82

Specifications

 

1.1 DESCRIPTION:

  1. This section of the specifications includes the furnishing, installation, and connection of the microprocessor controlled, addressable reporting fire alarm equipment required to form a complete coordinated system ready for operation. It shall include, but not be limited to, alarm initiating devices, alarm notification appliances, fire alarm control panel, auxiliary control devices, annunciators, and wiring as shown on the drawings and specified herein.
  2. The fire alarm system shall comply with requirements of NFPA standard No. 72 for protected premises signaling systems except as modified and supplemented by this specification. The system shall be electrically supervised and monitor the integrity of all conductors.

1.2 SCOPE:

  1. A new addressable reporting, microprocessor controlled fire detection system shall be installed in accordance with the specifications and drawings.
  2. Basic Performance:
  3. Alarm, trouble and supervisory signals from all intelligent addressable reporting devices shall be encoded onto a Class B (NFPA Style 4), or Class A (NFPA Style 6, 7) Signaling Line Circuit (SLC).
  4. Initiation Device Circuits (IDCs) shall be wired Class B (NFPA Style B) or Class A (NFPA Style D).
  5. Notification Appliance Circuits shall be wired Class B (NFPA Style Y) or Class A (NFPA Style Z).
  6. Built-in Horn Strobe Synchronization w/ selective silence.
  7. Digitized electronic signals shall employ check digits or multiple polling.
  8. A single ground or open on the system Signaling Line Circuit (SLC) shall not cause system malfunction, loss of operating power or the ability to report an alarm.
  9. Alarm signals arriving at the main FACP shall not be lost following a power failure (or outage) until the alarm signal is processed and recorded.
  10. Basic System Functional Operation

When a fire alarm condition is detected and reported by one of the system initiating devices the following functions shall immediately occur:

  1. The System Alarm LED shall flash.
  2. A local piezo electric signal in the control panel shall sound.
  3. A 80-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 the information associated with each new Fire Alarm Control Panel condition, along with time and date of occurrence.
  5. All system output programs assigned via control-by-event equations to be activated by the particular point in alarm shall be executed, and the associated System Outputs (alarm Notification Appliances and/or Relays) shall be activated.
