In addition to knowing what your alarm’s trouble alert means, you’ll want to know how to fix it. From there, we’ll discuss some of the most frequent issues that arise on this particular alarm panel. Therefore, we’ll begin with a look at how to diagnose any trouble signals stemming from your alarm. Once your alarm starts beeping, you’ll want to know exactly how to proceed in order to fix the issue. In this post, we examine security system troubleshooting for the NX-8 panel. The user interface for diagnosing trouble conditions, however, differs greatly from that of the Concord system. The keypad option that we installed with this system - the “148E” LCD keypad, looks nearly identical. The Interlogix NX-8 panel uses the same exact sensors and contacts as the Concord panel. This week, we apply the same treatment to the NX-8 panel, another one of our most popular alarm systems. In last week’s post, we dove into Diagnosing Security System Trouble Signals on a Concord Panel. This has historically been a major cause of data center outages, usually when the button was mistaken for a door release.ĮPO button vendors include APC by Schneider Electric and STI.Nothing frustrates alarm customers more than having security system issues that create a constant nuisance. #How do i exit the installers code for my ge networx install#However, since the 2011 version of the NEC, it is possible to put a single EPO switch in a nearby room with approval of the code inspector and the fire marshal.ĭata center teams who do install an EPO button should clearly mark the button's presence, and install it under a clear, lift-cover box, preferably with an integrated alarm, to avoid the risk of somebody hitting it accidentally, and causing unintentional downtime. Historically, EPO buttons had to be installed at every exit door. The specific requirements around an EPO button's size, placement and accessibility vary and depend on local jurisdiction. In most jurisdictions, the EPO switch is not automatically mandated in data centers unless the owners and designers want to take advantage of certain options such as loose power whips under air plenum floors or non-plenum cable. Although Article 645 defines the circumstances under which an EPO button is required, the definition is often misinterpreted. In contrast, NFPA 70, more commonly known as the National Electrical Code (NEC), is a mandatory code. Even then, it may be negotiable with the Authority Having Jurisdiction. While NFPA 75 is technically a recommended standard, it is not required by law unless adopted by the local jurisdiction. Three years later the National Fire Protection Association (NFPA) released its first Standard for the Protection of Electronic Computer Systems, which became known later on as NFPA 75. The history of the EPO button dates back to a 1959 fire at The Pentagon that caused over $6 million in damages. The goal of shutting down power in a centralized manner is to limit damage in the event of a disaster and make it safer for rescue personnel deal with the emergency. The button allows all power, including uninterruptable power supplies ( UPSs) and batteries to be shut down safely from a central location.ĮPO buttons can be found in places such as manufacturing plants, telecommunications facilities and information technology (IT) data centers. The Emergency Power Off (EPO) button, also called an EPO switch or EPO panel, is a safety measure for quickly disconnecting electrical power to a particular piece of equipment, or to an entire facility, in the event of an emergency. ![]()
