HDMI Modulator from FTE Maximal Spain, suitable for sending Foxtel and...
The kit is a functional match to the LBB 1996, which duplicates the voice alarm controller. The Plena voice alarm remote control panels allow the system to be controlled remotely from one or two remote locations. There are five models available.
The Plena voice alarm remote control panels allow the system to be controlled remotely from one or two remote locations. The kits are a functional match to the remote control and the RC extension, with connectors on the front panel instead of controls and indicators.
The Plena Voice Alarm Router is an expansion unit that can add six zones and 12 input contacts to the Voice Alarm System. It can use the built-in amplifier on the LBB 1990/00 Voice Alarm Controller, and provides inputs and outputs for one or two amplifiers in a multi amplifier one or two-channel system.
The Plena Voice Alarm Controller unit is the heart of the voice alarm system and has full system supervision, loudspeaker line impedance supervision, a supervised emergency microphone on the front panel and a supervised message manager. Messages can be merged to allow even more flexible use of pre-recorded announcements and evacuation messages.
The Plena voice alarm remote control panel kit is a functional match to the LBB 1997/00, which duplicates the voice alarm router. All controls and indicators are available on screw terminals. Plena voice alarm remote control panels allow the system to be controlled remotely from one or two remote locations.
A Plena end-of-line board is a PCB designed to detect the 20 kHz pilot tone generated by a supervised public address or voice alarm system. It activates a voltage free switch in the presence of a 20 kHz signal (pilot tone) above 5 V, as well as an LED for easy visual confirmation of operation.
The Plena Voice Alarm System employs a simple and easy to use method of loudspeaker surveillance based on impedance measurement. On long wire runs, external influences, such as cable capacitance and speaker impedance, can negatively influence the reliability of the measurements. The dummy loads provide a filtered load exclusively at the pilot tone frequency.
