The DS3000 is the new version of the DS2009. The advantages of the DS3000 include a much lower current draw, a more robust roller construction and a more positve action. The unique rollerbolt mechanism and angled strike plate enable the lock to resist up to 1 tonne of side load and yet still release under side pressure making it a genuinely fail safe device exceeding the requirements EN13637. The lock is also much more sympathetic than a standard shearlock to doors which do not align properly and will pull a door in with a misalignment of up to 10mm. We have now had these locks fitted in buildings such as hospitals where double action doors have always been a problem to lock electronically and they have proven to be a success.
