Connecting External Buzzers - JRC JMA-5104 Instruction Manual

9.3.14 Connecting external buzzers

This equipment is equipped with dry contact output for external buzzers.
Dry contact is output from a jumper set between pins 6 and 7 from the 8-pin connector of J5. The
contact of the output is a capacity up to 1A/30V.
If a greater current/voltage is applied, install equipment of adequate contact capacity such as
relay in the external section.
If the current/voltage exceeds the contact capacity, the contact of this equipment becomes fused
and the external buzzer keeps ringing, causing an extremely dangerous situation.
