Telewave PM5C1S Automatic Alarm Panel
The Telewave PM5C1S is an automatic alarm panel equipped with “true VSWR” circuitry. When paired with optional PM-1A or PM-2A power monitors, this panel can monitor the power output of up to five transmitters for low power conditions and provide a high VSWR alarm for a single antenna. The 3RU (5.25” x 19”) panel is designed to fit into any standard rack or most base station cabinets and can be powered directly from 120 VAC or 12 VDC.
The PM5C1S detects low transmitter power on any of the five channels and triggers a latched relay closure, activating a red light on the front panel for the affected channel. Each channel has both normally-open and normally-closed relay contacts for remote activation of lights, speakers, or other alarm systems. A high antenna VSWR condition is accurately detected across all power levels, triggering a sixth latched relay and light. These alarms can be reset via the front panel RESET button or by momentarily grounding the RESET input connection on the rear of the unit.
Additionally, the PM5C1S functions as an inline power monitor, measuring forward and reverse RF power for up to 5 transmitters, plus a sixth channel for the single antenna VSWR. All readings are displayed on a 3.5-inch meter. Up to 6 power monitors (sold separately) for the appropriate frequency bands are required. The panel is not frequency-dependent, allowing for use with multiple bands by installing the appropriate power monitors.
The PM5C1S offers two meter scale options: 0-250 watts or 0-400 watts. The meter scale must be specified when ordering.
