OPERATION OVERVIEW
Standard Operation
When a valid transmitter, entry code or card code is detected by the
system, the control will activate the programmed relay output. If the
AM/II is connected to a printer, a message is sent giving the code
number, the time of activation, device and network number and relay
activated.
The system’s clock has built-in battery backup to keep the time
accurate during power loss. The time is displayed in 24-hour format.
Suspending media codes allows the system administrator to deny a
user’s access without removing their information from the system’s
memory. Reactivating the media code allows the user to again have
access.
Transmitters, cards and entry codes that are lost, stolen or need to be
exchanged can be manually deleted from the system.
Manual Operation
The access outputs can be manually activated from the ACCESS
buttons on the AM/II. This is useful for maintenance personnel during
setup and testing. Pressing any of the access buttons will latch its
corresponding relay output and light its LED indicator. Pressing the
button again will unlatch the relay output and turn off the LED.
Magic Wand Transmitters
Up to eight MDT-4 four-button transmitters can be programmed as
“Magic Wand” transmitters. They allow maintenance personnel to
remotely lock the relay outputs open or closed for Channels A & B.
When service is being performed on a gate, maintenance personnel
will want to lock an output closed to prevent users from activating the
device. With a Magic Wand transmitter, the device can be disabled
remotely without having to disconnect the operator from the AM/II.
When service is being performed on a door with a door strike,
maintenance personnel might want to lock an output open to
constantly unlock the door during service.
When programmed as a Magic Wand transmitter, the MDT-4 buttons
function as follows:
WHITE BUTTON: Locks Channel A open (relay activated).
GREEN BUTTON: Locks Channel B open (relay activated).
YELLOW BUTTON: L o c k s C h an n el A c lo s e d ( r elay
de-activated).
RED BUTTON: Locks Channel B closed (relay de-activated).
TOP BUTTON: Resets the AM/II.
Obstacle Transmitters
One or two MGT safety edge transmitters can be used with the AM/II.
Obstacle transmitters #1 and #2 can be programmed to activate any
of the four relays.
When a safety edge connected to an MGT transmitter is triggered, the
appropriate output relay will activate, causing the operator to perform
an “obstacle cycle”.
The MGT safety edge transmitters are fully supervised. Every
hour they automatically send a status report to the AM/II. If the
MGT has a low battery or the cover is tampered with, unique
signals will be sent to the receiver. Trouble is indicated by a
flashing OBSTACLE light on the AM/II. If the relay output is set
to latch, it will latch only when there is trouble (it will be a timed
output with a normal obstacle signal). The systems LCD display
will state what the trouble is. If connected, the printer will log
the trouble. To clear the trouble indication, press # and 1.
