PART 1 - GENERAL

1.1

SUMMARY

A.

This section covers all general paging system as shown on the drawings or as required to support the systems defined in these specifications. The work under this section consists of furnishing materials and equipment, performing labor and services necessary for the installation of the general paging system required for the security electronics, communications, and fire alarm system.

B.

Related Work Specified Elsewhere: Refer to all other Division 17 specification sections and drawings, and to the specifications and drawings under the General Construction

Contract to ascertain the extent of work included.

1.2

SUBMITTALS

A.

Since the Division 17 systems must be reviewed by the Contracting Officer as a system, no individual, specific submittal shall be made for this section. Submittals shall be packaged in groups and shall be made in accordance with the General Provisions (Section 17000) of these specifications.
