Installation Instructions

The LRD41C-CONNKIT is required to enable alarm and auxiliary functions of the
receiver/driver.
The LRD41C-CONNKIT consists of
two
9-pin mating connectors that interface
with the LRD41C21/22-* 18-pin header as shown below. One 9-pin connector is
pictured at left. Two 9-pin connectors, which comprise the CONNKIT, are shown
below with their respective pin outs and functions when mated with the 18-pin header.
NOTE:
The Alarm Out signal
(pin 10, capable of 25 mA sink-
ing max.) is intended for logic
circuits or other low-power de-
vices. If you connect a device
that draws more current than
the maximum allowed, you
could destroy the output cir-
cuitry . If you wish to operate a
device that requires greater
current, then interface it with
a relay.

will sequence between the alarm presets. Up to eight presets
can be activated by alarm contacts connected to the receiver.
Any of these alarm inputs would activate an external device
through an open collector output.
AUX’S-The LRD41C21/22-* is capable of operating up to two
remotely activated auxiliary functions. Aux 3 is not available.
Aux 4’s logical output is dedicated to wiper control inside the
Legacy® enclosure.
