(dependent on the sensitivity setting) in one direction shall cause an alarm; however, <br />incidental vibration or fluctuating movement of trees, bushes, swinging signs, etc. shall <br />be rejected by the sensor's circuitry. The 10- position digital Sensitivity Control Switch <br />shall adjust the microwave sensor detection sensitivity in 4" (10 cm) increments. <br />C. Passive Infrared Sensor: The passive infrared sensor portion shall use a- dual element <br />pyro- electric detector. The dual elements shall sense infrared energy, and the voltage <br />output of the dual elements shall be of opposite polarity and combined into a single <br />output. An intruder crossing the sensor field of view will be detected by causing a large <br />voltage swing, first in one polarity and then in the other. However, large area changes <br />in background infrared radiation shall result in a signal of minimum voltage amplitude <br />(and no detection), with the opposite outputs for the dual element detector canceling <br />each other. The Sensitivity Control Switch shall adjust the passive infrared detection <br />sensitivity. <br />D. Sensor's relay shall change state in response to intrusion, tamper, and component <br />failure alarms. <br />E. System Criteria <br />1. Detection range shall be adjustable. <br />- - 2. Detection sensitivity shall be adjustable, enabling the selection of distance an <br />intruder is required to move in one direction before causing an alarm. <br />3. Sensor shall have the ability to ignore flying birds. <br />4. Sensor shall have the ability to adjust immunity to birds and small animals. <br />5. Sensor shall have an adaptive signal processing for extreme environmental <br />conditions. <br />6. Circuit supervision shall cause a lock -in alarm condition with failure of a major <br />component. System shall not function as a single technology unit. <br />7. Multiple sensors shall be compatible in the same area without mutual interference. <br />8. Sensor shall be equipped with Walk -Test and Environmental Caution Indicator lights <br />with internal disable switch. <br />9. Sensor shall be equipped with externally accessible receptacle for plugging -in a <br />sounder during set -up and walk -test. <br />10. Sensor shall be equipped with Form C Relay with terminal connections. <br />11. Sensor shall be equipped with housing tamper with terminal connections. <br />12. Housing shall be metal, heavy -duty, and vandal resistant. Housing shall be <br />equipped with weather shroud to keep rain and melting snow away from the sensor <br />face. Weather shroud shall also minimize direct sunlight on the IR lens. <br />13. Mounting shall be swivel type with 180 degree horizontal and 90 degree vertical <br />adjustment. <br />F. Motion Detectors shall be powered by 12VDC nominal, temperature rating of —30 to 130 <br />deg F, microwave frequency range of 10,525 MHz. The Motion - Detector shall provide -a <br />form C Relay closed in normal position for tamper protection. The alarm output shall <br />change state when an intruder moves within the protection pattern. The Motion <br />Detectors with a 50'x50' detection pattern shall be ProTech Piramid No. SDI -76XL2 or <br />approved equal. The Motion Detectors with a 90'x50' detection pattern shall be <br />ProTech Piramid No. SDI -77XL2 or approved equal. See Table 2.2 for required <br />motion detectors. <br />City of Santa Ana Security Management System Specific Requirements <br />Security Management System Project Page 17100 -5 <br />SantaAna_SMS_17100 <br />
