SECURITRON PB5E EXIT BUTTON
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The model PB5E is a spring loaded momentary 2" diameter, exit button, mounted on a stainless
steel single gang outlet box cover. The DPDT contacts switch when the button is depressed and
return when it is released. The contacts are UL listed with 5 AMP capacity. The PB5E 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
As the PB5E is an economy version, it is supplied without a retro-fit wall mounting device and
without hookup wire. Connection is made via .250" quick connect terminals found on the rear of
the unit. To connect these terminals, the installer may use push on connectors to which wires
are crimped or wires may be directly soldered to the terminals through the hole provided. If a
back box is used, the installer should select a box with minimum depth of 2 1/2". The drawing
below shows identification of the switch's common, normally closed and normally open
terminals. Note, however that an end view of one contact block is shown. The unit has a double
pole, double throw output so there is a second block affixed next to the first with the contacts in
the same orientation.

3. SWITCH ILLUMINATION OPTION
The PB2-LK is a field installable illumination kit intended for the PB2E/PB5E/EEB2 series
pushbuttons which includes the LED, wires and instructions needed to add illumination to the
switch.
4. WIRING
The PB5E can be used in many different ways but the drawings below show three common
applications. The first shows momentary release of a fail safe or fail secure electric lock. The
second drawing shows timed release of a fail safe electric lock using the PB5E and Securitron's
TimeMate. Momentarily pressing the button will release the lock for the amount of time set on
the TimeMate. The wiring is also done in double break fashion so that even if the timer fails, the
button will still be able to momentarily release the lock. This is for added safety. The third
drawing shows interface of the PB5E with an access control system such that a fail safe lock
(generally a magnetic lock) is released for the amount of time programmed into the system in
safe, double break fashion. In this third application, both poles of the PB5E are required. The
NC contacts of the PB5E are connected in series with the NC contacts of the access control
system’s lock control relay and the NO contacts of the PB5E connect to the REX input terminals
of the access control system such that when the button is pressed, the access control system
will operate its relay thereby releasing the lock and allowing egress. But if the access control
