4. PRINCIPLE OF OPERATION
Following an impulse from the electronic access control module, the servomotor unlocks
mechanical transmission, thus enabling door opening via normal pressing of the door han-
dle on the external door handle set. Opening is signalled via sound and LED being switched
on. The waiting time for handle pressing is set by the factory for a period of approximately 5
seconds, then the transmission is locked again and the lock awaiting another impulse from
the electronic access control module.
It is always possible to open the door via normal pressing of the door handle from the inter-
nal side (of the room). After the door is closed, the pawl mechanism activates immediately,
disabling opening of the door from the outside without the impulse from the electronic ac-
cess control module.
There is a possibility for emergency lock opening using a normal mechanical key, 2 pieces of
which are provided with each door handle set with access control (item 5.4).
5. INSTALLATION OF LOCK IN DOOR
The ELH-62B9/ ELH-72B9/ ELH-82B9 sets include an arbor enabling installation of door
handle sets in doors with 30~50 mm thickness.
Warning!
In the case of using ELW-06B9 spacers in doors with thickness in excess of 40 mm one
should remember to replace the arbor with a longer unit (approx. 70~80 mm*).
The spacer has identical openings as the one to be performed in the door wing.
In order to increase security, it is recommended that ELH-62B9/ ELH-72B9/ ELH-82B9
control door handle sets are installed in rebated doors.
Warning!
Installation shall be performed with emergency keys at hand, as they might prove indi-
spensable in the case of doors with non-programmed lock being slammed shut.
* Additional arbor not included.
