INSTALLATION AND
SPECIFICATION
General
The PRO42R1 reader interface provides a solution to the OEM system integrator
for interfacing to a TTL (D1/D0, Clock/Data), F/2F or RS-485 device, and door
hardware. It also provides a tri-stated LED control and buzzer control. Two Form-C
contact relay outputs may be used for strike control or alarm signaling. Two inputs
are provided that can be used for monitoring the door contact and request to exit
push button. Input circuits can be configured as unsupervised or supervised. Com-
munication to the controller is accomplished via a 2-wire RS-485 interface. The
PRO42R1 requires 12 to 24 Vdc for power.

PRO42R1 Hardware
The PRO42R1 requires filtered 12 to 24 Vdc ± 10% for power. Two inputs are typi-
cally used for door contact and exit push button monitoring. End of line resistors
are required input supervision, shown below.
Note: The input power is passed through to the reader terminal strip and is available for
powering a reader. Readers that require different voltage requirements must be
powered separately. Care must be taken to insure that the input voltage is within the
voltage range of the reader. The reader power output terminal, TB4-6 (VO), is not
current limited

Reader wiring
The reader port supports a reader with TTL (D1/D0, Clock/Data), F/2F, or 2-wire
RS-485 signaling. **Refer to the reader manufacture specifications for cabling
requirements. In the 2-wire LED mode the buzzer output is used to drive the sec-
ond LED. Reader port configuration is set via the host software. Do not terminate
any RS-485 device connected to the reader port.
Caution: : D1 to LED on supervised F/2f readers

Door Strike Relay Wiring
The PRO42R1 has two Form-C contact relays for controlling a door strike or other
devices. See specifications section for the relay contact ratings. Load switching
can cause abnormal contact wear and premature contact failure. Switching of
inductive loads (strike) also causes EMI (electromagnetic interference) which may
interfere with normal operation of other equipment. To minimize premature con-
tact failure and to increase system reliability, use the contact protection circuit
shown below. Recommend the following circuit. 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 far away.

PRO42R1 Installation Guide, Document 800-26500 5
Communication Wiring
The PRO42R1 communicates to a Honeywell Security intelligent controller
(EP2500 for example) via a half-duplex multi-drop 2-wire RS-485 interface. The
total cable length is limited to 4,000 feet (1,219 meters). Shielded cable of 24 AWG
with characteristic impedance of 120 ohm is specified for the 2- wire RS-485 inter-
face. The device on each end of the communication line should have the termina-
tor installed (install jumper J1 of the PRO42R1)
.

Address Baud Rate and Encryption Configuration Switch
Switches 1 to 5 select the device address. Switch 6 and 7 select the communication
baud rate. Switch 8 enables encrypted communication. All other configuration
settings are set via host software.
