Description
This industrial master station is a waterproof model designed for humid, dirty and outdoor conditions. The unit can operate in an ambient temperature range from -20oC to +50oC (-4oF to +122oF). The station consists of a rugged splashproof and chip-resistant casing of orange makrolon and has a folio keyboard on the front. The front panel is hinged to the back casing to allow easy access during installation and service. The station has screw terminals with labels for easy installation. Two glands ensure waterproof and dustproof connection of installation cable and loudspeaker wires.
The unit is equipped with a noise cancelling microphone preventing background noise from disturbing the conversation. A 20-70 Ohm external loudspeaker connects to the station or, alternatively, connect an 8-20 Ohm speaker for use with the built-in 10W (8 Ohm) VOX operated power amplifier. The external speaker must be placed at least one meter away from the station. The power amplifier requires separate 12V AC / 2 Amp power supply.
The loudspeaker volume is adjustable with potentiometers located inside the casing and the station is programmable for permanent private mode by strap-plug setting inside the station.
The station is prepared for connection of a separate external handset.
