Multi-Tone Open-Area Alarm Devices
function
The Multi-tone Open-Area Alarm Devices are designed
for use in open areas and can be connected to any XP95®
or Discovery® system.
The range comprises sounders and sounder beacons.
Details are shown in Table 1 overleaf.
Note: These are not compatible with systems using
Discovery sounders
Features
The Alarm Devices complement Apollo’s Integrated Base
Sounders and Sounder Beacon Bases.
The Alarm Devices offers:
• two volume settings 92dB(A) and 100dB(A)
• synchronisation of ‘alert’ and ‘evacuate’ tones
• individual & group addressing
• available with or without built-in isolator
• weatherproof version available
• red or white options
• three tones on standard devices; Apollo, slow
whoop and DIN – all of which comply with
EN54–3:2001
Synchronisation of the tones ensures the integrity of the
signal – tones from different sounders do not merge into
one signal that could be mistaken for a different tone.

Multi-tone Open-Area Sounder Beacons
A nominal sound output of 100dB(A) is achieved at a
current consumption of 5mA in the case of the sounder
and 9mA for the sounder beacon. Many control panels
will be able to drive up to 20 sounders per loop on
average. The maximum number of sounders that may
be connected to a particular loop should, however, be
determined by a loop loading calculation using the Apollo
Loop Calculator. This is available via the Apollo website
www.apollo-fire.co.uk/loop-calc
Since the Multi-tone Open-Area Alarm Devices are
intended for use in open areas, it is possible for more than
one sounder to be audible at any given point in a building.
For this reason, the operation of all the sounders may be
synchronised by sending address ‘0’ in exactly the same
way as for the XP95 Sounder Control Unit. Not only that,
the Multi-tone Open-Area Alarm Devices can be assigned
group addresses as well as individual addresses, so that
the functional options of the sounder are identical with
those of the Sounder Control Unit.

group address may be any spare address between
112 and 126 and is selected by means of a 4 segment
DIL switch. An Alarm Device under group address
control must have an individual address between 1 and
111 otherwise a fault value of 4 is transmitted. Alarm
Devices not using the group address facility may be
addressed at any address (1–126).
SyNchronisation
The Multi-tone Open-Area Alarm Devices can be
synchronised with other sounders by using address
‘0’. It is recommended that address ‘0’ be sent at ten
minute intervals by the control panel.
NB: Units on two or more loops can be synchronised
in pulsed mode only if the panel transmits address
’0’ to all loops synchronously, with the output bits
set to ‘0’.
protocol compatibility
The devices will operate only with control equipment
using the Apollo XP95 or Discovery protocol. The
features of the Multi-tone Open-rea Alarm Devices
are available only when the sounder is connected to
a control panel with the appropriate software.
protocol bit usage
The output (or forward command) bits from the
control panel have the following function:
The interrupt bit is always set to ‘0’, logic low.
The analogue value bits are set to report a pre-set
analogue value of 16 in quiescent condition.
The input bits confirm the execution of the commands
given by the output bits:
Bit 2 is set to logic ‘1’ for group addressing and to logic ‘0’ if individual addressing has been
applied.
Bit 1 is set to logic ‘0’ when the sounder is not
operated and to logic ‘1’ to indicate that the
sounder has been switched to operate in pulsed
mode, one second off, one second on.
Bit 0 is set to logic ‘0’ when the sounder is not
operated and to logic ‘1’ when it is operated
continuously. If both bits 1 and 0 are set high, this
also indicates that the sounder is in continuous
mode.
The Multi-tone Open-Area Alarm Devices transmit seven
bits to confirm its address and then places one bit to
indicate that the device is using the XP95 protocol (XP95
flag).
The alarm flag is not placed by the Alarm Devices.
Output bit 2 is used to apply the required address
mode — group addressing or individual addressing.
The following five bits, extension of the analogue value,
are not used by the Alarm Devices
electrical considerations
The Multi-tone Open-Area Alarm Devices are
powered directly from the loop and need no external
power supply. They operate at 18–28V DC and are
polarity sensitive.
Group addressing is selected by setting output bit 2
of the individual address to logic 0 on two or more
consecutive cycles and output bit 2 of the group
address to logic 1 on two or more consecutive pollings.
All other output bit 2 combinations result in the
application of the individual address mode.
The parity bit is set to ‘0’ or ‘1’ in the same way as it is
by XP95 detectors.
TONE FREQUENCY AND VOLUME CONTROL
The Multi-tone Open-Area Alarm Devices have three
selectable tones either — Apollo, Slow Whoop or DIN
(see Table 2).
Whichever address mode — individual or group — is
applied in any polling, the use of the other output
bits is identical:
Table 1 Multi-tone Open-Area Alarm Devices
The volume control can be used to adjust the sound
from 100dB(A) to 92dB ±3dB(A) if required.
The sounder also offers synchronisation of continuous
and pulsed tones. This ensures the integrity of the
alert signals – tones from different sounders do not
merge into one signal that could be mistaken for an
‘evacuate’ tone.
Addressing
The Multi-tone Open-Area Alarm Devices responds
to their own individual address set with a DIL switch.
They can also respond to a ‘Group Address’ which allows
multiple sounders to be controlled simultaneously. A
The seven bits which are then transmitted by the
control panel correspond to the individual or the
group address (as set on the relevant DIL switch) of
the device or devices to be polled. These bits may
also be set to zero to enable the unit to respond to
the embedded address ’0’.
After the Multi-tone Open-Area Alarm Devices have
been addressed by the control equipment, return
data if (and only if) its individual address has been
applied. No data is returned when the group address
is polled. The response after individual addressing
will, however, reflect whatever commands have been
set, whether by individual or by group address mode.
The response is as follows:
Mechanical construction
The Multi-tone Open-Area Alarm Devices are fitted to the
mounting surface with four screws. The weatherproof
versions have an additional square backbox and there
are three drill centre points for cable entry marked on
the upper and lower face.
