As a precious commodity, water needs to be conserved as a vital resource for the future as well as for current use. The Water Byelaws highlight the need to prevent water wastage, unnecessary consumption of water, contamination of water and general misuse of water. Pegler, in recognising these requirements have now developed their Optiflush urinal flush controller for mains or battery operation which they claim can actually cut water usage by up to 80% assisting in minimising fuel costs. Optiflush uses the latest passive infra-red sensing technology which provides accurate control over the amount of water used. A detector senses movement in the cloakroom and activates the valve to flush the urinal after a pre-set time delay. (During the delay period, subsequent users not being detected). At the end of the delay the unit activates the flush. Once the flushing operation is complete, Optiflush closes the valve, re-sets itself and waits for the next user to trigger the cycle again. Maximum hygiene standards are thus maintained whilst minimising water usage particularly during lax periods of evenings and weekends. Optiflush has incorporated a hygiene flush which automatically operates every 12 hours if the cloakroom has not been used during this time. Operating in compliance with byelaws 82 and 83 which are concerned with amount of water used per hour in the flushing process, and with the BS6700 requirement of allowing no more than 3 flushes per hour, Optiflush has been designed to give the maximum amount of flexibility during set up. This allows the time interval between flushes and the length of flush to be varied to meet each installation's specific needs. Pegler's Optiflush is easy to install. The product is located to always sense movement in the room. During set up only an audible test mode setting allows the installer to hear if the product is sited correctly by sensing movement on approaching it from different directions. Regulations dictate a qualified electrician should install the mains Optiflush version which does result in a higher initial cost but thereafter no further maintenance is required. With the battery version maintenance is minimised - the unit is fitted with standard PP3 alkaline batteries (with an anticipated battery life of around 2 years) and has a warning signal to indicate when the battery is low similar to that of a smoke detector alarm unit. |
