> Over Temperature Alarm (UHF 10 Watt system only, activates if Heatsink

temperature exceeds 60°C)

The user is able to assign either a high or a low priority to each of these alarms. When a

high priority alarm occurs, an opto-isolated output closes. When a low priority alarm

occurs, a second opto-isolated output closes. In either case, an alarm message is sent out

of the LMS port.

If a high priority alarm is triggered, a link set-up is attempted (if a link is not already in

place) and the alarm transported to the remote end. At the remote end, and any

intermediate repeater sites, the high priority output is activated and an alarm message is

sent out to the LMS port. At any site, the user is able to scroll through active local and

remote alarms via the front panel LCD.

When any alarm event occurs, local or remote, the alarm LED on the front panel flashes

red. When the user acknowledges the alarm using the front panel, the LED stops flashing

but continues to glow red.

4.4.1 Acknowledging an Alarm

To acknowledge an alarm, follow the menu path:

Enter Password→Alarms→Current Alarms

Use the up and down arrow keys to

scroll through the current alarms until the

new alarm is displayed. This is

recognisable by the flashing * in the

bottom left corner.

Press ‘Enter’ to acknowledge the alarm.

Note: To view the time and date stamp of the

alarm toggle the left or right arrow key.

When the alarm clears, the front panel LED extinguishes. If more than one alarm is

present at one time, the above conditions apply until all alarms are acknowledged, and

then cleared.

Alarm events (either activating or clearing of any local or remote alarm) are stored in a log.

Each entry includes a time and date stamp. The user is able to scroll through the alarm

log.

Note: The alarm log can hold 32 events. When the alarm log is full, the oldest alarm is

overwritten. In the event of a power failure, the alarm log will be lost.

4.4.2 Setting Alarm Priorities

To set Alarm Priorities (high or Low), follow the menu path:

Enter Password→Alarms→Priorities

Any remote alarm(s) will be cleared whenever the link closes down, either by a user-action or a link failure.
