SECURITRON PB, PBA EXIT BUTTON
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The model PB is a spring loaded momentary, 1 1/2" Diameter, exit button, with bi-color
illumination, mounted on a stainless steel single gang outlet box cover. The model PBA is
alternate action (push-on; push off). The NO and NC (DPST) contacts switch when the button is
depressed and return when it is released. The contacts are UL listed with 7 AMP capacity. The
indicator LED and the switch LED can be individually operated according to the needs of the
installation. The indicator LED is mounted above the button and the switch LED illuminates the
button itself. The PB can be used for momentary release of fail safe or fail secure electric locks.
If interfaced with a release hold timer, it can provide for timed release of electric locks. It may
also be used to input a REX (request to exit) signal to a card reader system. We recommend
that the local building or fire safety authority be consulted prior to using exit buttons for door
egress. They may require a "no special knowledge" exit device such as Securitron's Touch
Sense Bar.
2. INSTALLATION
The PB comes with a retrofit mounting device and color coded hookup wires installed. The
drawing below shows identification of the unit's connection points.

3. LAMP OPERATION
Resistors are installed so that the LEDs may be operated on either 12 or 24 VDC. The yellow
wire drives the indicator LED and the green wire drives the switch LED. Both wires have a single
resistor soldered on them. If the power supply is 24 VDC, connect directly to the wires. If the
power supply is 12 VDC, remove the resistor for proper operation at the lower voltage.
The switch LED draws 30 mA and the indicator LED draws 20 mA at either voltage. For
replacement LEDs see chart below:
4. WIRING
The PB can be used in many different ways but the drawings below show two common
applications. The first shows momentary release of a fail safe or fail secure electric lock. The PB
indicators are connected so that the switch button illuminator is normally on. When the button
is pressed, releasing the lock, the switch LED turns off and the indicator LED comes on. The
second drawing shows timed release of a fail safe electric lock using the PB and Securitron's
