WPS-08. Weatherproof Call Station, 4 Double Toggles

WPS-08. Weatherproof Call Station, 4 Double Toggles

The weatherproof call station WPS-08 with four-wire technology is designed for use in harsh environments. The housing is resistant to many chemicals and can be used in a range of temperatures from -30 °C to +70 °C.

At a Glance:

  • 4 toggles (8-way) with LED
  • Comes standard with built-in 25 Watt booster amplifier
  • Weatherproof design (protection rating IP65)
  • Large temperature range (-30 °C to +70 °C)
  • Resistant to many chemicals
  • Flame resistant
  • Easy installation

The WPS-04 consists of:

  • The mechanical components:
    • Housing base made of glass fibre reinforced polyester in orange (RAL 2004)
    • Housing cover, also made of glass fibre reinforced polyester in orange with recessed control panel also made of glass fibre reinforced black polyamide
    • Double toggles made of glass fibre reinforced grey polyamide
    • Microphone box made of grey PVC for the dynamic sound capsule (mounted in the cover)
    • Cable connections made of grey polyamide
  • The electrical components:
    • Dynamic sound converter (mounted in microphone box)
    • 4 W/6 W loudspeaker (mounted in the cover)
    • Motherboard with 4 W call station amplifier including 25 W booster amplifier (mounted in housing base)
    • Keypad circuit board (mounted in the cover)

Cover and housing base are connected electrically through a plug-in ribbon cable.

The WPS-08 is connected to the DVS-21 through the analogue LF interface module 4NSA.

Voice transmission between the call station and the DVS-21 is analogue. Control and data transmission is handled digitally by a microcontroller. Transmission is carried out with a modem connection.

Busy signals, voice acknowledgments and call signals are indicated by the LEDs. The display and blink behaviour of the LEDs can be programmed with the system software ICS of the DVS-21.

The WPS-08 can be expanded with up to three AWC-06 add-on toggle sections (6 toggles).

Additionally, external 100 V loudspeakers (optional also 50 V or 70 V) up to a max. of 25 Watt can be connected.
