8.0 Final Tests
10.0 Coverage Patterns
NOTE: Meter readings are very important in determining back ground disturbance levels and catch margin sensitivity.
•Connect a 20,000 ohm/volt (or greater) DC VOM to the Noise Voltage connector pins as shown. Set meter scale for about 3 VDC. Route meter wiring through the slot in the base. (Use of the TC6000 is recommended, but is not essential for meter use.)
•The base reference level for reading background noise or target voltages is approximately 2.0 VDC. Installations in quiet environments, therefore, will result in a steady meter reading between 1.9 and 2.1 VDC.
Voltage changes greater than 0.75 VDC from the reference level are desirable for good catch performance. If changes are less than ±0.75 VDC, the device may fail to respond at this distance if the temperature difference between the intruder and the background is very small.
•Turn on all heating and cooling sources that would normally be in operation during times of protection. Stand away from the unit and outside the coverage pattern, then monitor the background noise for at least three minutes.
DS794Z readings should not deviate from the reference level more than ±0.15 VDC. For readings outside these limits; eliminate the cause,

9.2 Sealing the Wire Entrance
•The foam plug that is provided with the unit is for sealing the wire entrance from drafts and insects.
9.3 Maintenance
•At least once a year, the range and coverage should be checked according to Sections 7.0 and 8.0 (Walk Testing and Final Tests).

•To ensure continued daily operation, the end user should be instructed to daily walk through the far end of the coverage pattern. This assures an alarm output prior to arming the system.
9.4 Mirror Module Information
•Should the mirror surfaces become soiled or dirty, clean using a soft clean cloth and any commonly available mild window cleaner.
9.5 Masking
•Refer to the mirror module and pattern drawings for masking information.

•Before attempting any masking, be sure the chosen mirror surface is the correct one. When attempting to remove any masking, many adhesives will either destroy the mirror’s surface or leave enough residue behind to reduce coverage performance.
•Shaded areas of the mirror drawings do not affect the pattern and, therefore, are not maskable.
