Location selection
Choose a dry, clean surface to install the ARX-50, giving consideration to
the importance of the location. The user must be able to see the visual
alarm and hear the audible alarm.
CAUTION: When using the included antenna, the ARX-50 must be
mounted vertically and the antenna must not be within 0.5 m of a metal
panel or other metal objects.
Ship's power requirements
The ARX-50 accepts ship's power supply in the range of +10.5 to +28 V
DC. A two-wire connection (ground negative) is required that is capable of
supplying 120 mA average and up to 400 mA under an alarm condition at
+10.5 to +28 V DC.
SECTION 3 - INSTALLATION
Mount the bracket
After selecting the location, hold the ARX-50 bracket in position and use as
a template to mark where the screws will be located.
CAUTION: When mounting to a wall, avoid mounting to metal.
Pre-drill holes of a smaller diameter than the screws, if appropriate for the
material that the bracket will be attached to.
Holding the bracket in place, screw the four supplied screws through the
openings in the bracket to the mounting material, securing the screws
tightly enough to allow for vibration, yet loose enough to avoid cracking the
case.
Snap the ARX-50 into its bracket vertically, antenna skyward. Double-check
that the ARX-50 is seated and secure by manually testing it for stability.
Install the monopole antenna
Install the monopole antenna on the ARX-50 via the BNC connector. The
open end of the antenna is attached to the connector by a clockwise
motion. The antenna snaps into place, locking it.
CAUTION: Proper installation of the monopole antenna is required to
seal the ARX-50. If any antenna other than the included monopole antenna
is used, the unit may not seal properly.
