SECTION 281643 - PERIMETER SECURITY SYSTEMS

In addition to general MasterSpec instructions for coordinating Drawings with Specifications, Drawings should indicate the following information related to this Section:

• Diagrams of system components and interconnections. Use riser diagram format where appropriate. Supplement with block diagrams and subsystem connection diagrams if required.
• Locations and identifications of system devices and equipment, and designations of device types.
• Zone assignments of individual detection devices.
• Coordination of detection patterns of microwave detectors and sensor patterns of adjustable detectors with site plans, site contours, and landscape plans.
• Number of, and dimension or size of, each zone of detection of the video motion sensor system.
• Power to signal processors, actuators, transmitters, and similar site-deployed devices associated with the security system that require 120-V ac to operate. Indicate transfer switch or uninterruptible power supply to the central station where applicable.
• Elevations of control panels and annunciators. Identify central- and local-control panels, and indicate zones of coverage at each monitoring or control station.
• Wiring paths of power, signal, and data to system components on site plans. Coordinate with site utilities and duct bank systems.
• Programmed lighting control override push buttons for security-related lighting zones and control system interfaces on floor and site plans.
• Identification of items to receive tamper switches.
• Where detection devices include separately mounted auxiliary components, locate such components on plans and show wiring connections.
• Precise locations and alignment requirements for photoelectric beam devices. Coordinate with practical equipment limitations as defined by manufacturers.
