SECURITRON PB3, PB3A, PB3N, PB3AN EXIT BUTTON
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The model PB3 is a spring loaded momentary rectangular exit button, with bi-color illumination,
mounted on a stainless steel single gang outlet box cover. The model PB3A is alternate action
(push-on; push off). Adding "N" to the part #(PB3N, PB3AN) yields mounting on a 1 3/4"
narrow stile plate. The NO and NC (DPST) contacts switch when the button is depressed and
return when it is released. The switch is UL listed with 3 AMP capacity. Note that the switch
type is double pole double throw. Two of the contacts are not factory wired (see drawing
below). The reason for this is that all six contacts are rarely required and providing less factory
wiring makes for a less crowded hookup. The installer may use these contacts by soldering
leads to them.
The red and green lamps can be individually operated according to the needs of the installation.
The red lamp is an LED mounted above the button and the green lamp is an LED, illuminating
the button itself. The PB3 can be used for momentary release of fail safe or fail secure electric
locks. If interfaced with a release hold timer, such as Securitron's TimeMate, 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 PB3 comes with a retrofit backbox and color coded hookup wires installed. The backbox
(Securitron PN# 560-10200) includes a template. The drawing below shows the unit's
connection points.

3. LAMP OPERATION
Resistors are installed so that the lamps may be operated on either 12 or 24 VDC. The yellow
wire drives the red LED and the green wire drives the green LED. The yellow wire has a single
resistor soldered in line and the green wire has two resistors soldered in line. If the power
supply is 24 VDC, connect directly to the wires. If the power supply is 12 VDC, remove the
resistor on the yellow wire and the outer resistor on the green wire for proper operation at the
lower voltage.
