Possibly you have been using mineral insulated (MI) cable to satisfy fire alarm electrical code since you thought there is little else available. That is not true. There’s now a different to MI cables that fully meets the two hour fire resistive circuit integrity requirement of high increases and demanding facilities. Silicone based fire alarm cables are a fantastic option to MI cables. Continue reading for more information concerning the product’s numerous benefits.
Advantage #1: Safety – Silicone fire alarm cable helps to ensure that fire security systems function in extreme environments for lengthy amounts of time. Consequently, it enables here we are at evacuation and provides first responders more response time. It might mean the main difference between saved lives and lost lives, which by itself helps make the product worth the money.
The zinc-coated conduit that lots of high increases rely on can fail in as couple of as twenty minutes. Is that this sufficient time for those occupants to evacuate securely? Maybe when the high-rise is 10 tales or fewer, but unlikely even so. This is because during most practice drills the chaos that ensues throughout an actual emergency can’t be replicated. And too-early failure from the cable might have devastating effects, namely a severing of voice communication with emergency response personnel.
Advantage #2 – No zinc – Silicone fire alarm cable uses silicone as opposed to the known-to-fail material zinc. Cause problems can erode the zinc coating on traditional fire alarm cable within half an hour. Indeed, the existence of even a tiny bit of zinc within the conduit can precipitate this early failure. But, zinc cable can continue to legally be employed in the U . s . States. Non-zinc (e.g., silicone) electrical metallic tubing however consistently demonstrate more than three hrs of survivability. This substantially greater time allowance enables safe evacuation from the tallest high increases.
Advantage #3: Versatility and Easy installation – Silicone fire alarm cable is much more flexible and, being an extension of this, simpler to set up than MI cable. These cables are often pulled with an EMT conduit system that has additionally been certified using the cable to supply the most in fire safety.
Advantage #4: Standard Meeting – Silicone fire alarm cable meets the most recent standards. Underwriters Laboratories (UL) lately issued the UL2196 interim protocol, which mandates that the entire system be certified, such as the make, size and type from the EMT conduit, couplings, clamps, inserts and boxes. More particularly, DuraLife FPLTM was lately the very first cable available to become certified under UL2196, Tests for Fire Resistive Cables, using the recently implemented requirement that posted cables contain five occasions the amount of wires or cables to pass through the fireplace test without failure.
When high end wire or cables like DuraLife FPLTM is known as for, speak to a high end cable and wire expert to go over the benefits that affect your particular situation.
