CAUTION

The clear protective film and warning label on the smoked
lens of both the receiver and transmitter MUST be removed
before they can operate.

The alignment of the 6424 is divided into three steps: align-
ment setup, alignment of the transmitter, and alignment of
the receiver. It is necessary for all three steps to be executed
properly to ensure proper alignment of the product. If the
6424 is mounted to a recommended surface (see MOUNT-

ING LOCATIONS) and alignment procedures are executed
properly, false alarms and nuisance trouble signals will be
avoided. The alignment procedure is best accomplished by
two individuals. This allows the adjustment of the gain pot
on the receiver during alignment of the transmitter without
the need for several trips back and forth between the trans-
mitter and receiver.

A) ALIGNMENT SETUP:

1) At the transmitter, select the proper range using the

range selection switch (SW2) on the transmitter.

Short Range (S): 30 to 100 feet
Long Range (L): 100 to 330 feet

2) If the transmitter is directly wired to the receiver (Figure

7), slide the alignment switch (SW1) on the transmitter
to the A (align) position (see Figure 15). Point the trans-
mitter directly at the receiver, then go to step 5.

3) If the transmitter is wired directly to a power supply,

it should be temporarily wired to the receiver if pos-
sible (see Figure 8). NOTE: Temporarily wiring the
transmitter to the receiver is beneficial because it acti-
vates the alignment LEDs on the transmitter to allow
alignment of the transmitter without having to look at
the alignment LEDs on the receiver.

4) If the transmitter is not wired directly to the receiver,

make sure the SW1 switch remains in the N (normal)
position (see Figure 15) before going to step 5. Point
the transmitter directly at the receiver.

5) At the receiver, select the proper sensitivity using the

switch on the back of the receiver (see Figure 14).
The sensitivity selected depends on the separation of
the transmitter and receiver. The sensitivities and
ranges shown are in accordance with UL standard
286, Smoke Detectors for Fire Protective Signaling
Systems.

6) Using a small standard screwdriver, make sure the

alignment adjust pot on the receiver (see Figure 17) is
turned fully counterclockwise, looking at it from the
bottom (maximum gain). The alignment adjust pot
changes the gain of the amplifier to compensate for dif-
ferences in separation between the receiver and trans-
mitter and has no effect on the detector sensitivity.
