Input power
6 VDC to 15 VDC; 18 mA at 12 VDC
Operating
temperature
The storage and operating range is
-40°F to +120°F (-40°C to +49°C).
For UL Certi

Alarm relay
Form “C” reed relay with contacts rated
at 28 VDC, 125 mA maximum for DC
resistive loads.
Tamper

Standby power
No internal standby battery. Unit is
intended to be connected to DC power
sources capable of supplying standby
power in the event primary power
fails. 18 mAh are required for each
hour of standby time needed. For UL
Certi
fi
cated Installations, a minimum of
4 hours (72 mAh) is required.
10 | Coverage patterns
9 | Masking
1. Replace the cover.
2. Apply power to the unit.
3. Wait at least two minutes to start the walk test.
4. Walk test across the coverage pattern. Refer to
Figure
6.1
.
5. Determine the edge of the coverage by activating the
alarm LED. This changes depending upon the sensitivity
switch settings.
6. Walk test the unit from both directions to determine the
boundaries.
7. If you cannot achieve the desired range, try angling the
mirror up or down to assure the coverage pattern is not
aimed too high or low.
6 | Walk test
Figure 6.1 Walk test pattern
1. Connect a DC VOM to the Noise Voltage pins (use TC6000).
2. Replace the cover, routing the TC6000 cable through the
notch in the top of the case.
3. Set meter scale for about 3.0 VDC.
4. The base reference level for reading background noise is
approximately 2.0 VDC.

NOTICE!
Meter readings are very important in determining
background disturbance levels and catch margin
sensitivity.
Figure 7.1 Meter reading
Use an ohm/volt meter to measure the background noise
voltage.
8 | Maintenance
At least once a year, check the range and coverage in
accordance with
Section 5
.
Instruct the end user to walk through the outer edge of the
coverage pattern. This ensures an alarm output prior to
arming the system.
Before attempting any masking, be sure the mirror surface
is the correct one. Use
Figure 10.1
to determine the
relationship between mirror sections and the pattern.
Attempting to remove masking might destroy the mirror
surface or leave enough residue behind to reduce coverage
performance. Refer to
Figures 9.1 and 10.1.

5. Installations in quiet environments result in a steady reading
between 1.9 VDC and 2.1 VDC.
6. Voltage changes greater than 0.75 VDC from the reference
level are desirable for good catch performance.
7. If changes are less than +0.75 VDC, the device might fail to
respond if the temperature between the intruder and the
background is minimal.
8. Turn on all heating and cooling sources that are normally in
operation during times of protection.
9. Stand away from the unit and outside the coverage pattern,
then monitor the background noise for at least 3 minutes.
10. Readings should not deviate from the reference level by
more than ±0.15 VDC.
11. For readings outside these limits; eliminate the cause, re-
aim the unit slightly, or mask off the affected zones.
