Specialist Detectors
In addition to standard detectors, Apollo offer a range of
specialist detectors suitable for a wide variety of
applications.
Beam Detectors offer a cost effective solution for
protecting large open spaces. One single unit installed on a
wall can detect smoke over an area up to 1500m2 (BS5832),
which is beyond that of traditional point detectors. Beams
are therefore ideal for protecting areas such as
warehouses, theatres and sports centres.
Types of Beam Detector:
• Self-Aligning:
comprises a combined transmitter/receiver which is operated
through a low-level, easy-access control console. As the name
suggests the detector compensates for building movement.
• Reflective: the
combined transmitter/receiver projects a beam to a prism
mounted on an opposite wall.
• End-to-End:
consists of a separate transmitter, receiver and
interface.
Flame detectors are effective in protecting areas
where flaming fires may be expected. There is a choice of
detection techniques - ultraviolet (UV), infra-red (IR) or a
combination of both:
• IR2: High immunity
to false sources (indoor areas)
• IR3: Excellent
immunity to false sources (indoor or outdoor areas)
• UV/IR2:
Highest immunity to false sources (indoor or outdoor
areas)
UV flame detectors are generally used in engine
rooms, factories and warehouse applications. IR flame
detectors are able to tolerate dirtier environments which may
block UV radiation and are generally used in applications such
as waste handling, colour printing and paper
manufacturing. Apollo's range of flame detectors comply with
EN54-10.
Duct
detectors are designed for detecting smoke in the
air moving through heating and ventilation (HVAC) ducts
in commercial and industrial applications. They comprise
a purpose-built housing complete with integral tubing, which
samples the fast-moving air so that the detector can operate
in the normal way.
