RFI Site Alarm Module (Option For ASM)
The Site Alarm Module (SAM) is an optional module used with the Antenna System Monitor (ASM) to allocate a dedicated alarm output for up to any ten (10) channels being monitored by the ASM.
Up to ten (10) SAM's can be easily added (daisy-chained) onto one ASM to increase the number of monitored channels with dedicated alarm outputs. Site Alarm Modules (SAM) and Channel Alarm Modules (CAM)
may be mixed on one ASM if desired. The ASM auto-detects SAM modules when they are connected, and through the GUI (Graphical User Interface) of the ASM the user can configure which of the SAM outputs are assigned to respective ASM monitored channels. Conditional alarm status is a feature that allows the individual base station PTT lines to be compared with the ASM channel alarm status, allowing a "no RF output"
from the base station to be recognised and raise an alarm event. Four (4) additional "general purpose" alarm inputs are also available on each SAM to monitor site alarms - such as temperature, battery voltages, site access doors and other site conditions. Front and rear LED's provide a visual indication of the status of all 10 output and 4 input alarm states.
Features:
- User assigned 10-Ch alarm relay module
- Auto detected by ASM when connected
- Conditional PTT status alarm reporting
- Compact 1RU 19" rack mountable shelf
- Expandable to a total of 10 SAM's (and CAMs) per ASM - each monitoring up to 10 Channels
- Latched alarm outputs for Hot/Standby base station and Auto-Change Over antenna control
- Up to 10 user configurable, PTT activated or general purpose logic alarm inputs
- Up to 4 user configurable, general purpose temperature, analogue or logic alarm inputs
- Communications interface and power daisy chained between ASM and respective SAM's
- Front and rear alarm relay activation notification LED's
