RF Interference:
Red Led - Indicates that an RF interference condition exists
and that signals may be hindered. RF interference is a condition where the
Carrier Detect (CD) in the transceiver is active for more than 20 seconds. This
LED will turn off if CD turns off for 100 milliseconds.
Power: Green Led -
Indicates that proper power is detected at the monitored
points within the 7705ii.
3.1.3 Alert Panel:
This section of the front panel contains an LED and two Push
Button Switches. The LED illuminates to indicate the existence of unacknowledged
message(s). The switches allow for Silencing and Acknowledgment as described
below: See
. There is also an audio device associated with these functions,
which is located behind the small hole to the right of the Alert Panel.
A message queue exists within the MultiNet receiver to hold messages that are in need
of a user’s response. A user must acknowledge these messages manually when alarm
automation is offline and that automation system is not acknowledging the reception of
those messages using the configured communication protocol.
Tactile Response
Sounde
r
:
A short beep sound will be heard from the tactile
response sounder located near the LCD any time a button press in this panel is
accepted. There may be a short delay between the press and the sounder’s beep.
Silence Button:
Is used to silence the internal alert sounder.
Note:
The
Silence button when held down for a minimum of 5 seconds will start the
LCD test and LCD lamp test sequence.
If the Silence Button does not silence the Alert Sounder,
it may be due to an
overheating condition. Other MultiNet Receiver functions may appear normal. The
unit must be shut down and the cause of the overheating condition must be corrected
before continued use. To shut down the unit, switch the power switch on the rear panel
to the Off position. Contact AES for service
Alert LED: Red Led -
Indicates that a condition
exists that needs attention or that the CPU LED is on.
Refer to the Alert messages on the LCD display for
details.
Acknowledge Button:
Is used to Acknowledge the
message that is currently displayed on the LCD
Display. This is a function that is only required when
automation is offline. Once acknowledged the current
message is removed and the next message (if any) in
the message queue is displayed.
When alarm automation is online, pressing this button will turn an illuminated
Alert LED off.
