(2) Card reader. The use of access readers provides two optional features for the ICIDS system, called
Accountability and Messaging. Accountability enables the current location of all authorized personnel to be recorded
by monitoring their access into and out of each protected area. System operators can create displays which list the
personnel within each protected area and may also review the movements of an employee on a particular day or
during a selected time.
(3) Intelligent Access Unit (IAU). The IAU is a combination keypad and card reader.
(4) Starlink Keypad. The Starlink Keypads operate as Access/Secure initiating devices for their alarm zones. The
keypad can also be used to review the status of the sensors in the zone, extend the normal working hours of the
zone, and initiate duress codes and sensor tests.
Before operating the keypad, PIC numbers must be assigned to the zone. To use the keypad, the user enters the PIC
number on the keypad. The date and time will disappear and "PIC #" followed by an asterisk (a) in place of each digit
of the PIC number will appear.
Six digits must be entered for the PIC number. If more digits are entered, the readout will return to the Log Screen. If
fewer than six digits are entered, the keypad will return to the login screen. The keypad will allow three attempts to
enter the correct PIC number. Then if the number is not entered correctly, the screen will return to the login screen.
I. Sensors. The ICIDS provides a set of interior and exterior sensors for different applications. Each ICIDS site will use a
combination of different sensors that will best protect the site according to its individual environment and operational
characteristics.
interior sensors detect the presence, movement, sound, or other activities of an intruder. They are for indoor use only.
They are categorized into three functional groups: boundary penetration, volumetric motion, and point. Boundary
penetration sensors are used on ceilings, roofs, windows, walls, floors, and doors. Volumetric motions sensors detect
physical motion within an area. Point sensors protect smaller areas within a larger area, or specific items within an area.
Exterior sensors detect an intruder crossing the boundary of an area being protected. They can be used for protection of
materials and equipment stored outdoors within a protected boundary, or for perimeter detection for buildings and other
facilities. The exterior sensors perform with a minimum of false alarms caused by wind, rain, ice, standing water, blowing
debris, animals, or other environmental sources.
The ICIDS includes a variety of sensors, both interior and exterior, for use in the remote areas. Sensor groupings are as
follows:
(1) Interior Penetration Sensors.
(a) Balanced Magnetic Switch (BMS). The BMS contains a magnetic reed that is balanced between an internal bias
magnet and an external actuating magnet. When a door or window is opened, the movement of the actuating
magnet's field unbalances the switch and causes an alarm. If a bypass is attempted by placing another magnet near
the switch, this third field will also unbalance the switch and cause an alarm.
(b) Vibration Sensor (VS). The VS detects vibrations produced by drilling, hammering, cutting, explosions, and
other methods of forcible entry. Since a single vibration may not indicate intrusion, the VS will alarm only when
several vibrations, or one of explosive magnitude, are detected.
