The Site Alarm Module (SAM) is an optional module that may be used with the Antenna System Monitor (ASM) to allocate a dedicated alarm output for up to ten (10) channels of the channels being monitored by the ASM.
Additional SAM’s can be easily added (daisy-chained) to increase the number of monitored channels with dedicated alarm outputs. The ASM will auto-detect the SAM module when 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 inhibit an alarm. Four (4) additional “general purpose” alarm inputs are available on each
SAM to monitor a combination of temperature, analogue voltage and digital input site alarms - such as site room temperature, battery voltages, 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 alarms. A mixture of SAMs and CAMs may be connected to one ASM if desired.

Features:

- User-assigned 10 Channel alarm relay outputs
- Auto detected (plug’n’play) when connected to ASM
- 10 Conditional PTT or general purpose digital input status monitoring capability
- Compact 1RU 19” rack mountable shelf
- Expandable - up to 10 SAM’s (and CAMs) may be connected to one ASM
- Enabling priority alarm reporting, providing a tigger as a Hot/Standby base station radio switch
- 4 additional, user configurable, general purpose temperature, analogue or logic alarm inputs
- Power and comms interfaces daisy chained from ASM
- Front and rear alarm relay activation notification LED’s
