Drawing indicated connecting locks must be
“Fail-safe” version. Please connect negative
wire of the lock to N.O. contact if applying
“Fail-secure” locks to avoid damage.
NoteĈ
1. Recommend to apply single voltage power supply unit and beware of AC or DC version of the
connecting locks.
2. It is suggested to use # 22~26 AWG insulation wire.
3. Exit button is at N.O. contact.
4. With CE qualification EMC specification.
5. The door locks or relay must have a varistor or a diode across the door locks terminals to sup press the
back EMF of the locks-failure to do so will damage the relay contacts and electronic components , or
even burns the controller.
