A SMALL TIP TO HELP PROTECT
YOUR SA-1 DOOR SEQUENCER
SA-1 FEATURES:
SA-1 (MK5)
Locks such as maglocks and door strikes are
essentially large electro-magnets. When power
is removed from such locks, a high voltage is
generated by the collapsing magnetic field. This
voltage (called Back EMF or Kickback) will
eventually damage the relay contacts.
Fortunately, it is possible to virtually eliminate
these effects by simply connecting the proper
suppression device across the relay contacts.
This device is called a MOV (Metal Oxide
Varistor). Use the supplied 35 volt MOV with
either AC or DC power to the electric lock.

The SA-1 MK5 is a digital version of the MK4.
Because it is digital, we've been able to improve
its performance and add some requested features.
Timer setting is more accurate and you can now
use AC voltage for a hot trigger input reducing the
need for extra interface relays. The latest versions
of this product have improved noise immunity.
Latching Relay Option
A flick of a switch changes the SA-1 into a
Latching Relay. The 1st push of a button starts
the Sequencer cycle - the same as the other
modes. However, one or both relays will remain
on after the timers have expired until the button
gets pressed again.
With the latching relay operation triggered off the
momentary input, the extended trigger remains
operational. The activation of the extended trigger
overrides the latching relay so the relays won't
be latched on after the extended trigger ends.

The terminal strip provides access to the lock & operator
relay contacts, trigger inputs, and power connections.
The SA-1 Door Sequencer is a highly versatile
circuit designed to allow easy interface solutions
to a wide variety of door installation situations.
A single input can unlock and open a door, re-
engage the lock, hold the door open for an
indefinite period of time, and automatically close
and re-secure the door at the end of the trigger.
