INSTALLATION INSTRUCTIONS
MODEL EMC
ELECTRIC LATCH RETRACTION SEQUENCER MODULE
The EMC dual channel sequencer module may be used
with the S6000FE and S6000PE series Electric Latch
Retraction device to provide a delayed signal to operate
an automatic door operator or when powering a pair of
devices from a single SDC 600 series power supply.
Each of the two sequencer channels provide a voltage
output to power an ELR device and a “delayed” SPST
dry auxiliary output for activation of an automatic door
operator. Each of the two sequencer channels may be
operated independently or in tandem mode for pairs of
doors.
When the EMC is used in the tandem mode, power
supply requirements for a pair of doors are minimized.
Since the attached electric latch retraction devices are
powered in a sequential manner, the inrush current of
each device is staggered. This creates a lower current
requirement upon activation. A smaller power supply
can now be used to operate the pair of devices .

DOOR OPERATOR
OUTPUTS (OPT) Isolated relay contacts provide a delayed signal
to activate the automatic door operator.
FEATURE
JUMPERS Select Single or Pairs of Doors activation.
Select time period to delay operator activation
ACCESS
CONTROL
INPUTS A momentary closure will retract the latch. The
device will release after the input is removed
and the operator activation delay period has
expired.
STATUS
LED’S Provides a visual indication of the device latch
status and time delay status
OPERATOR
ACTIVATION
PERIOD ADJ. Adjust to control the length of time that
the operator output relay activates.
