The electric latch retraction sequencer module may be used with any Hager latch retraction system such as the
Hager 4501 ELR or the 4501 MLR, any Hager electric strike, or any Hager maglock to provide a delayed signal to
operate an automatic door operator or when powering a pair of exit devices from a Hager 2909 power supply.
The two sequencer channels may be operated as two independent doors or in tandem mode for pairs of doors.
Each sequencer channel provides dry output for powering the exit device and a “delayed” dry auxiliary output
for activation of an automatic door operator. All outputs are field selectable as Normally Open or Normally
Closed.
When the Electric Latch Retraction Sequencer 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 .
SEQUENCER OPERATION:
