Door Bell Interface Principle
Relay contact in BELL _ A & _ B will be close for 200mS then release for each bell stroke . BELL
Alarm Interface Principle
FET (field effect transistor) will be connected when alarm operates, and vise verse.
Lock Interface Principle
Relay will be picked up once unlocking instruction received
,
and it will be released when unlocking
time is beyond .
COM : Relay Contact
NC : Normal Close , which is connected with COM normally .
NO : Normal Open , which is disconnected with COM normally .
Connecting COM and GND
,
then connecting lock to
+

(
or NC
)
Lock Type A : Fail Secure Lock (Unlock when power on ) , such as Electric Controlling
Lock , etc .
Lock Type B : Fail Safe Lock , such as EM Lock , Electric Bolt
Lock , etc .
IN4004 : Diode , which is mainly used for preventing the harmness on relay from surge
high voltage of Lock when relay contact is released. The use life of relay will
be shortened and the high voltage pulse will affect other circuit
(Unlock when power off )
