PassPoint Door Control Module
INSTALLATION INSTRUCTIONS
General Information
The Door Control Module (DCM) is used to control access points, or doors. When connected
between door hardware and the Main Logic Board, the DCM accepts data from card readers
and/or keypads, and operates the electromagnetic devices used to lock and unlock the door. The
DCM mounts in a standard cabinet and communicates with the system’s MLB via a twisted pair
network connection.
Each DCM provides all the inputs and outputs necessary to manage two single-reader access
points or one two-reader access point.
Power Requirements
When mounted in a cabinet with a dedicated power supply, the DCM obtains its power from the
LOCAL (J1) power output connection of its associated power supply. When added to a cabinet
along with an MLB or other module, the DCM obtains power from the power supply’s
REMOTE (J5) power output.
The DCM board requires 10.5-14VDC @ 170mA, but its actual current requirement will be
determined by the addition of the current requirements of two card readers (or keypads), which
are typically 90mA each. The DCM also provides two power supply monitoring inputs: Low
Battery and AC Loss. These two inputs are compatible with the corresponding monitoring
outputs of the PassPoint PTDPSU power supply only. (Do not enable AC or Low Battery
monitoring without first wiring the power supply.)
DCM Relay Outputs
In addition to card reader inputs, each DCM has two Form C, voltage-supervised output relays.
These relays are used to operate electromagnetic door locks or doorjamb mounted lock strikes.
Use appropriate transient suppression for the installed locking devices.
All DCM relays may be used as committed resources to control access points. For instance, one
of the operating parameters that can be configured for DCM relays is the length of time that the
relay output is energized when allowing entry or exit through an access point. DCM relays
cannot be commanded ON or OFF when used as a committed resource. Instead, the access point
these relays are assigned to must be bypassed or locked.
The relay output circuitry provides for a supervision input (30VRMS or 30VDC max.) which,
when connected to the common contact of the relay, indicates that a voltage of more than
approximately 4VDC or 4VAC is present at the relay contacts. The supervision input is rectified
and filtered before going to the comparator, therefore DC & AC voltages can be supervised. The
module's firmware doesn't know or care if the voltage is DC or AC. This supervision can be
useful to determine if the power supply that is used to power a connected load is fully
operational. Each relay can be programmed to monitor the relay contact voltage or to ignore it.

Installing the DCM in a Cabinet
There are two basic ways in which DCMs
can be mounted in system cabinets. The
first way is to mount the DCM in a
cabinet along with a power supply and
another module (MLB, QRM, etc.). In
this case, the DCM mounts on top of the
other modules on standoffs, as shown in
Figure 1.

MLB
If there is an MLB or other module in the
cabinet, the DCM gets its power from the
power supply’s REMOTE power output,
J5. The MLB will get power from J1.

DCM and power supply
Alternatively, a DCM can be mounted in a separate cabinet with a dedicated power supply. In
this configuration, the dedicated power supply provides power to the DCM from its LOCAL
power output, J1. But it can also provide power to another DCM through its REMOTE power
output, J5. Therefore, another DCM can be mounted in the cabinet. The second DCM mounts
on top of the first DCM on standoffs.
Mounting the DCM on another module
This procedure assumes you have already mounted a power supply and another module (e.g. a
QRM) in a system cabinet. For this discussion, we will assume you are mounting the DCM to a
QRM.
1. Secure six standoffs to the QRM using hardware provided.
There are holes in each corner and center of each PassPoint module to accommodate
standoffs. Standoffs are secured to the modules using screws and lock washers.
2. Position the DCM on top of the QRM standoffs and push down gently. Pushing down on
the DCM will lock it onto the standoffs.
Mounting the DCM without another module

Each DCM you mount must have access to
power from a PassPoint power supply.
2. Hang three black mounting clips (provided)
on the three middle raised cabinet tabs.
3. Insert the top of the DCM into the slots at the
bottom of the power supply’s mounting tabs.
4. Swing the base of the DCM into the
mounting clips and secure the board to the
cabinet.

NOTE: Ground terminals are

requires a power or signal
return line.
NOTE: Use orange lead for GREEN LED signal (LEDRDRA or
LEDRDRB) on some HID readers. All other readers use brown
lead. Check the label on your reader for proper GREEN LED
connection. Connect reader(s) to 5V or 12V per manufacturer's
voltage specification.
DCM LEDs
Red:
On when associated relay is energized.
Yellow: Blinks for 1 second during enrollment process. If this LED blinks or is on at any other
time, there is a hardware problem. However, expect this LED to blink briefly when
power is applied.
Green: Three blinks = OK. Any other pattern indicates hardware problem.
Enrolling and Configuring the DCM
Once the DCM has been mounted and connected, it needs to be enrolled into the system and
configured. Refer to the PassPoint Express Installation and Setup Guide (N8949) or the
PassPoint Plus Installation and Setup Guide (K4879) for information on enrolling and
configuring Door Control Modules.
