20、ded by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-10-11 28 31 00 - 4 signal only to a central station that is responsible for dispatching the fire department. The connection to the fire department is usually via a central station monitoring company that is
21、contracted on a monthly basis by the facility. If a connection to the fire department is not already present, the facility will need to determine if there are 2 telephone lines available for this connection. E. The main fire alarm control unit shall automatically transmit alarm signals to a listed c
22、entral station using a digital alarm communicator transmitter in accordance with NFPA 72. 1.2 SCOPE SPEC WRITER NOTE: Scope of Work to include one of the following 3 options for new fire alarm systems. 1.

23、 of an existing non-addressable fire alarm system. 3. A non-addressable fire alarm system as an extension of an existing non-addressable fire alarm system. The following section addresses each scenario. Modify specification accordingly for this project. A. A /fully addressable fire alarm system/ /fu
24、lly addressable fire alarm system as an extension of an existing non-addressable fire alarm system/ /non-addressable fire alarm system as an extension of an existing non-addressable fire alarm system / shall be designed and installed in accordance with the specifications and drawings.
