SENSITIVITY ADJUSTMENTS
1.
Adjust the EVD-M’s internal pickup sensitivity control, RV1, to 1/2 scale (12 o’clock
position). Refer to Figure 1 for adjustment location.
2.
If remote pickups are installed, adjust the EVD-M’s remote pickup network
sensitivity control, RV2, to the minimum setting listed in Table 2. If no EVD-R’s are
installed, adjust RV2 to the minimum setting, fully counter-clockwise. Refer to
Figure 1 for adjustment location.

Adjust accumulator rotary switch, S1, to desired setting. A setting of zero disables
the accumulator function. Refer to Figure 1 for adjustment location.
4.
Perform simulated attack tests on all accessible surfaces that are protected by the
EVD-M and EVD-R’s. Strike the protected surfaces using a plastic mallet or the
plastic handle of a large screwdriver. An alarm condition (as indicated by the
status LED turning RED) must occur. Lightly scrape the blade of a screwdriver
next to the EVD-M and each EVD-R. After 15 seconds of continuous scraping,
an alarm condition (as indicated by the status LED turning RED) must occur. Be
sure the scraping generates a test point voltage greater than the
minimum constant noise level shown in Table 3. Adjust sensitivity settings
to the minimum needed to achieve desired level of response.
NOTE: Extreme care should be exercised so that the protected surfaces
are not marred or damaged while performing simulated attack tests.
A voltmeter can be connected to the analog test point and pin 2 of the field wiring
terminal block to aid the installer in adjusting the sensitivity controls. Refer to
Figure 1 for analog test point location.

With the system operating in a non-alarm state, verify the operation of all tampers.
A tamper condition is indicated by the status LED turning AMBER. If the system
is in alarm when a tamper condition occurs, the status LED will remain
RED, identifying the alarm condition. The tamper alarm remote annuncia-
tor and the tamper alarm contact always identify a tamper condition.
