Siemens LVM — supervised live voice microphone module for FireFinder XLSV emergency voice alarm systems.
When a recorded evacuation message is running and the incident commander needs to say something the message cannot, the LVM takes over the selected audio zones. The microphone element and the push-to-talk switch are both supervised, so a failed mic reports as a trouble rather than during an event. A built-in speaker monitors the channel before keying up.
- 24 V standby current 51 mA max, plus 1 mA per active LED; backplane current 0
- CAN pair 8 V peak-to-peak max, 75 mA max during transmission; 120 Ω termination each end
- Six switches and six LED pairs; rear rotary decade address switches
- Mounts to the inner door of a CAB-1, CAB-2, CAB-3, REMBOX2 or REMBOX4
- Five LVMs max per DAC-NET/LPB; 99 CAN modules max per DAC bus
Each LVM ships with one CCL CAN cable only; the 24 in. audio cable (P/N 555-134260) is a separate part number. In a REMBOX2/4 the OCM-16 and SIM-16 cannot be used.
