r. Sensor Devices (Interior) (See Figure 1-22.)

(1) Balanced Magnetic Switch (BMS) (standard and low profile). The Balanced Magnetic Switch (BMS) detects

the opening of doors, including roll up doors, and windows. The Balanced Magnetic Switch (BMS) will alarm when

the separation between the magnet and switch assembly changes by 0.80 0.40 inches on any plane or when the

local magnetic field has a positive or negative difference from the initial adjustment.

(2) Passive Ultrasonic Sensor (PUS). The Passive Ultrasonic Sensor (PUS) detects ultrasonic energy generated

by drills and other intrusion tools during attempts to penetrate through the perimeter (walls, doors, window, ceilings)

of the protected area.

(3) Vibration Sensor (VS). The Vibration Sensor (VS) detects vibrations generated during attempts to penetrate

through the perimeter of the protected area.

(4) Microwave Motion Sensor (MMS). The Microwave Motion Sensor (MMS) detects intruder motion within a

protected area. It has a single antenna Doppler sensor operating at microwave frequencies.

(5) Ultrasonic Motion Sensor (UMS). The Ultrasonic Motion Sensor (UMS) detects intruder motion within a

protected area. The sensor detects Doppler shifts in the ultrasonic signal generated by intruder motion.

(6) Capacitance Proximity Sensor (CPS). The Capacitance Proximity Sensor (CPS) can be used either as a

penetration sensor or as a point sensor. The Capacitance Proximity Sensor (CPS) detects the change in capacitance

between the connected object and ground resulting from the close approach or touch of an intruder. The

Capacitance Proximity Sensor (CPS) has a field adjustable sensitivity control. The Capacitance Proximity Sensor

(CPS) adjusts to slowly changing values of total capacitance caused by the environment without alarm.

(a) As a penetration sensor it is connected to isolated metal bars, mesh, or screens which cover windows, vents,

and other openings.

(b) As a point sensor it is connected to safes, file cabinets, and other metal objects.

(7) Passive Infrared Motion Sensor (PIMS). The Passive Infrared Motion Sensor (PIMS) detects intruder motion.

It is available in three configurations. All configurations alarm at 2 degree celsius temperature differential between

the intruder and the background.

(a) Volumetric. The detection pattern extends from 8 feet to 30 feet and at angles up to 60 degrees.

(b) Curtain. The detection pattern extends from the sensor mounting level to the floor, to a minimum of 30 feet,

and at angles up to 3 degrees. The maximum angle covered by the sensor is approximately 6 degrees.

(c) Omni-directional. The detection pattern extends out to 30 feet from a point directly beneath the sensor and

all angles about a line through this point.

1-15. DIFFERENCES BETWEEN MODELS. There are two different configurations of the Integrated Commercial

Intrusion Detection System: the Large Primary Monitor Console (LPMC), and the Small Primary Monitor Console

(SPMC). The difference between the two configurations is the quantities of equipment. The LPMC can monitor up to

256 zones. The SPMC can monitor up to 64 zones. Table 1-1 provides the differences between the Large and Small

Primary Monitor Consoles.
