The new ST-I Ionisation and ST-P Photoelectric Smoke Detectors form part of a brand new range of
fire detectors from Nittan (UK) LTD called SENSORTEC. The ST-I and ST-P are low cost, elegantly
designed, low profile detectors which are aesthetically pleasing, thus enabling them to blend
unobtrusively into modern working environments. They feature the very latest technological
advancements such as ASIC design, which increases reliability and performance.
The ST-I and ST-P are compatible with other existing conventional fire detection systems.
A new STB range of bases has been introduced to work with the SENSORTEC products, however the
ST-I and ST-P are also compatible with our previous RB-3/6 type base range.
SENSORTEC Conventional Ionisation Smoke Detector
Model: ST-I
The ST-I conventional ionisation detector utilises the dual
chamber, single source principle to provide optimum
response to smoke.
The Radioactive source is only 33.3kBeq., (0.9µ ci), Americium 241, therefore conforming to OECD recommendations. The detector's design provides strong immunity to
air velocities, contamination and RF interference.
Variants:
ST-I-IS c/w STB-4IS Intrinsically Safe version.
ST-I-DA With Service Alarm facility.
SENSORTEC Conventional Photoelectric Smoke Detector
Model: ST-P
The ST-P conventional photoelectric smoke detector
utilises the light scatter sensing principle, the LED pulses
every 8 seconds to maintain a low monitoring current. A
quick charge time, (30 seconds), is also achieved. The
detector incorporates an alarm verification function which
requires two successive pulses before an alarm is given.
(The interval between the first and second pulse is
automatically reduced, to two seconds, after the first alarm
condition is perceived).The detector's design provides
strong immunity to air velocities, contamination and RF
interference.
The ST-P and ST-I have a chemically etched screen and
their sensitivity is also easily confirmed in the field, using
the NID-ET5 electronic tester.
Variants:
ST-P-DA With Service Alarm facility.
ST-P-LV 12V version.
