Alarm Relays & More

Occasionally, you may need to replace or upgrade an alarm part in order for your system to perform at its optimal best. With this in mind, we offer a variety of items from alarm relays, which operate the circuitry that signals your alarm, to filters, timers and more. As with all of our security systems and accessories, each of these items also includes detailed instruction manuals to help your upgrade or replacement go as smoothly as possible.

Thinking beyond replacement parts, some of the items in this section are particularly useful for home automation, which is rising in popularity for the convenience that it offers, as well as the increased security that can be automated, as well. Items like doorbell and telephone ring detectors are also useful for hearing-impaired individuals or those who live and work in high noise environments. Some products also have very practical applications for business like devices used to help create telephone-based paging systems which are useful for businesses with a lot of employees.

If simply looking to better protect your security system and the technology that it interacts with, consider starting with a telephone and low voltage surge suppressor, which can be used with your existing telephone jack or perhaps even a filter for your home alarm system. You may even want to consider a low battery cutoff and master power switch to prevent the deep discharging of your system’s battery in the event of a prolonged power outage.

Our offering of relays and more are useful for home and business structures, and our tech support team is always available to help troubleshoot issues beyond what is included in each manual’s instructions.
