Low Voltage Inputs
Any EM1400 series relay panel may be used with
"digital" switches that sit on the data bus and are
connected with Cat. 5 cable with RJ45 connectors.
Additionally, one may order the EM1400 with the op-
tional contact closure inputs. These can be used with
contact closure devices - even ordinary wall switches
available from any hardware store.

This Product Guide does not contain system-wide
wiring or activation procedures. Please refer to
the System Start-Up Guide for system wiring and
activation details and for hook-up details to other
panels or digital devices.
The photocell input in the
Master LCP allows a pho-
tocell to be included in time
schedules. Up to 8 trigger
points are available for mul-
tiple schedules.
Contact Closure Inputs
14 programmable contact inputs can control any
relay(s) in any panel(s), for manual (on/off) or over-
ride.
Use shielded cable for distances over 150 feet.
Connect the drain wire to the GND input of the panel
only. Do not connect the drain wire to a remote
switch!

This system uses a fl oating ground - do not use
earth ground.
Cat. 5 cables for the

This maintained switch is
programmed as "maintain" in
the Button Sub-Menu for up
to 8 relays or as a Maintain
Group for more than 8 relays
(see Basic Programming
Guide).
Occupant sensors with isolat-
ed dry contacts may be used
to control relays or groups.
Set the timer on the occupant
sensor at the desired time
delay and program the input
as "maintain."

Center-Off momentary
switches are two separate
contacts, and use two inputs.
Program one as "momen-
tary on" and the other as
"momentary off."
Relay outputs from any exter-
nal system, such as security,
are usually programmed
EN
"maintained" or as "momen-
tary on" for a timer.
Momentary switches are
often programmed as "tog-
gle" or "momentary on" (for
an override switch). They
can also be "off" or "mixed
mode".
