FIGURE 8 - TESTING THE DETECTORS
TABLE 5 - DETECTOR OUTPUT VOLTAGE LEVELS
4. The voltage levels should meet the “OK” ranges stated
above. If the levels are not “OK,” then locate and remove the
source(s) of ambient noise. Only reduce the sensitivity set-
tings below the recommended levels shown in Tables 1 and
3 after taking all possible steps to eliminate the sources of
noise. If the settings are reduced, ensure, through testing of
all surfaces, that proper detection is maintained.
5. Perform the following tests:
• Scratch the surface around the detector with a screwdriver.
Depending on the strength of the signal you generate, the
detector triggers an alarm within approximately 30 seconds
for the DV1201 and 45 seconds for the DV1221 (the circuit
opens between Terminals 5 and 6). This test simulates an
attack with a drill, diamond disk or a thermal attack.
• Knock firmly with a hammer on the protected surface around
the detector with two-second intervals between blows. After
five blows, the DV1201 alarms. To protect the surface from
damage, place a small aluminum plate between hammer and
surface. This test simulates the attack of a hammer and chis-
el and is only valid for the DV1201.
• Give one powerful blow near the detector with a hammer.
Both the DV1201 and the DV1221 alarm immediately. This
test simulates an attack with explosives.
6. Close the cover of the detector(s) and check for a closed-
loop condition of the tamper loop.
7. Connect the alarm and tamper loop to the alarm panel and
perform a functional test of both alarm and tamper signals
according to panel specifications.
8. Confirm proper activation at the system control to insure
proper loop wiring.
1. Carefully remove approximately six inches of the PVC jack-
et. The outside protective shield detaches with the PVC
jacket, leaving the drain wire loose.
2. To isolate this drain wire from the inside protective shield,
slide a five-inch piece of wire insulator over the exposed
drain wire. Then wrap a layer of electrical tape around the
now-insulated drain wire and the remaining wires at the point
where the PVC jacket is cut. See drawing below.
FIGURE 6 - INITIAL CABLE PREPARATION
3. Remove the mylar wrap isolating the shields and the second
(inside) shield. Cut off both shields at the edge of the
electrical tape.
4. Isolate this drain wire with wire insulator and wrap with a sec-
ond layer of electrical tape.
5. Make connection to the DV1201/DV1221 sensor as indicat-
ed in the Wiring Diagram in Sections 7.0.
FIGURE 7 - FINAL CABLE PREPARATION
5.0 TESTING
1. Prior to applying power, recheck all connections and be sure
all mounting screws are tight.
2. Apply power. Connect an ohmmeter to Terminals 5 and 6 of
the DV1201 or DV1221. Check for a closed alarm loop.
3. Connect a DC volt-meter (internal resistance 20 K Ω or more)
to Terminal 2 (negative) and the test point TP (positive).
Place the volt-meter in the range around 3V. Put the sensi-
tivity selector in the maximum sensitivity position (1). Make
sure that all possible causes for vibrations in the protected
area are present and operating. Check the output voltage
and take measures accordingly. Reduce the detector’s sen-
sitivity until the voltage reading is acceptable or remove the
source of ambient noise.
