Securitron's Touch Sense Bar
Unique Touch Sensitive Exit Bar For Use With Magnetic Locks
On magnetically locked, non fire-rated doors, most building
codes require an exit device that does not require any special
tools or knowledge. Securitron's patented Touch Sense Bar is
the perfect device for this requirement. The simple act of
touching the bar (even through gloves or clothing) trips an
electronic sensor which immediately releases the lock.
The Touch Sense Bar is the ultimate in egress reliability and
safety. Having no moving parts, it does not suffer mechanical
wear and no pressure is required for use which provides superior
egress safety for frail or disabled persons.
Easy Installation On Any Door
The TSB-3 comes complete with fastener sets allowing quick and
strong installation on metal, aluminum-framed glass or wood
doors of all types. A stainless steel door cord is also
supplied to route wiring (16 ft. cable supplied) from bar to the
door frame. With a hoolow door frame, the wiring can be
concealed or it can be surface run in pipe if the door frame is
filled. The Touch Sense Bar is offered in three standard dooor
opening widths (36", 42" and 48"). For a non-standard opening
width, the unit can be easily cut down in the field.
Meets "No Tools or Knowledge" Code Requirement
Integration With Access Control
Many applications call for controlled entry from the outside of
the door and free egress from the inside. Use of the Touch Bar
as the egress device makes this simple, safe and reliable, The
TSB has a double pole relay output. The NC contacts are wired
to directly break power to the magnetic lock when the bar is
touched. The NO contacts connect to the REX (request to exit)
terminals in the access system controller so that no alarm event
is created during free egress. Extra safety is achieved because
in the event of a failure in the access control system, the
Touch Bar will still directly release the lock.
While the Touch Bar features no-moving-parts electronic
reliability, it goes beyond by providing a second independent
release circuit. A push button provides backup lock release
function in the event of any sensor failure. This fits into the
modern safety engineering concept of eliminating the possibility
of funtional failure if any single device fails. It's another
example of the careful thought and concern for user safety that
has gone into the design of the Touch Sense Bar.
UL Listed Systems
Where egress safety is at issue, it helps to know that
Securitron egress systems built around the Touch Sense Bar have
been tested and listed by Underwriter's Laboratories. The first
system is called "XP-1".
This consists of a Touch Bar and any 32 or 62 series Magnalock,
with both being operated by a Securitron BPS series power
supply. This system is listed by UL as a releasing device. It
provides immediate free egress on any door and is generally
integrated with controlled entry means such as a card reader or
The second system is called "EXD-1" and this provides delayed
exit under NFPA-101.
In addition, the TSB-3 Series is a UL Recognized stand alone
component for use with any electromagnetic lock. This makes the
TSB-3 series the perfect retrofit solution for existing
electromagnetic lock installations, no matter what brand lock it
