2-Zone Remote Alarm
(ARA)
Included Items:
• 4 mounting screws
• 1-inch connecting wire
• 3 AAA batteries
• blank labels
Setup and NO/NC Configuration
The Remote Alarm requires three AAA alkaline batteries for operation
(batteries included). Before installing the batteries, the Normally
Open/Normally Closed (NO/NC) jumper must be in the correct
position.
The NO/NC jumper configuration is only checked when the batteries
are installed. If the jumper setting requires changing, the batteries
should be removed then reinstalled after the change.
Remove the four screws in the back of the case with a Phillips-head
screw driver. There is a jumper strip labeled NO (Normally Open) and
NC (Normally Closed) near the top of the board (see Figure 1). The
jumper is in the NC position when shipped from the factory. Put the
jumper in the position corresponding to the alarm output
characteristics of the device to which the Remote Alarm will be
connected. Normally Open operation is used with alarm contacts that
are normally open and closed in alarm conditions. Conversely, Normally
Closed operation is used with alarm contacts that are normally closed
and open in alarm conditions. The jumper setting applies to both zones;
they are not individually selectable.

The Remote Alarm is a battery-powered remote alarm device with audio and visual alarm indications. The Remote
Alarm is compatible with alarm outputs having passive relay contacts.
IMPORTANT INSTRUCTIONS FOR USE: THE REMOTE ALARM IS NOT INTENDED FOR AND SHOULD NOT BE USED IN
APPLICATIONS INVOLVING LIFE THREATENING OR LIFE SUPPORT SITUATIONS.
The ARA Remote Alarm does not operate without working batteries. Alarm function will not work if the batteries are
removed from the unit, or if the batteries fail. Please check the batteries and test the alarm function regularly.
Although the ARA and all its parts have passed all factory tests and are designed to be as reliable as possible, any of
these parts could fail at any time.

Audio Beeper Volume
The beeper volume can be adjusted by moving the jumper on the
jumper strip labeled LOUD and SOFT (see Figure 1). The jumper is in the
loud position when shipped from the factory. If no beeper indication is
desired, the connector plug attaching the beeper to the circuit board
may be disconnected.
Zone Connection
Using a small (jeweler's) regular flat head screwdriver, loosen the
screws for the desired zones on the screw terminal block and insert the
interconnect wires. Then tighten the screws until a moderate tug does
not pull the wires loose.
If you are using only one zone and are in the Normally Closed (NC)
mode, a jumper wire must be installed into the unused channel;
otherwise that zone indicator will always be flashing and will
significantly diminish the expected battery life.
Connecting Multiple Logger Alarm Outputs into a Single
Zone Input
You can connect multiple logger alarm outputs into one zone input as
long as they are all of the same type (NO or NC) and are connected
properly. The connections depend on whether the devices are NO or
NC.
