DATA ALARMS
3.2 The Installation Procedure
To install your Data Alarm, take these steps:
1. Place the Data Alarm somewhere between the
devices you want to connect, within 6 ft. (1.8 m)
of a working AC outlet.
2. Set the Alarm's DISABLE switch to the DISABLE
(up) position.
3. If you are using 120-volt AC power, go on to Step 4.
If you want 240-VAC output, you will have to set the
Data Alarm's internal power-selection DIP switch.
When the Data Alarm is plugged in, 120 or 240 volts of
AC power passes through its circuitry. NEVER open
the unit or make any internal adjustments to it while it
is plugged into a source of AC power.
First open the Alarm: Unscrew and remove the two
Phillips screws on the bottom of the unit and remove
its cover. You will see a DIP bar switch labeled "S3"
and "120-VAC↔240-VAC" on the Alarm's circuit
board. Move this switch to the "240-VAC" position.
4. If you want the Alarm's output to be switched-ON AC
power (power comes on when data is sensed), go on
to Step 5. If you want switched-OFF AC power (power
goes out when data is sensed) or dry-contact (relay
switches when data is sensed) output, you will have
to rewire the Alarm's terminal block. If you haven't
already, open the Alarm (see the previous step). You
