Door communication Audio ctrl.dev. DRA [128700] Audio control device Gira system devices DRA Features: - Control device to supply power to the audio components of the Gira door communication bus. - Power supply of the reverse-polarity protected and short-circuit-proof 2-wire bus. - Self-resetting electronic short-circuit and overload recognition of the operating voltage and the bus connection. - Buttons for system and door opener programming. - LED status indicators for operation, overload, system programming, and door opener programming. - AC 12 V output to supply power to a common door opener. - Permanent AC 12 V output to supply power to a DCS-TC gateway. - Relay output for switching a door opener with its own power supply. - Door opener time continuously adjustable from 1 to 10 seconds. Technical data: Rated voltage - Primary: AC 230 V, 50 Hz - Secondary: SELV 26 DC V ± 2 V Secondary rated current - Continuous load: 160 mA - Peak load: 550 mA (max. 5 s) - Overload deactivation: from 350 mA Connections: 0.6 mm to 2.5 mm² Door opener output: AC 12 V, max. 1.6 A / 25 % switch-on duration Relay output: AC/DC 30 V, 2 A Total cable length: max. 700 m Cable length from control device to most distant device - for cable diameter 0.8 mm: max. 300 m - for cable diameter 0.6 mm: max. 170 m Ambient temperature: -5 °C to +45 °C Notes: - The audio control device is intended to be installed in the sub-distribution. If this is not possible, use a common surface-mounted distributor. - This component enables door communication systems with up to 70 devices to be established (e.g. 1 x built-in loudspeaker, 5 x add-on modules for built-in loudspeakers, 68 x surface-mounted home stations). Dimensions: Modular widths (MW): 6 Make: Gira Order No. 1287 00 DRA Quantity: 0 Stk Individual price: 163.13 £ (without VAT) xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
