The Edwards Triliptical Stackable Status Indicator is a unique audible-visual signaling device that can contain up to 5 light modules and a pulsating horn in a single ?stack.? All modules are gasketed.The Triliptical Stackable Status Indicator bases are available in three models. A shorter base for conduit or surface mounting or a larger base designed for use with an optional tone module assembly. The larger base is also available with an optional DeviceNet interface.The Triliptical diffusion optic lens allows viewing from close up while still projecting the light through use of a built-in projection ring.The lenses are available in six colors: red, amber/orange, yellow, blue, green, and clear. Each light source module contains a removable cover to allow for easy relamping. The light module cover features a molded-in gasket for dust tight reliability. Double optics and the triliptical design provides an increased viewing area without increasing the base diameter. The lens modules can be easily stacked together utilizing an internal retaining assembly. Two tone modules are available. A single tone module and a tone selectable tone module - one tone selectable from eight available tones. Provides up to 85 dB at 5 feet. The multi-tone module is also available with an optional DeviceNet interface that allows all eight tones to be controlled over a DeviceNet network.Surface or 3/4" (19mm) NPT conduit pipe mounting in non-hazardous dust and weatherproof applications. For indoor applications, may be vertically mounted with lenses facing up or down. For weatherproof installation, it is recommended that the unit be conduit mounted vertically with lenses facing up.DeviceNet Compatible Stackable Status IndicatorThe 102 Series Triliptical Stackable Status Indicator has been tested by ODVA's authorized independent test lab and complies with ODVA conformance test software.The Triliptical DeviceNet Stackable Beacon is a slave device. It is a general purpose status indicator designed to indicate the status of a machine or process. The unit contains a preprogrammed microcontroller which implements the Group 2 predefined Master/Slave Connection Set. This allows for one Explicit Messaging Connection and one Poll Connection. The Stackable Beacon resets automatically when DeviceNet power is applied.The DeviceNet interface is in the Triliptical DeviceNet Base, 102TBS-DN, which interfaces between the DeviceNet network and all installed stacklight modules. The unisolated physical layer contains DeviceNet required mis-wiring protection circuitry. A standard open style (unsealed) 5 pin connector is used to connect the Stackable Beacon to the DeviceNet bus. The current draw from the bus is 0.12A. The power required to drive the lamps is supplied separately from the bus power for the 120V AC (N5) version. DC power for the 24V DC (G1) version may be taken locally or from the DeviceNet Network. A standard open style 2 pin connector is used to connect 24V DC @ 1.6A or 120V AC at 0.6A to drive the 5 light sources.The DeviceNet compatible unit provides for complete light source diagnostics. Each light source: LED, strobe, halogen or incandescent is continuously monitored for operability. An inoperable or missing light source is reported on the DeviceNet network.
