1 A GUIDE SECURITY SYSTEM DESIGN QUESTIONS 1. systems have a local alarm that has a 5-minute delay device built in. (a) Proprietary (c) Local (b) Extent of Alarm (d) Police station-connected 2. The primary power supply for the alarm system is the supply to the building. (a) electricity (c) transformer (b) battery (d) rate of reduction 3. is known as the simultaneous transmission of multiple signals over a single transmission system. (a) Singleplexing (c) Multiplexing (b) Statmux (d) Generalplexing 4. When appropriate functional tests of security system parts are completed, arm the movement detector in the system, but connect it to a fault analyzer for a period. If, after this period, no faults are found in the system's operation, the detectors may be connected to the control panel. (a) 3-day (c) 10-day (b) 7-day (d) 30-day 5. With the device, the moving object is seen as a frequency change. (a) doppler shift (c) standing wave (b) transducer (d) signal processor 6. The two major types of interference of alarm systems are. (a) TMI and FFI (c) RFI and TMI (b) RFI and EMI (d) EMI and FFI 7. The speed in which the guard arrives at your premises is known as. (a) Grade of Community Station guard response (b) Grade of Central Station guard response (c) Grade of Public Station guard response (d) Grade of Neighbor Station guard response 1 Exam Prep A Guide to Security System Design 1

2 8. The primary power supply for the alarm system is the supply to the building. (a) electricity (c) transformer (b) battery (d) rate of reduction 9. The largest single destroyer of system components of instigator of false alarms caused by other than human incompetence is. (a) lightning (c) water (b) thunder (d) moisture 10. The determines the bandwidth of data transmission frequencies the cable will carry and the attenuation loss limit within the cable. (a) width of fiber (c) cable composition (b) optical fiber (d) grade of fiber 11. The line connects the satellite to the central station that might be 50 miles away. (a) station (c) telephone (b) trunk (d) security 12. The is more substantial and is designed specifically for commercial applications, as opposed to domestic use. (a) pressure mat (c) pressure pad (b) piezo mat (d) piezo pad 13. Radio sources transmitters, CB radios, police radio transmitters, and discharge lighting cause. (a) EMI (c) RFI (b) FFI (d) none of the above 14. Only type batteries should be used on security systems. (a) open or wet (c) open or sealed (b) sealed or gelcell nongasing (d) gelcell or wet 15. It is essential that the be screened from the effects of radiated RFI and EMI. (a) control panel and wiring (c) wiring (b) control panel (d) ground or wiring 1 Exam Prep A Guide to Security System Design 2

3 16. In a system, a single transmission of cable links various buildings within a neighborhood under different or the same ownership. (a) direct current transmission (b) signal transmission medium (c) McColloh loop (d) alternating current transmission. 17. If the frequency of the alternating current in the circuit is gradually raised, the current flowing through the inductor will decrease and the current flowing through the capacitor will increase. This is referred to as the frequency. (a) analyzer circuit (c) resonant (b) proximity (d) positive 18. If a sound transmitter is placed on one side of a room and a receive on the other, and the transmitted sound is given a frequency of 4000 Hz, the receiver will receive a sound with frequency the same 4000 Hz, because S is constant and X is constant. (a) doppler shift (c) standing wave (b) transducer (d) signal processor 19. Class level security lighting provides acceptable protection of high or moderate values against a deliberate criminal with moderate level of skill. (a) D Basic (c) B Advanced (b) C Intermediate (d) A Maximum 20. Camera are usually expressed in inches generally the larger the diameter, the better the resolution and the lower the limit of usable light. (a) tubes (c) diodes (b) formats (d) coupling devices 21. Basic equipment types defined by their zonal pattern of sensitivity areas or facets are. (a) long-range, dual zone, narrow coverage; and long-range, multizone, narrow coverage (b) multizone, barrier coverage; and broad spread, multizone, volumetric (c) ceiling-mounted, 360 coverage, two-zone (d) all of the above 22. Areas of increased infrared energy (IRE) will in temperature. (a) rise (c) remain constant (b) fall (d) vary 1 Exam Prep A Guide to Security System Design 3

A device that acts on the principal of ground-wall, or fence-born vibration to induce a current is known as a. (a) analyzer (c) buried line (b) piezoelectric (d) geophones 25. A is used to test the efficiency of fiber, which determines the loss in decibels of the light signal and the length of the cable. (a) Voltage Ohm meter (VOM) (b) Time Domain Reflectometer (TDR) (c) Optical Time-Domain Reflectometer (ODTR) (d) Optical Source Reflectometer (OSR) 26. systems transmit VHF as a burst of encrypted pulses of energy toward the receiver cable. (a) pulsed wave (c) carrier wave (b) amplitude (d) phase wave 27. systems have a local alarm that has a 5-minute delay device built in. (a) Proprietary (c) Local (b) Extent of Alarm (d) Police station-connected 28. is known as the simultaneous transmission of multiple signals over a single transmission system. (a) Singleplexing (c) Multiplexing (b) Statmux (d) Generalplexing 29. is the most common rechargeable cell found in security systems.
