Discontinuation of door sequence selector SR 2000 E
Discontinuation of door sequence selector SR 2000 E – Magnet for electromagnetic hold‐open no longer available
For double‐leaf fire doors, in addition to the “simple” SR 90 with arm, we also supply the SR 2000. Here, only the housing is visible when the door is closed, and no arm, and no stop brackets are required on the door as with the SR 90. Therefore, the SR 2000 is the ideal solution for doors with higher aesthetic standards.
Up to now, the SR 2000 was available with and without hold‐open. In the version with hold‐open, these were held in place in the housing by a small built‐in electromagnet until the magnet was switched off by a smoke detector. Only after this did the arm fold out.
The magnet used for this purpose used to be manufactured by WaCo in large quantities, as it was also used by Dorma for door closers. This is no longer the case and manufacturing these special magnets in such small quantities as the SR 2000 E is sold in recent years is no longer cost‐effective.
Therefore we have to stop the production of the door sequence selector SR 2000 E with electromagnetic hold‐open.
This affects the following article numbers:
500431 SR 2000 EL door sequence selector, length 1050 mm (with electromagnetic locking device), LE 02003
500436 SR 2000 EK door sequence selector, length 650 mm (with electromagnetic locking device), LE 02002
The SR 2000 is still available without the electromagnetic hold‐open: Art. nos. 500430 and 500435.
