5.
LCD DISPLAY
Backlit, 24-character-per-line, 2-line LCD display. Displays system
operation and programming information.
6.
RADIO RANGE KNOB
Controls the gain of the radio receiver. Used to limit the maximum
operating range of transmitters. Turn clockwise for more gain,
counterclockwise for less gain.
7.
ANTENNA INPUT
For connection to the EXA-1000 omni-directional or EXA-2000 directional
remote antenna.
8.
DATA ENTRY KEYS
Arrow keys are used to scroll through displayed menu trees. OK key is
used as an enter key to accept data entered or selected.
9.
RADIO INDICATOR
The RADIO light indicates the presence of RF signal into the unit’s
receiver.
10. NUMERIC KEYPAD
Used for entering data while programming the AM/II.
11. RS-232 PORT
Connects to a serial line printer, PC or data terminal for logging access
transactions. For local programming with a PC or remote programming
with a PC and a modem. Also used to interconnect two AM/II units to copy
the memory between systems.
12. POWER SWITCH
Controls the DC and AC power inputs. This is the master power switch
for the AM/II.
13. EARTH GROUND TERMINAL
For connection to a good earth ground. For electrical safety and optimum
lightning protection, this connection is mandatory.
14. POWER TERMINALS
DC power input terminals for 12 to 35 VDC. AC power input terminals for
14 to 24 VAC. Use either AC or DC power, DO NOT USE BOTH.
15. RELAY INDICATORS AND ACCESS BUTTONS
Indicators will light when an output relay is activated. Outputs can be
activated (open) by a transmitter or locked open by pressing an ACCESS
button.
16. EXTERNAL CONTROL INDICATORS
MAGIC WAND indicator lights when the special “MAGIC WAND”
transmitter is activated by a system administrator. OBSTACLE indicator
lights when a signal from a Model MGT safety edge transmitter is
received.
17. RELAY TERMINALS
Connects to the access device to be controlled (door strike, gate operator,
etc.). Open request switch inputs are provided for relay channels A & B.
18. WIRING STRAIN RELIEF HOOKS
Strain relief hooks are provided on the bottom of the AM/II case. After
wiring is complete, wires can be zip-tied to the strain relief hooks.
19. PERIPHERALS INDICATORS
The DECODE light indicates that the data being received is a valid format
that the unit recognizes. The ACCESS GRANTED indicator lights when
a device that is allowed to have access is triggered. The ACCESS IN and
ACCESS OUT indicators light when data is being sent or received from
the remote devices.
20. READER IN TERMINALS
Connects to remote accessory devices.
21. KEYPAD IN TERMINALS
Connects to remote accessory devices.
22. ACCESS OUT TERMINALS
AccessNet Data Bus for connection to other access control units. Sentex
access out format is programmable for connection to Sentex Infinity
systems. Wiegand26 and SecuraKey31 access out formats are
programmable for connection to Wiegand inputs on other access control
units.
23. NETWORK TERMINALS
For connection to other AM/II units. Up to 8 units can be networked
together.
