The model PB3 is a momentary exit button that is spring loaded. This is mounted on a stainless steel box cover and comes with bi-color illumination of red and green. These red and green lamps can be individually operated according to the installation needs. Note: adding “N” to the part number has it mounted on a 1 ¾” narrow stile plate.
The red lamp is an LED that is mounted above the button and the green lamp is an LED which illuminates the button itself. The PB3 can be used for the release of fail-safe or fail secure electric locks and if interfaced with a release hold timer, such as TimeMate, it can provide for timed releases of those electric locks. Note: It is recommended that the local building or fire safety authority be consulted prior to using the exit buttons. A “no special knowledge” exit device might be needed.

There are many different models for the PB3, each with its unique differences.
The PB3E is a rectangular exit button without indicators, mounted on a SG key plate. Being the economic version, it comes with a color coded hookup wires installed. It can be used in many different ways but one of the most common applications is the momentary release of a fail-safe or fail secure electric lock and timed release using other devices such as TM-9 TimeMate. The model PB3EA is an alternate action (push-on; push-off). Adding an “N” to it (PB3AN , PB3EN , and PB3N ) has it mounted on a 1 ¾” narrow stile plate. The PB3A is the same as the PB3 except it has an alternate action.

The PB3 has the ability to change from DPST to DPDT when it comes to the field. If you wish for it to be weather proof, there is the WCC and WBB options for the buttons, key switches and keypads. At a size of 4.5” x 2.75” (114mm x 70mm) or 4.5” x 1.75” (114mm x 44mm) depending on the plate, this device can fit in the smallest of places for your convenience.
