetic devices.3. Release doors normally held open by magnetic devices4. Shutdown mechanical equipment ventilation plant5. Shutdown general exhaust fans6. Start up smoke extract fans7. Start up exhaust make up fans8. Start up stair vestibule pressurization fans9. Automatically operate fire dampers10. Initiate alert signals to panels in the adjacent office tower.11. Sprinkler valves, flow switches and other monitored valves shall be directly

    supervised by the fire alarm systems.

    B. Fire condition:

    When a fire alarm condition is detected and reported by one of the systeminitiating devices or appliances, the following functions shall immediately occur:

    1. The system alarm LED shall flash.2. A local piezo-electric audible device in the control panel shall sound a

    distinctive signal.3. The 640-character backlit LCD display shall indicate all information

    associated with the fire alarm condition, including the type of alarm point

    and its location within the protected premises.4. Printing and history storage equipment shall log and print the event

    information along with a time and date stamp.5. All system outputs assigned via preprogrammed equations for a particular

    point in alarm shall be executed, and the associated system outputs (alarmnotification appliances and/or relays) shall be activated.

    Activation of the control panel acknowledge switch in response to newalarms and/or troubles shall silence the local panel piezo electric signaland change the alarm and trouble LEDs from flashing mode to steady-ONmode. If multiple alarm or trouble conditions exist, depression of thisswitch shall advance the LCD display to the next alarm or trouble

    condition. In addition, the FACP shall support Block Acknowledge to allowmultiple trouble conditions to be acknowledged with a single depression ofthis switch. Depression of the Acknowledge switch shall also silence allremote annunciator piezo sounders

    Depression of the Signal Silence switch shall cause all programmed alarmnotification appliances and relays to return to the normal condition. Theselection of notification circuits and relays that are silence able by thisswitch shall be fully field programmable within the confines of all applicablestandards. The FACP software shall include silence inhibit and auto-silence timers.
