EN54-23 Open Class—FC430LPBSB LP Loop
Powered Beacon-Sounder Base
Introduction
The EN54-23 Open Class—FC430LPBSB LP Loop Pow-
ered Beacon-Sounder Base is designed to be driven
from a FIRECLASS controller via the addressable loop.
The FC430LPBSB LP is designed to be fitted between
a detector and a 4" mounting flange.
A ‘Type A’ mounting flange is supplied with the base
and can be fixed to a flat surface or a suitable electrical
backbox with standard 50 mm, or 70 mm fixing centres.
Alternatively, a DAB3-4 mounting flange (to be ordered
separately, refer to “Order Information” on page 14)
can be used with surface mount trunking.
Fig. 1 shows a general view of the base.
The beacon-sounder base may be used without a detec-
tor by fitting a blanking cap (see “Order Information” on
page 14).
The detector or blanking cap must be locked onto the
beacon-sounder base by using a locking device (sup-
plied).
The sounder has four volume settings:
High (90 dB ±3),
Mid High (80 dB ±3),
Mid Low (70 dB ±3) and
Low (60 dB ±3).
The beacon emits a white flashing light and has two
flash rates:
Slow Flash (½ Hz), or
Fast Flash (1 Hz).
The FC430LPBSB LP Beacon-Sounder Base devices are
synchronised, but not synchronous with other sounders
(FC430SB/FC410SNM) and beacons (FC430SAB).
The first flash of the beacon is synchronised with the
start of the tone.
The FC430LPBSB LP Beacon-Sounder Base has a built
in two port isolator.
The FC430LPBSB LP Beacon-Sounder Base requires
two addresses, not including the associated detector.

Category O - open class device (See Table 22 and
Fig. 4). The data applies to both the Slow Flash (1/2 Hz)
and the Fast Flash (1 Hz) while it is fitted with either a
detector or a blanking cap.
The light distribution is cylindrically symmetrical about
an axis at a right angle (Alpha of 90°) to the surface on
which the device is mounted, i.e. when the device is
mounted on a horizontal ceiling, the light distribution is
symmetrical about an axis extending vertically down-
wards through the centre of the device. The light distri-
bution in Fig. 4 represents a cross-section through the
volumetric shape using the values as indicated in
Table 22.

Address Programming
The factory set address is 255. The device should be
programmed with its loop address before installation
using an FC490ST with an ancillary lead that plugs in to
the device's programming port (see Fig. 1).
The FC430LPBSB LP Beacon-Sounder uses two con-
secutive addresses on the addressable loop, starting
from the chosen programmed address number. These
addresses are automatically generated when a
FC430LPBSB LP Beacon-Sounder Base is selected in
FIRECLASS Express.
The address configuration is as follows:
FC430LPBSB LP Beacon-Sounder Base
Configuration
Sounder tone (Device Mode), sounder volume output
(Sensitivity) and beacon flash rate (Device Mode) are
configured in FIRECLASS Express.
Bell Mapping
If it is required for the sounder to operate as a Bell Map
output, then the Group to which the device belongs
must be put into the Bell Map Outputs Supergroup.
To achieve this, select group 50 Bell Map Output SG
and then select “Edit Members”. Use “Add member”
to include the Points group into the Bell Map Output SG.
If the sounder base needs including in any sounder
Walk Test, then super group number 51 “Sounders to
walktest SG”, will have to be edited to add the point's
group to the list of supergroup members.
For the beacon to be included as a visual output con-
trolled by the Bell Map, the points group needs to be
included in ‘Bell Map Visuals SG’, 58.
Output Pulse Pattern
Output pulse patterns are restricted such that the
period between a sounder Low to High transition to the
next Low to High transition is a multiple of the beacon
flash rate period.
Fault Monitoring
Both the beacon and sounder are monitored. The last 2
columns of Table 6, “Sounder Tones,” on page 5,
shows if the sounder is monitored, as a function of vol-
ume setting and system configuration. Sound monitor-
ing is also referred to as Reflective Sound Monitoring
(RSM). For further details on the application of this func-
tion, refer to the Technical Publications of the relevant
Control and Indicating equipment.
Isolator Operation
The built-in isolator serves as a protection device
against short circuits. It operates by isolating the sec-
tion of line containing the short circuit from devices on
the line and from the rest of the line (refer to Fig. 5).

Table 23: Address Configuration

Optimum operation requires the line to be wired as a
loop, so that a section of line with a short circuit can be
isolated between a pair of isolator devices (including
FC430LPBSB LP Beacon-Sounder Base).
In order to enable the isolator’s use in a looped circuit, it
is capable of passing current in both directions:
Loop IN to Loop OUT or
Loop OUT to Loop IN.
In the event of a line short circuit, the line isolator con-
tinues to power its Beacon-Sounder, providing that
either Loop IN or Loop OUT remains intact. When a
short circuit develops, the adjacent isolator devices will
isolate both sides of the loop from the faulty device/
cable.
The operation of the loop driver means that there are
effectively 2 operational modes for the built-in isolator.
When the loop is first powered, if a section of the
line appears as a low impedance (with an equivalent
resistance of <400), the isolator will restrict the
power to that section of line until the fault is cleared.
If a short circuit is introduced onto the line when the
loop is already powered up, in most instances the
controller’s internal protection will switch in before
the line isolator. The voltage is then removed from
the line by the controller, on restoration, the isolator
devices will isolate the low impedance section of the
line.
