Application Scenarios 

In noisy working environments, the built-in ringtone volume of analog telephones is limited, resulting in weak incoming call alerts and missed calls. An external analog sound and light alarm can deliver synchronous audio-visual warnings to strengthen call reminders, improve on-site recognition and ensure timely communication response. 

Usage Method

 The sound and light alarm can be connected in parallel to the analog telephone line. It supports synchronous linkage triggering with analog telephones and can also operate independently. Featuring strong compatibility and sensitive response, it effectively enhances warning performance to meet the demands of various application scenarios.
