Fire Service Overlays
Fire Service Panels
We’re not going to sugar coat it. Fire Service Overlays either install relatively easy or become a nightmare that can last weeks. This directly relates to how good the existing wiring diagrams are and whether or not the controller has been rewired over the years. We’re all obviously trying to save our customers money, and if you’re confident that the wiring diagrams you have are pretty accurate, we can provide a price for your overlay after we've reviewed your wiring diagrams.
Using PLC logic we build a control system with fire service feature so that you can integrate the fire service panel into your non code compliant elevator system. Depending on the type of control, manufacturer, and operating voltage, all fire service panels can be designed and programmed to meet the local code where they are to be installed. Working from the existing controller wiring diagram each new fire service overlay is built for ease of connecting the two. Complete wiring diagrams and cross connection sheets are provided.
In addition to the fire service panels, the car and hall fixtures necessary to make the system operable are available. A standard CJA fire service key switch is used for the car and hall fixtures. However, the customer’s switches can easily be substituted. Fire Fighters instructions, “In Case of Fire....,” etc. can be engraved on the fixtures if requested.
In the process of designing the fire service panel, requirements which may not be in the present control system can be included at little or no additional cost. Of particular note are ADA requirements such as passing buzzers, directional and arrival indicators and chimes. Buzzers, chimes, etc. can also be incorporated into the fire service fixtures. While installing fire service, the contractor can bring his customer’s elevator into ADA compliance.
Controller Replacement Parts
CJA controllers are built with components that are readily available off the shelf. Throughout the years, CJA has improved the design of the controller and simplified the installation by attempting to minimize the number of point to point wiring needed for installations.
If you have an old controller there’s a good chance that you’ll be able to locate replacement relays, contactors and motor controls for your unit. Just make sure that the replacement is rated at the same voltage and amperage rating. For new controllers, 1996-until now, the PCB boards are the units that help decrease your installation time, and are available.
CJA provides free telephone support for all of our controllers whether they were built in 1914 or 2014! Please note that some older PLC’s may be obsolete. While CJA does its best to provide PLC’s that have a long life, manufacturers of these units may decide to discontinue or upgrade.
