The A9054T addressable input/output module is used with Sanjiang addressable fire alarm control panels (EN54 series). Each module provides 4 independent inputs and 4 independent relay outputs, and occupies 4 consecutive addresses on the loop.
Applications
- Control of fire-protection interlocked devices: smoke extraction dampers, pressurization air supply dampers, fire dampers…
- Receives feedback signals from these devices to determine their operating status.
- Each input can be configured at the control panel as a status input or an alarm input.
Features
- Complies with EN 54-17 (short-circuit isolators) and EN 54-18 (input/output devices).
- Built-in short-circuit isolator on the loop.
- Electronic coding; addresses are written on site with a coding tool.
- Two-wire loop connection, snap-in mounting, transparent cover for easy viewing of the indicators.
