9.
Next, a wire passage hole will be required in the door header (Picture 15) and also in the jamb tube (Picture 16) at
approximately the same height as the Door Mounted Safety Sensor. The wire transfer hole in the jamb should be at
the secure side of the door. Normally this would be the interior side. Feed the wire through the jamb tube up to the
header. Insure that enough wire is left out to reach the Door Mounted Safety Sensor terminal block.
10. Once all cabling is in place, the plastic sheath must be installed over the wire coming out of the jamb tube. This must
be done before making final connection to the terminal block. The sheath may have to be cut to fit the application.
Once the wire is fed though, the plastic cap may be installed on the jamb, over the transfer hole.
1.
With cabling in place, wiring at the terminal connector on the DMSS master module (picture 20) may be completed.
Wiring will vary according to the application. Available positions on the connector are shown below:
TERMINAL
EXPLANATION OF WIRING CONNECTIONS
1 TST
TEST DATA - Used with SMR systems only.
2 GND
GROUND - Negative terminal if Input inhibition is used.
3 INH
INPUT INHIBITION - All detection is ignored. Infrared emission is stopped. Inhibition occurs
when 12 to 24 VAC ± 10% or 12 to 24 VDC + 10% is applied between terminal 3 and
terminal 2.
4 NO
In the relay mode, depending on the position of JP2 this terminal will provide either a NO or
NC contact. (JP2 factory default will result in NC on terminal 4)
5 NC
In the relay mode, depending on the position of JP2, this terminal will provide either a NO or
NC contact. (JP2 factory default will result in NO on terminal 5)
6 COM
COMMON - Contact for relay.
7 -
NEG. POWER - This terminal is used for power input. A voltage of 12 to 24 VAC ± 10% or
12 to 24 VDC + 10% must be supplied.
8 +
POS. POWER - This terminal is used for power input. A voltage of 12 to 24 VAC ± 10% or
12 to 24 VDC + 10% must be supplied.
NOTE: Ensure there is enough slack in cabling to allow adequate movement of the cable throughout the range
of door travel.
