Cat. No. 855L-NX1

Cat. No. 855L-NX4

These panel light bars are ideal for OEMs and panel builders who want to reduce the quantity of components without the loss of design
reliability or functionality. These devices remove your need for a separate fluorescent lamps purchase. They can be left ON continuously due
to low power consumption and minimum heat generation of modern status indicator technology.

These devices produce a sound output of 108 dB (A) maximum, which is suitable for most mid-range industrial and institutional, single-status
signaling applications. The enhanced version produces sound output of 113 dB (A) max. Our horns have multi-tone and volume control
capabilities. You can retrofit the horns directly into most machine panel cutouts or mount them into traditional 10.2 cm (4 in.) electrical back

Steady LED Module

This product line includes 40 mm (854J) and 60 mm (854K) stack lights.

Bulletin 854J — 40 mm Control Tower Stack Lights

These devices provide reliable, high-performance, high-visibility machine multi-status indication in a cost-effective
package. They feature IP66 enclosure rating and is rated for indoor and outdoor use, which makes them an ideal signaling
solution for a broad range of applications. With a wide variety of mounting bases available, they can be installed in any
orientation — vertical, sideways, or upside-down — to best suit the application. They can be preassembled to save time or
ordered as separate light and sound modules for customized field assembly.

Steady LED Module

Bulletin 854K — 60 mm Control Tower Stack Lights

These devices are designed to communicate application status, alerting you to critical equipment and system needs on the
plant floor. They feature an IP66 enclosure rating and is rated for indoor and outdoor use, which makes them an ideal
signaling solution for a broad range of applications. With a wide variety of mounting bases available, they can be installed in
any orientation — vertical, sideways, or upside-down — to best suit the application. They can be preassembled to save time
or ordered as separate light and sound modules for customized field assembly.

Table 121 - Leakage Current Impact

All light modules, sound modules, and light/sound modules can absorb up to 3 mA of leakage current from solid-state outputs without module activation. Some light and
light modules with sound may not turn off completely when connected to solid-state outputs that emit leakage current. The following modules can be affected by an
output module emitting a maximum of 3 mA. A dry contact can be used to reduce the effect of leakage current.

These devices give you the flexibility to meet the widest range of applications with a reduced number of components. This system uses a
modular design that incorporates brighter LED illumination and a broad offering of sound technologies. All signals in the system are 24V AC/
DC powered, which means that just three power modules can cover the entire system. They can be purchased as separate components or as
a preconfigured, factory-assembled stack light for optimal flexibility.
