• Automation: Red Led - Indicates that the Alarm Automation process is

unable to get Acknowledgements from a designated alarm monitoring

system.

• 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 7705i.

3.1.4 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 Figure 3-3

. 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 Sounder: 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.

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, press the Power Button on

the front panel for 10 seconds or 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.
