NKDB TYPE

FEATURES

No serge, no noise

Serge and noise don't generate because circuit opening and closing don't exist.
This alarm can be used near electronic devices which are sensitive for noise.

Dual output of bell and buzzer sounds

Bell sound for major failure and buzzer sound for minor failure can be output together when 2 failure happens simultaneously.

Test circuit is not necessary

Test circuit is not necessary because test switch is built-in the body.

Small size, lightweight

Small and lightweight body is suitable for every place.
