Cistermiser Direct Flush Valve - Infrared Urinal Flush Control Valves

Cistermiser Direct Flush Valve - Infrared Urinal Control Valves

Cistermiser Direct Flush is an infrared sensor controlled urinal valve.

The Direct Flush automatically flushes the individual urinal after use, ensuring the highest level of hygiene from the minimum volume of water supplied directly from the mains.

Cistermiser Direct Flush removes the need for the auto-flush cistern and associated plumbing used in traditional urinal installations which flush all urinals intermittently even if they have not all been used.

How It Works

The Cistermiser direct flush infrared sensor detects the user at the urinal bowl and flushes 2 seconds after the user departs.

If a user is detected whilst flushing, the flush is automatically arrested to prevent splashing and wastage.

The flush duration is adjustable which ensures that only the minimum amount of water necessary is used.

If there has been no flush in the urinal for 12 hours, the direct flush automatically runs a hygiene flush.

  • Direct Flush includes an integral DC pipe interrupter (air gap) enabling the installer to connect it directly to the mains water supply. This provides fluid category 5 back-siphonage protection, without the need for any additional backflow prevention or check valves.
  • Direct Flush can be powered by either mains electricity via the DC transformer or batteries: both options are included as standard. When batteries are fitted the Direct Flush provides a low battery warning indicator.
  • A mains power supply unit (PSUC) which powers up to 20 direct flush urinal valves is also available. Only 1 fused spur is required when using this product.
  • Additional customised washroom settings are obtainable via a hand held remote control Infrared Configuration Unit (ICU) which is available as an optional extra. The remote controller enables rapid automatic range configuration to the specific washroom dimensions, deactivation of the hygiene flush function and where a siphonic trap has been fitted, activation of the trap refill function.
