The Multi-Door Controller is pre-wired to power 8 Doors with Door
Strikes.
If a door requires mag lock power instead, remove the link for the
door number strike and jump the previous door’s strike power to
the next doors’.
Example: Door 3 has a mag lock. Remove the pre-wired jumper
between door 3 and 4 and move the connection from 3 to 4 to
continue supplying power to the remaining doors.

Example: Door 3 has a mag lock. After its strike
power jumper has been bypassed, add a jumper
for its positive mag power. Supply mag power to
each door using a mag, in the same way.

Backup Batteries
Each power supply requires a separate battery. These may need to be smaller than 7 Ah
to fit into the cabinet. Exception: If you must share a battery between 2 P/Ss, insert a
diode in the BAT (+) connection to the second PS.

Ensure each cabinet is connected to
a locally-approved earth ground
using at least 18 AWG wire.
Do not connect anything else to the
earth ground.
Connect the Module Bus cable
shields together inside each cabinet
and only connect the shield to earth
ground at the ISM panel.
Grounding
Jumper
Strike and mag lock connections are pre-wired between the door
controller boards and the two large terminal strips near the bottom
of the cabinet. Module Bus connections are provided as well.
Other connections (such as reader cables, door contacts, etc.)
connect directly to the door controller boards.
For door-strike and mag lock instructions, refer to the "Power
Links" sections.

For "Fail-Safe" door strikes
(powered = locked), connect to the
large terminal strips as usual, AND at
each applicable Door Controller Unlock
Relay, move the N/O wire to N/C
