TruPortal Dual Door Interface Module
The Dual Door Interface Module TP-ADD-2D is capable of supporting two
complete door configurations, with up to two readers per door. This dual
door interface module provides termination points for door contacts (door
position switches) and request to exit devices as well as two door strike
relays to control power to the controlled access doors. It communicates to
the TruPortal family of system controllers (TP-SYS) via a 2-wire RS-485
bus.
The TruPortal Dual Door Interface Module is available in a board-only
configuration (TP-ADD-2D-BRD)
or pre-installed in a UL
or CE enclosure with or without bundled readers and credentials
(TP-ADD-2DR, TP-ADD-2D).

UL or CE enclosure with power supply (depending on option ordered)
•
Installation kit which includes:
-
Two positional terminal plug-in block (quantity = 5)
-
Three positional terminal plug-in block (quantity = 4)
-
Four positional terminal plug-in block (quantity = 4)
-
Six positional terminal plug-in block (quantity = 2)

Model Numbers
The Dual Door Interface Module is available in the following
configurations:
•
TP-ADD-2D-BRD (board only)
•
TP-ADD-2D (installed in UL enclosure)
•
TP-ADD-2D2R (installed in UL enclosure and bundled with 2
readers)
•
TP-ADD-2D-E (installed in CE enclosure)
Note:
-E model numbers are “Not Evaluated by UL” and therefore
cannot be used in UL installations.
Mounting the Module
If you are adding a TP-ADD-2D-BRD to an existing enclosure (e.g., a
TP-ADD-2D with available space) use the provided screws as required to
mount the unit in one of the designated enclosures.
Determine the series of eight standoffs for mounting the module. Insert the
module and mounting plate assembly and attach it with the eight nuts
provided.
Note:
Do not over-tighten the mounting screws.
Anti-attack Bushing Cap
If this module is being mounted in the same enclosure as the TruPortal
System Controller, or added to an existing enclosure of another
TP-ADD-2D unit, an anti-attack bushing cap covers a rear tamper spring. It
fits inside an O ring bushing located in the cabinet’s rear wall anti-tamper
spring knockout. Leave the O ring bushing and cap in place if the rear
tamper is not used.
If the rear tamper is used:
1.
Remove the cap and the O ring with the edge of a flat screwdriver.
2.
Discard the O ring.
3.
Align the cap for the tamper spring and knockout hole on the cabinet
back.
4.
Screw the cap into the mounting surface.
5.
Place the control cabinet over it, allowing the rear tamper spring to fit
inside the cap. The cap will fit into the cabinet’s tamper spring
knockout hole.
6.
Secure the cabinet to the mounting surface.
Wiring
Door Unlock Circuit: A diode is provided to protect against voltages
induced when a DC strike is de-energized. For an AC strike, or a magnetic-
lock with reversing coils (or if unsure), you must use a 27 V Metal Oxide
Varistor (MOV).
Verify that at least 10.5 VDC is at each device (with relays energized). Use
additional power supplies as necessary.
For large current-draw devices with built-in power supplies, connect the
incoming and outgoing module bus +12 VDC lines together, but do not
connect to the +12 VDC in the cabinet.
Output Wiring
The contact protection circuit must be used. The following two circuits are
recommended. Locate the protection circuit as close to the load as possible
(within 12 inches [30 cm]), as the effectiveness of the circuit will decrease if
it is located further away.
