PRODUCT DESCRIPTION
The DX-COKIT is a DXS-80 carbon monoxide (CO) alarm with a
wireless transmitter that communicates with the matching DXR-
702 two channel receiver. The CO alarm monitors its operating
condition and the transmitter will send battery status to the
receiver. If the battery is low, the receiver’s channel two relay
will latch until reset. In the event of an alarm, the transmitter will
activate channel one of the DXR-702, and the receiver’s relay
will close for four seconds. IMPORTANT: When the DXR-702
is connected to a security panel it is very important that the
central station monitoring the location is advised of which
zone(s) will report a carbon monoxide alarm.
In a typical installation, the receiver is connected to an alarm
control panel. The receiver should be mounted with the
supplied mounting bracket indoors or inside a weather resistant
non-metallic housing.
Refer to the instructions for the DXS-80 CO alarm included with
this product for information about locating and mounting the DXS-
80. Please read the DXS-80 instructions thoroughly for important
information about the effects of carbon monoxide poisoning.
The digital DX code format features over a million possible codes.
The DX transmitters are precoded at the factory to unique codes,
so no fi eld coding is required. For versatility, any transmitter can
be programmed into any receiver channel. Receivers must be
programmed to the transmitter’s code before system testing and
operation. Up to 32 transmitters maximum can be programmed
into the receiver. The transmitters can be split in any number
between the two receiver channels.
The DXS-80 CO alarm is factory programmed into channel one
of the receiver that it boxed with in the DX-COKIT.
Receiver channel two is a special channel. If channel two memory
is empty, with no transmitters programmed into it, it will report
low battery signals from any channel one transmitters capable of
sending them. When a low battery transmission is received, the
channel two relay will latch. The relay will remain engaged until
the channel two program button is pressed. The low transmitter
batteries should be replaced before resetting the relay.
The receiver can be powered from a 11-17 VDC or 12-16 VAC
power source. The relays’ normally open and normally closed
contacts can switch up to 1 amp at 24 volts AC/DC.
A nine-inch wire whip antenna screws into the receiver’s antenna
connector. Optionally, a remote antenna (Linear EXA-1000) can
be connected to the receiver for greater radio range. The red
program indicator lights during RF reception. The installer can
verify that signals are being sent from transmitters and diagnose
interference problems by viewing the indicator. The indicator also
lights during memory programming/erasing and fl ashes to count
the number of transmitters in memory.

MOUNTING NOTES:
1. WHEN USING THE LOCAL WHIP
ANTENNA, MOUNT RECEIVER AS HIGH
AS POSSIBLE FOR BEST RADIO RANGE
2. WHEN USING THE LOCAL WHIP
ANTENNA, KEEP RECEIVER AWAY
FROM METAL OBJECTS THAT CAN
DECREASE RADIO RANGE BY
SHIELDING THE SIGNAL
3. IN ALL INSTALLATIONS, KEEP
RECEIVER AND ANTENNA AWAY FROM
MOTORS, FANS AND OTHER
ELECTRICAL DEVICES THAT MAY
CAUSE INTERFERENCE AND REDUCE
