The sensitivity of security levels from 0 to9 should be further adjustable in steps. The sensitivity step 0 represents the highest sensitivity of that level and sensitivity decreases with the increase in the sensitivity steps. 4. The sensitivity level of security level 0 / NC should be fixed. d) Alarm Volume Adjustment: 1. The control unit display panel should have option of selecting from eleven separate alarm volume.

5 2. The 0 level should disable the alarm tone. 3. Level 1 should be lowest alarm tone. 4. Level 10 should be loudest alarm tone. e) While in operation the LCD should always display the IN and OUT counters separately, along with the Security Level. f) Automatic Display of Failure code on LCD: The MZDFMD fails to program/detect/auto tune/etc., the LCD should display the failure code. The details of failure code should be mentioned in the operational & installation menu and should be supplied along with every unit. g) The control unit display panel should have option of setting the MZDFMD at factory default settings. The details of factory settings of various features should also be mentioned in the operational & installation menu. 10. Detection: a) Capable to detect all Metals, Zinc & Metal Alloy, using single detection programme. Should be able to detect ferrous/non-ferrous metals at any location as per relevant IS Spec. b) Continuous active detection capability-quick reset after each detection. Should allow up to 30 person per minute to pass through MZDFMD.
