INTRODUCTION
The Model T110 Test Source from
Siemens Building Technologies, Inc., is
designed specifically for on-site testing
of the S121 and S122 Flame Detectors.
When the plate with the guide is attached,
the T110 is self-aligning and checks
both the sensitivity and response time of
the detectors. The Test Source consists
of a module in a cradle. The module can
be held by hand up to the detector to be
tested or can be fastened to the end of
an extendable pole with an adapter and
then held up against the detector.
This Test Source is approved by
BASEEFA for use in all zone 1 and
zone 2 areas with gases rated T1 and
T4. Approval for zone 0 areas is not
available for this equipment; however,
permission for such use may be
obtained on a site-by-site basis.
The Test Source has a polycarbonate
housing approved for increased safety.
It contains a lamp that is electrically
pulsed by an intrinsically safe circuit.
Infrared energy from the lamp is
focused on the detector through a
Fresnel lens. The unit is powered by
either a carbon zinc or nickel cadmium
battery.
The large rotary switch knob on the
front of the unit (See Figure 1) is used
to turn the Test Source on and off. The
knob is also used to select the correct
sensitivity level for testing either S121
(Sxx1) or S122 (Sxx2).
The extendable pole that can be used
with the Test Source comes in 4 foot, 4
inch sections that slot into each other
and are connected to the Tl10 with the
Extendable Pole Adapter (See Figure
2). The maximum recommended length
of the pole is three sections (approxi-
mately 13 feet).
