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 re spond to the embedded
address'0'.
After the integrated base sounder has been
addressed by the control equipment, it returns
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, refl ect
whatever commands have been set, whether
by individual or by group ad dress mode. The
response is as follows:
The interrupt bit is always set to '0'.
The analogue value bits are set to report a
pre-set an a logue value of 16 in quiescent con-
dition and 4 if the group address is incorrectly
set. A value of 1 is reported if the sounder fails
to emit a sound after being switched on.
The input bits confi rm the execution of the
com mands given by the output bits as follows:
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 'alert' mode.
Bit 0 is set to logic '0' when the sounder
is not operated and to logic '1' when it is
operated in 'evacuate' mode. If both bits 1
and 0 are set to '1', this also indicates that
the sounder is in 'evacuate' mode.
The type bits are used to identify the type
of unit re spond ing. The type code of the
Integrated base sounder is 001 00 (bits 2, 1,
0, 4, 3). Bits 2, 1 and 0 of the type code are
sent immediately after the input bits. The
re main ing two bits are sent in the XP95 proto-
col extension.
The integrated base sounder transmits seven
bits to confi rm its address and then places one
bit to indicate that the device is using the XP95
protocol
The alarm fl ag is not placed by the sounder.
The next two bits sent are the extended type
code bits (bits 4, 3) which, in this case, are '00'.
The following fi ve bits, extension of the ana-
logue value, are not used by the integrated
base sounder.
The parity bit is set to '0' or '1' in the same way
as it is by XP95 detectors.
The fi nal seven bits, alarm/interrupt address,
are not used, since the sounder has no alarm
re port ing function.
SYNCHRONISATION
Sounders are able to recognise address 0
and synchronise, as in the case of the 100dB
sounder, the Intelligent Base Sounder and
the Sounder Control Unit. This method of
synchronisation depends on the design and
confi guration of the control panel. The manu-
facturer of the panel should be consulted to
determine whether this feature is available or
not.
TYPE CODE
The sounder type code is 001 00. (bits 210 43).
MECHANICAL CONSTRUCTION
The integrated base sounder is moulded in
polycarbonate and has stainless steel contacts
that accept solid or stranded cables of up to
2.5mm².
