OVERVIEW The RM-DCM-2 is a UL294 Listed and UL1076 Listed door control
module that includes the RM-4E Reader Module (RM-4E) and enclosure.
The RM-DCM-2 is designed to support up to two RM-4E modules,
providing a single enclosure for doors with IN and OUT readers.
The enclosure also has space for up to three I/8 and/or R/8 boards, for a
total of four boards. The RM-DCM-2 supports an optional battery (12
VDC, 4A), which will be recharged by the RM-4E battery charging circuit.
The RM-4E board provides the hardware interface between Magnetic
signaling read heads or Wiegand signaling read heads and the apC/8X,
iSTAR, and iSTAR Pro hardware. The RM-4E also provides inputs and
outputs that communicate between door components and the apC/8X,
iSTAR, and iSTAR Pro hardware.
The I/8 module provides eight supervised inputs and the R/8 module
provides eight dry contact, Form C relay outputs.
The RM-DCM-2 system consists of two subassemblies:
Model RM-DCM-CAN enclosure
Model RM-4E board
NOTE For information about the RM-4E, I/8, or R/8 modules, refer to the Quick
Start guides listed in Table 13.

Power In There are two ways to power an RM-4E:
Method A - from the Power In connector using an external power
supply, which also charges the battery through the BATTERY
connector.
Method B - from the RS 485 connector using the apC or iSTAR power
supply.
NOTE: Do not use both power connection methods at the same time.
NOTE A UL Listed power-limited access control or burglar alarm power supply,
capable of four hours standby, must be used when the unit is powered
from a source other than the apC or iSTAR.
FIGURE 6. RM-4E Power Wiring - Method A
Method A - via Power In
Connect +12 or +24 VDC to Pin 2 of the Power IN connector.
Connect the ground side of the supply to either Pin 1, 3, or 4. Because
the three grounds are all tied together, you can connect the negative
side of the supply to any of the three pins.
Do not use +24 VDC unless all devices on the bus are RM-4Es.
RM-4s, I/8s, R/8s and MRMs must be powered with +12 VDC.
NOTE The battery charger only works if you power through the Power IN
connector.
+12/24 VDC

Method B - via RS-485 (RM Bus Connector)
Connect +12 VDC to Pin 1 of the RS-485 connector on the bottom
right side.
Connect Ground (Gnd) to Pin 4 of the RS-485 connector.
NOTE The +12 VDC input on Pin 1 has a protection diode that prevents you
from using the RS-485 connector as a source of +12 VDC if you power
through the Power IN connector.
Battery
Connect the plus and minus sides of the 12 VDC battery to the Battery
connector. The battery provides power for memory retention in the event
of a power failure. When power is restored, the battery is charged by the
power supplied through the Power In connector.
LED Connector Table 2 lists LED Connector Signals and Functions on the RM-4E board.
NOTE UL has not evaluated using Pin 5 to drive an external beeper.
Typical LED Scenarios
One wire Bi-Color - Attach the brown wire from the read head to the
Yellow LED drive on the RM-4E.
Two wire Red and Green - Attach the brown wire from the read
head to Red LED drive. Attach the orange wire from the read head to
the Green LED drive.
Three wire Red, Green, Yellow - Attach each LED drive to the
associated color LED.

RS 485 Reader Bus RS 485 is the reader bus connection to the apC or iSTAR.
It is two wire, half duplex RS 485.
Connect Tx+ / Rx+ to Pin 2 and connect Tx- / Rx- to Pin 3.
The pins are numbered right to left on the connector.
Connecting Read
Heads
Connect read heads to the Read Head connector.
Connect either a Wiegand signaling device or a magnetic (ABA)
signaling device. Wiegand signaling uses Data 1 and Data 0 lines and
magnetic signaling uses Clock and Data.
Wiegand Signaling
For Wiegand signaling, use the following pinout; set SW5-1 to ON.

Magnetic (ABA) Signaling
For Magnetic (ABA) signaling, use the following pinout; set SW5-1 to
OFF.
NOTE UL has not evaluated magnetic (ABA) signaling read heads.
Relay 1, Relay 2,
MagLock, and Bypass
The RM-4E provides lock components that facilitate connecting magnetic
and electric strike locks.
Relay 1 is a standard Form C, dry contact relay, identical to the relays
found on the iSTAR ACM.
Relay 2, along with the MagLock and Bypass connectors have
internal etch connections for wiring magnetic and electric strike locks
Tie Point (TP1/TP2) connector pins are not connected to the circuitry.
They are used as connection points to avoid field splices when
connecting locks to Relay1. TP1-1 is tied to TP1-2, and TP2-1 is tied to
TP2-2.

LOCK WIRING
CONFIGURATIONS
RM-4E lock connectors support the following wiring configurations:
Magnetic Lock using Relay 2
Electric Strike using Relay 2
Electric Strike using Relay 1
The following sections describe how to connect each configuration. The
electric strike examples are shown as Fail-Secure.
Magnetic Locks The normal state of a magnetic lock has current flowing through an
electromagnet on the lock that pulls a strike plate with a force of 500-2000
lbs.
Safety codes usually require a bypass switch for emergency egress. This
is not the Request to Exit (REX) switch.
Note the internal etch connections between Relay 2, Maglock, and the
Bypass connector.
Connecting a Magnetic
Lock
The following figure shows an example of connecting the power supply,
magnetic lock, and bypass switch.

Lock Wiring Configurations

FIGURE 8. Magnetic Lock Wiring with Jumper Options

Lock Wiring Configurations

Magnetic Lock
Components
This section describes the components and connections for magnetic lock
wiring.
Power Supply
The power for a magnetic lock must be filtered, regulated direct current
(DC) voltage. Alternating current (AC) does not work and half wave
rectified DC does not work reliably.
Most magnetic locks consume about 3 watts, which is about 125
milli-amps @ 24 VDC or 250 milli-amps @ 12 VDC.
18 AWG wire is generally recommended. If the wire runs exceed 100 feet,
use 16AWG wire instead.
The power supply to a magnetic lock must be isolated. Do not connect the
output of the power supply or the negative side of the lock to earth
ground. The connection from the minus side of the power supply must
go to Maglock pin 3.
Bypass Switch
Connect a normally closed (NC) emergency Bypass switch as shown.
Remove the J15 Bypass jumper for normal operation.
It will be necessary to connect the J15 Bypass jumper (closed) if you install
an electric strike on Relay 2.
Diode Protection
An optional inductive kickback suppression diode is available by
connecting the J13 Diode jumper (closed).
Some magnetic locks have the suppression circuitry built-in so in some
cases the J13 Diode jumper should be removed (open).
RM-4E Power Failure
When using the configuration shown, the magnetic lock remains locked
if the RM-4E loses connection to the apC or iSTAR because the normally
closed (NC) connection of Relay 2 is used. The magnetic lock also remains
locked if the RM-4E loses power.

Lock Wiring Configurations
16
You have the option of wiring to the normally open (NO) connector of
Relay 2 if you want to have the Magnetic lock unlock under those
conditions. If you use the normally open (NO) connector then Relay 2
will have to be normally energized using the C•CURE Administration
application.
If the power supply fails, the magnetic lock will unlock regardless of
whether the normally closed (NC) or normally open (NO) is used.
Electric Strikes Unlike magnetic locks, electric strike locks typically lock when not
powered and unlock when powered.
You must decide if you want to wire for “fail-secure” or “fail-safe.” Fail-
secure means that if there is a power failure, the door goes to a secure or
locked state. Fail-safe (fail-open) means that the door is open if there is a
failure. It is important that local codes be followed to avoid people
getting trapped in an emergency situation. Usually fail-secure doors have
crash bars to allow emergency egress.
Using Relay 2 for an
Electric Strike
The same internal connections that are used for a magnetic lock can be
used to wire an electric strike. Connect the plus side of the power supply
to the normally open (NO) connection of Relay 2 and connect the
remaining external connections the same as the magnetic lock

Electric Strike
Components
This section describes components and connections for electric strike
wiring using Relay 2.
Bypass Switch
Connect the J15 Bypass jumper (closed) to provide the internal
connection from Maglock Pin 1 to the C contact of Relay 2. Do not connect
an external bypass switch.
Diode Protection
An optional surge suppression diode is available by connecting the J13
Diode jumper (closed). If the electric strike has a suppression diode built-
in, disconnect the J13 Diode jumper (open).
Using Relay 1 for an
Electric Strike
Relay 1 is a standard Form-C dry contact relay. Wiring door strikes using
this relay on the RM-4E is the same as wiring them to apCs, iSTARs, R/
8s etc.
Two pair of isolated tie points have been added to minimize splices.
Connect the strike and the power supply as shown. There is no
internal etch to consider when using Relay 1.
In the example below, a fail-secure door is shown with the normally open
(NO) contact. You can add an optional external suppression diode, if
desired.

NOTE To comply with UL requirements, use shielded, minimum 22 AWG
stranded, twisted pair cable for monitor points, DSMS, and REXs. Use
Belden 9462 or equivalent.
LED Input Status
Each input uses a Red, Yellow, or Green LED to show the input status.
Only one color will be on at a time for each input.
Table 6 lists the LED color and the corresponding input status.
Red LED indicates alert (nominal 500 ohms or 2K ohms).
Green LED indicates secure hardware state (nominal 1k ohms).
Yellow LED indicates supervision error (open circuit, shorted, or line
fault).
The RM-4E input status LEDs show flashing status if the RM-4E is
communicating with the apC or iSTAR and at least one input or
output is configured, or the reader is being used on a door. (The apC
or iSTAR needs a configured reason to communicate.)
