How do I check the age of the alarm panels installed at a security company’s customers?

Start with the customer database. A well-run alarm company records the panel type, installation date, sensors and last visit for each site. If that information is incomplete, say so in your notes, because it tells you something about how the business is run. Group the customers by panel age and see how much of the base sits in older equipment.

Then check for support. Are parts still available? Does the monitoring system still communicate properly with the older panels? Ask the technicians which sites cause the most service calls. Their answers will point you toward trouble faster than any report.

Finally, plan for upgrades. Ask how the owner has handled replacement so far, whether customers pay for it and how they responded. Visit a few sites yourself, with the seller’s permission, so you can see the equipment and meet the customers. Your accountant can then help you judge how replacement costs affect future margins. Pay attention to the communication path, too. A panel that still works may rely on a connection that is being phased out, and replacing the link is one more cost that may land on the new owner.

Key takeaways

• Get panel type, install date and service history for every site.
• Group customers by panel age and ask technicians where problems cluster.
• Ask how upgrades were handled and how customers responded.
• Ask whether the way panels reach the monitoring centre is still supported.
