These are critical questions, and most of the time, will be met with a puzzled look. Most surge protectors do NOT remove AC power load to a Fire Alarm Control Panel, nor do they trip the circuit breaker when they self-sacrifice. By design, the status indication of most surge devices is via the green LED. If the LED is not inspected on a regular basis there could be a situation where the surge protector has done its job, but is no longer providing surge protection for your life-safety equipment. And let’s be candid, who has the resources available to walk around and check the status of LEDs on a surge protector?
Enter DITEK’s DK-120SRD, with its Dry Contact Remote Notification feature. This surge protective device has the ability to alert the fire alarm system immediately if it is ever compromised. This notification process will work in one of two ways, depending on whether your fire alarm system is Addressable or Conventional. For an addressable system, a dedicated monitoring module can be wired directly into the Form C dry contact circuit of the DK-120SRD, and then configured to alert the fire alarm panel when the contact circuit is switched. On a conventional system, the Form C dry contact circuit can be wired directly into an auxiliary contact input on the FACP itself. There is no guessing! If the DK-120SRD is compromised or self-sacrifices, this “smart surge” design communicates with the fire alarm panel and notification is immediate.
Wouldn’t you want to know immediately if your life-safety equipment is unprotected and your surge protector needs to be replaced? A critical question now answered by DITEK Corporation’s DK-120SRD surge protective device.
