Electric Lock
Relay
N.O. Dry contact – Contact closes upon activation. May be used for fail-secure locks by
routing 1 leg of power though the relay. Relay is triggered by activation inputs 10, 11, or
16. Relay remains energized until door is fully closed again.

Electric Lock
Relay
N.C. Dry Contact - Contact opens upon activation. May be used for fail-safe locks by
routing 1 leg of power though the relay. Relay is triggered by activation inputs 10, 11, or
16. Relay remains energized until door is fully closed again.

Door Status -
Closed
N.O. Contact is closed when door is closed. The contact opens as soon as the door
opens.

Common contact for door status
6
Door Status -
Open
N.C. – Contact is closed when door is open. The contact opens as soon as the door starts
to close. This input can be used for motor connection at lockout relay when power is
looped through, thus switching power on when door is open.

Activation
Requires N.O. Contact between input 10 & COM. Remains capable to activate when dip
switch 3 is ON AND On-Off switch is OFF.

External
Activation
Requires N.O. Contact between input 11 & COM.
12
Emergency
Closing
Requires N.C. contact between 12 & COM. Upon open contact, door closes and overrides
all other inputs. Remains jumpered if input is not used.
13
Secondary
Activation
Requires N.C. contact between 13 & COM. Disabled in full closed position.
14
“Stall” Safety
Requires N.C. contact between 14 & COM. Upon open contact, (Dip 6 OFF) during
opening, door stops, then resumes at reduced speed when input is released.

Alarm Input
N.O. contact, when closed causes door closing. All inputs inhibited during closed contact
(not available on all software versions)

Sensor Input
Requires N.O. contact between 14 & +24 VDC (input 9). When input is closed it causes an
open door to stay open and a closed door to stay closed. Works in conjunction with dip
switch #6.
