The lifespan of intercom equipment is set at 15 years as recommended by the Intercom Industry Association. Intercoms that have exceeded their lifespan not only become unable to facilitate calls or unlock automatic doors, but there is also a risk that various fire safety devices may not function correctly, potentially threatening the safety of customers' lives. Additionally, the availability of replacement parts from each intercom manufacturer is limited to 7 years after production has ceased. Once the parts stocked by the manufacturer are depleted, it will no longer be possible to address issues through part replacements. We encourage you to consider renewing your intercom before its lifespan is exceeded and to reach out to us. *For more details, please refer to the related links.
