WIRELESS DA-600 DRIVE-ALERT
PAGE 2 OF 3
Under the unit cover are the address code switches (see FIGURE 1: SW1, SW2, SW3, SW4 in left lower quadrant) that must be
set to match those in the transmitter. These switches are preset at the factory for code 0000. They should only be changed if
the transmitter code is also changed. Also there is an alarm time control (see FIGURE 5 TIME near middle) which is preset at
minimum of 2 seconds of alarm time. The maximum alarm time is 12 seconds. LED 4 (VALID XMSN) is on when the Receiver
detects a valid transmission of its address and LED 3 (ALERT) is on when the relay is closed. On the outside of the Receiver is
a WHISTLE ON-OFF switch. This switch basically provides or removes the 24 volt DC available at the relay output. The
common contact of the relay receives 24 volts DC from this switch. In the “whistle off” position, the relay provides Form C dry
contacts for external device control.
DA-600 CONTROL PANEL TERMINALS
:
The terminal block, TB1, provides a convenient wire connection point for external device control and test points (See FIGURE 2
for a detailed description of the contacts available).

NOTE: The DA-600 receiver will operate on 12 VDC. An auto battery with the positive (+) connected to the +24 VDC terminal
and negative (-) connected to the GND terminal will operate the DA-600. Therefore, the control panel can become portable (the
sensor is always portable) so the unit can be used in a vehicle or at a remote site.
NOTE: DO NOT PLUG THE UNIT INTO 110 VAC IF OPERATED ON BATTERY AS IT CAUSES FAILURE
