As well, it is available with a Pneumatic or Electronic adjustable time delay to meet NFPA and BOCA code requirments. All contacts are UL Recognized components.
When used in conjunction with access control software/hardware, the Pneumatic time delay is the perfect choice of contacts. DC power to the maglock is routed through the set of normally closed contacts to assure unlocking of the maglock when the W5287 Pushbutton is activated. Simultaneously, a separate set of normally open contacts signal the access control system of a request to exit (R-E-X). The lock power and R-E-X signal are kept separate through the double set of contacts.
