TruPortal Dual Door Interface Module Quick Reference 3
Output Wiring
The contact protection circuit must be used. The two circuits
shown in Figure 2 and Figure 3 are recommended. Locate the
protection circuit as close to the load as possible (within 12 in.
[30 cm]), as the effectiveness of the circuit will decrease if it is
located further away.

Figure 3: Recommended Circuit #2
Magnetic Locks and Other “Fail-Safe” Door Locks
The default door lock wiring is for “Fail Secure” (powered =
unlocked). For magnetic locks and other “Fail-Safe” door locks
(powered = locked), move the Normally Open (NO) wire to
Normally Closed (NC) terminal for the specific unlock relay.
Note: The System shall not be installed in the Fail Secure
mode unless permitted by the local authority having
jurisdiction and shall not interfere with the operation of
panic hardware. (Not evaluated by UL.)
