TST INPUT LOGIC
The dual color LED may be enabled remotely for walk testing with a
test switch connected to the TST input as shown in Figure 6:

3.4 The Power-up Process
After connecting the (+) and (–) terminals to the power source, the
DUET-AM C/O starts a 60-second warm-up period, indicated by
alternate flashing of the green and red lights.

Caution! If the alternate flashing of the red and green lights does not
stop within 60 seconds, a failure has been detected by the self-test
circuitry or, if mode switch 3 is set to ON, the unit may be masked
(refer to Para. 3.5).

3.5 What Happens in Case of Masking?
Attention! The following procedure is true only while mode switch 3
is in the ON position.

If an attempt is made to stick masking material over the lens or put
a masking object close to the lens, a trouble alert will result about 60
seconds after masking:

3.6 Visual Indications
The dual color LED is used to signal various alarm and trouble
messages as shown in Table 1 below:

Notes:
1. During walk testing, the green light glows steadily (MW detection)
or flashes (PIR detection), depending on which one of the two
sensors discovered the movement first. Upon subsequent
discovery of the movement by the other sensor, the green light
goes off and the red light glows (alarm).

3.7 Mode Selector
The DIP switch mode selector is mounted on the unit’s PC board
(see Figure 4). It controls four functions as demonstrated in
Figure 7.

3.8 Vertical Adjustment
The vertical adjustment scale for the PIR sensor is located at the
upper right edge of the PC board (refer to Figure 4). Three positions
are available - FAR, MID and NEAR. All new DUET-AM C/O units are
set to the FAR position.
Note: For the optional long range lens No. 34D, the vertical
scale should be in FAR position.
To adjust, loosen the vertical adjustment screw, slide the PC board
along the vertical slot until the pointer indicates the required position
on the scale (see Figure 8). When done, tighten the adjustment
screw firmly.

3.9 Setting the Motion Event Counter
If you wish to set the PIR sensor for maximum false alarm immunity, shift
DIP switch No. 1 (SW-1) to ON. In this position, two consecutive motion
events are required to trip the PIR sensor. For faster catch performance,
shift SW-1 to OFF. In this position, only one motion event is required to trip
the PIR sensor.
