12.9.2 Intrustion Detection Systems
12.9.2.1 Joint Services Interior Intrusion Detection Systems (J-SIIDS) (Revised September 2002)
For the past 20 years, J-SIIDS has been the primary government-owned intrusion detection system.
All the arms storage facilities on Fort Carson had been equipped with the J-SIIDS until August of 1995. At that time, a full conversion to an Integrated Commercial Intrusion Detection System (ICIDS) occurred.
Installed J-SIIDS were retrofitted to facilitate interfacing with the ICIDS monitoring equipment.
12.9.2.2 Integrated Commercial Intrusion Detection Systems (ICIDS) (Revised September 2002)
12.9.2.2.1 Description
The ICIDS is an integrated system which includes interior and exterior sensors, closed circuit television (CCTV), entry control equipment (ECE), communications links, and alarm reporting systems for monitoring control and display of various alarm and monitoring information. The ICIDS consists of a family of commercially available, reliable, state-of-the-art, standardized, intrusion detection equipment that is being installed at Department of Defense (DoD) facilities worldwide to enhance the physical security of the site and sensitive assets. It will be used by security and law enforcement agencies to provide a standard intrusion detection capability. The ICIDS is a Non-Developmental Item (NDI) Basic Acquisition Program, composed of commercially available components.
Functional aspects of the ICIDS equipment are described in the following:
12.9.2.2.2 Primary Monitor Console (PMC)
The PMC has software used to control the system. The program is invoked when the system is initialized and acquires data from each Remote Area Data Collector (RADC) it is monitoring. If a RADC fails to respond, the system alarms and notifies the operator.
12.9.2.2.3 Operator Workstation
The Operator Workstation allows operators to monitor the status of all equipment with the security system. Commands are entered into the system using the workstation keyboard. A legend of the available soft-keys appears on each operator’s display and changes to reflect alternative soft-key options.
12.9.2.2.4 Remote Area Data Collector (RADC)
A network of RADCs monitors and controls all intruder detection and access control equipment. Each RADC compiles a list of readings and changes, which it transmits to the PMC. The readings are then processed and stored, and operators’ displays are updated to reflect any detected changes.
12.9.2.2.5 Sensors
While the majority of the J-SIIDS sensors were normally connected in a series, with ICIDS they are individually addressed (point sensors) to the control panel RADC. Conduit installed to accommodate IDS sensors should allow for additional wiring from control panel to sensor(s) location.
12.9.2.3 Power Requirements (Revised September 2002)
-
The ICIDS/J-SIIDS is designed to operate on single-phase, 110-V to 125-V, 20amp, 48- to 62-Hz power.
Power should be run from the distribution panel to a 4 square box at the proposed RADC location.
12.9.2.4 Communiation
A conduit raceway needs to be provided from the telephone room to the area to be alarmed with a pull string to separate 4 square box at proposed RADC location.
12.9.2.5 Conduit
The requirements for the use of conduit when installing electronic security systems (ESS) vary from installation to installation. It is incumbent on the designer to research the requirements for a given installation. For instance, the National Electrical Code states that when installing electrical equipment in certain hazardous environments, an explosion-proof conduit system is required. This type of conduit system is quite expensive but is required in order to maintain safety inside the hazardous environment. For many years, conduit systems were required when installing ESS in sensitive compartmented information facilities (SCIFs). However, recent regulatory changes have relaxed these requirements in certain applications. In exterior applications, conduit requirements will be different still and must conform to the requirements of the National Electrical Code. Still, it remains a designer’s responsibility to research and verify conduit system requirements for given ESS installations. The designer must consider factors such as line supervision requirements, safety, potential physical damage, electromagnetic interference. Conduit will be run from proposed RADC location (4 square box) to approved sensor locations (4 square box) with pull strings.
The vast majority of interior ESS installations are neither SCIFs nor hazardous in nature. Therefore, in most areas where ESS is installed, the designer must consider the use of conduit systems in terms of practicality and cost effectiveness. For example, in areas where wiring may be subject to physical damage (from forklifts or other sources), a rigid conduit system may very well be justified. On the other hand, where interconnecting wiring is not exposed (such as above ceilings or concealed inside walls, etc.) and not subject to physical damage, a conduit system may not be required at all. Where wiring will be exposed and subject to only minor physical damage, the designer may choose to use an electrical metallic tubing (EMT) or polyvinyl chloride (PVC) conduit system. While there are no specific regulatory requirements mandating the use of rigid conduit, it remains the responsibility of the designer to determine conduit system requirements for specific ESS applications in accordance with the appropriate and governing regulations, codes, or standards. It is this particular area of concern which leads to the Corps' requirement that firms engaged in this type of design be Registered Professional Engineers proficient in all aspects of the design requirements, codes, and standards in effect at the time of design.
The Corps of Engineers Guide Specifications (CEGS) are a family of generic specifications which must be tailored to specific project requirements. A CEGS by itself does not constitute a requirement until the designer modifies the generic specification to fit a specific project at a specific site. The CEGSs include notes to the designer to assist in making intelligent choices where that latitude exists. The type of conduit system to be provided is one such designer choice. Once modified, the document becomes a project specification. The project specification and design drawings must accurately describe the technical requirements for a specific project, including conduit as well as other regulation, code, or standards driven requirements.
