CONTROL PANEL
COMPATIBILITY
Discovery detectors are
designed to be operated with
purpose-designed control
and indicating equipment
that makes full use of their
features. Discovery can,
however, be connected to
any control panel which can
operate existing ranges of
Apollo analogue addressable
detectors with the previously
noted rule, that the control
and indicating equipment
must not have a drift
algorithm operating on
Discovery devices. Contact
the panel manufacturer for
guidance. For a list of
compatible panel
manufacturers, see Apollo
publication PP1010.
INTERFACES
All XP95 interfaces are fully
compatible with Discovery
detectors and call points.
Please see the Interfaces
Brochure, PP2025, for
further information.
SOUNDERS
Loop sounders developed
for use with XP95 systems
may be used in exactly the
same way with Discovery.
See publication PP2031.
MAINTENANCE
OF DETECTORS
Apollo Fire Detectors has
published a guide to the
care, maintenance and
servicing of Apollo
products, PP2055, which
is available on request.
This guide outlines the
maintenance routines
recommended for optimum
detector performance and
the services available from
Apollo’s factory-based
Service Department.
ISOLATORS
All XP95 isolators and isolating bases are patented and are
suitable for use with Discovery detectors and manual call points.

MECHANICAL
CONSTRUCTION
All detectors in the
Discovery range have the
same external dimensions,
except the multisensor
detector, which is deeper.
The housing of the
ionisation and optical
smoke detectors is identical.
The material used to mould
the housings is a UL 94 V
–
0
grade of polycarbonate in a
pure white finish.
Two light-emitting diodes
(LEDs) are mounted on the
printed circuit board within
the housing. They protrude
through the lid to be easily
visible and provide external
alarm indication.
The LEDs of the ionisation
smoke detector and the heat
detector are red, and the
optical and multisensor
detectors have colourless
LEDs which emit red light in
the alarm state.
All detectors in the
Discovery range have four
nickel-plated stainless steel
wipers at the back of the
housing which make
contact with the double
terminals when the detector
is fitted to a base.
INTER-
CHANGEABILITY
Any Discovery detector may
be replaced by any other
type in the range. For
example, if a smoke
detector proved unsuitable
in a particular application, it
could be simply replaced
with a heat detector set to
the appropriate grade or
range, provided that the
maximum floor area
coverage does not exceed
that specified by BS5839:
Part1 or other local code.
Discovery detectors can
also be used to replace
XP95 detectors and again, it
is possible to change types,
e.g. smoke for heat or vice
versa when mixing types.
Factory-new Discovery
detectors are set to mid
range, equivalent to XP95,
and the flashing LED feature
is disabled.
Note: the control and
indicating equipment must
not have a drift compensation
algorithm activated when
interrogating Discovery
detectors.
Some XP95 panels may not
recognise the multisensor or
CO detector type codes.
Contact the panel
manufacturer for advice.
