SAFETRON REC is a relay card which manages re-entry in combination with SAFETRON SL621 and SAFETRON SL630 when used with emergency escape hardware 794, or with emergency hardware 793 when the lock is set in split function, provided that the fire alarm is active.

The handle function in SL621 and SL630 has a fail secure function and thus re-entry is activated by breaking the voltage to the door environment. The breakdown can take place through an activated fire alarm or through an activated emergency exit device 793 or 794 connected to the SAFETRON REC.

Re-entry via emergency exit equipment 794

The lock's dørvrideraktivering via SAFETRON REC, and the emergency exit device's micro switch is connected to REC. When the emergency exit fitting is activated, the latching relay switches, which breaks the voltage to låskassen is then put into a mechanically connected position, thereby allowing tilbakerømning. This method provides locally activated tilbakerømning each individual door environment.

Reset is performed by potential-free closure to the relay card. 

Re-entry via dørvrider mandatory fire alarm)

An alternative method is to use the lock's built-in pressure sensor to activate tilbakerømning the event of an activated fire alarm. Re-entry is then activated when a person opens the door using dørvrider inside dørvrider only if the fire alarm is also activated.

Reset is performed by means of a potential-free connection to the relay card.
