INSTALLATION GUIDE
DOOR
CONTROLLER
The ADC-ACC1-17 Door Controller provides local decision
making, event reporting, and database storage capabilities
for the Alarm.com Smarter Access Control platform.
Two reader interfaces provide control for one supervised
physical barrier or two unsupervised physical barriers.
For UL compliance, the Power Sourcing Equipment (PSE), such as
a PoE enabled network switch and/or PoE power injectors, must be
UL Listed under UL294B.
Reader port 1 can accommodate a Wiegand reader and
provides LED and buzzer control. This port can alternatively
utilize a two-wire RS-485 bus to connect up to eight
Alarm.com expansion modules. Reader port 2 can
accommodate a Wiegand reader and provides LED
and buzzer control.
Two Form-C contact relay outputs may be used to control
locking hardware. The relay contacts are rated at 2A @
provided may be used for monitoring door position switches
as unsupervised or supervised. The ADC-ACC1-17 requires
Power over Ethernet (PoE) or 12V DC for power.
The ADC-ACC1-17 may be mounted in a 3-gang switch box;
on the provided mounting plate, or in an enclosure. The
supplied mounting plate has mounting holes that match
the ADC-ACX1 mounting footprint.
The SRAM is backed up by a rechargeable battery when input
power is removed. This battery should retain the data for
a minimum of 3 days. If data in the SRAM is determined to
cardholder data must be re-downloaded.
The initial charge of the battery may take up to 48 hours
to be fully charged.

RUNNING
Status LEDS
All LEDs OFF
LEDs 1, 2, 3, 4, 5, 6, and 7 are sequenced
during initialization. LEDs 1, 3, and 4 are turned ON for
approximately 1.5 seconds after the hardware initialization
has completed, then the application code is initialized. The
amount of time the application takes to initialize depends
on the size of the database, about 3 seconds without a
card database. Each set of 10,000 cards will add about 3
seconds to the application initialization. When LEDs 1, 2,

If the sequence stops or repeats, perform the Bulk Erase
If clearing the memory does not correct the initialization

Input Power
The ADC-ACC1-17 may be powered by one of two ways.
Use jumper J3 to select the input power source:
• Power over Ethernet (PoE) connection, fully compliant
to IEEE 802.3af, or
• Local 12V DC power supply wired to TB4-3 (VIN),
TB4-4 (GND)
Reader & Expansion Module Wiring
Reader port 1 can be used to wire either one Wiegand
reader or up to eight Alarm.com expansion modules.
Reader port 2 can be used to wire one Wiegand reader.
Power is supplied to reader port 1 at 12V DC at 180 mA
maximum. The reader connected to reader port 2 may be
powered from the 12V DC auxiliary power output; TB4-1
high current requirements should be powered separately.
cabling requirements.
Reader port 1 can support up to eight Alarm.com expansion
modules using a 2-wire RS-485 bus. The maximum cable
length is 2,000 ft. (610 m).
For readers with two LED wires, only connect the wire
controlling the green LED to the ADC-ACC1-17.
When powering expansion modules and peripherals from
the ADC-ACC1-17, be cautious not to exceed 650 mA @
12V DC. 22 AWG minimum recommended for readers.

Relay Wiring
Two Form-C contact relays are provided for controlling door
lock mechanisms. The relay contacts are rated at 2A @ 30V
pole (C), a Normally Open pole (NO), and a Normally
Closed pole (NC).
When momentarily delivering power to unlock the locking
hardware (fail secure), the Normally Open and Common
poles are used. When momentarily removing power to
unlock the locking hardware (fail safe), the Normally Closed
and Common poles are used. Check with local building
codes for proper egress door installation.
Door lock mechanisms can generate EMF feedback to the
relay circuit that can cause damage and premature failure
of the relay. For this reason, it is recommended that either
a diode or MOV (metal oxide varistor) be used to protect
the relay.
From the Auxiliary output, the ADC-ACC1-17 can provide
12V DC power for external devices, provided 650 mA is not
power supply is used, it must be UL Listed Class 2 rated. 18
AWG minimum recommended for electric locking hardware.

Input Wiring
Inputs are used to monitor door position switches or
unsupervised or supervised. When unsupervised, reporting
consists of only the open or closed states.
not only open and closed but also open circuit, shorted,
grounded*, and foreign voltage*. A supervised input circuit
requires two resistors be added to the circuit to facilitate
proper reporting. The standard supervised circuit requires
1k ohm, 1% resistors, and should be located as close to the
sensor as possible.
*Grounded and foreign voltage states are not a requirement of UL 294
22 AWG minimum required for input wiring. 18 AWG
recommended if wiring request-to-exit devices in series with
locking hardware.
