4.2.1. C1626 2/4 Zone Motherboard
This board is common to the 2 & 4-zone panels. It
is also used, in a depopulated form, as the
motherboard for the range of repeaters.
It provides terminals for all the field wiring, interface
connectors for the repeater and connections to the
display board. The power supply components for
the panels and mains powered repeaters are
located on this PCB. The microcontroller (including
Firmware and RAM) and all of the site-specific
configuration features (DIL switch & EEPROM) are
accommodated on this board.
4.2.2. C1627 8/16/32 Zone Motherboard
This board is common to the 8, 16 and 32-zone
panels. It is also used, in a depopulated form, as
the motherboard for the range of repeaters.
It provides terminals for all the field wiring, interface
connectors for the repeater, zonal expansion
connectors and connections to the display board.
The power supply components for all panels except
the 32-zone panel are located on this PCB. The
microcontroller (including Firmware and RAM) and
all of the site-specific configuration features (DIL
switch & EEPROM) are accommodated on this
board.
4.2.3. C1632 16 Zone Expansion Board
This board provides an additional 16 detection
zones. It is connected to the C1627 motherboard
via a ribbon cable to provide a total of 32 zones for
the 32-zone panel.
4.2.4. C1628 16 Zone Display Board and
C1629 32 Zone Display Board
These boards provide visible [LED] user indications
and user buttons. The display board connects to
the motherboard via a ribbon cable.
4.2.5. C1631 Repeater Interface Board
This optional plug-in board provides an RS485
capability for communication with up to 5 repeaters
and is fitted to the C1627 motherboard via two
connectors. One C1631 needs to be fitted to the fire
alarm panel and one to each repeater.

7. Precept EN C1632 16 zone expansion board Features
Figure 11 llustrates the motherboard features referred to elsewhere in the documentation
Figure 11 – C1632 16 Zone Expansion Board
8. Power Supplies
The 1.5A, 3A and 5A power supplies provide 27.1V
nominal at load currents of up to 1.5A, 3A and 5A
respectively and are designed in accordance with
the requirements of EN54-4.
The Precept EN 2, 4, 8 and 16 power supplies are
contained on the C1631 motherboard, see Figure
10. The Precept EN 32 zone panel power supply is
on a separate board (C1652) mounted inside the
fire alarm panel enclosure, see Figure 12.
8.1. Battery Charger
Each power supply provides a temperature-
compensated charging voltage for sealed-lead-acid
12V batteries connected in series. Charging voltage
range is 26.72V @ 50oC to 28.25V @ -10oC.
Battery sizes are:
2 off 12V, 3Ah for the 1.5A supply
2 off 12V, 7Ah or 12 Ah for the 3A supply
2 off 12V, 18Ah for the 5A supply
The health of the batteries, the battery connections
and fuse are checked by a battery monitor circuit
and automatic battery test facility once every 30
seconds. If the Battery is disconnected or the
Battery voltage falls below 15.7V or the Battery and
inter-connection resistance is greater than or equal
to 1Ω, the Batt/Charge fault LED is illuminated and
the Fault Output is operated. The circuitry also
protects against reversed connection of the
batteries.
8.2. Visual indications
Visual indications on the power supply are:
1) A green ‘Output- OK’ LED. This simply
indicates that power is being supplied to the
load.
2) A yellow ‘Batt Charge Fault’ LED indicating
any of the following conditions:
a) Battery or associated wiring disconnected
b) Battery fuse blown
c) Low Battery voltage (<15.7V ±0.4V)
d) Battery and interconnection resistance is
equal to or higher than:
•1Ω - 2/4-zone panels & repeaters
•0.6Ω - 8/16-zone panels
•0.35Ω - 32-zone panels

3) A yellow ‘Charger Fault’ LED (‘Internal Fault’
LED on the C1652 PSU board) indicating any
of the following:
a) A mains fault exists (described below)
b) The Switching regulator or charger circuitry
is malfunctioning
c) Battery Fuse is blown
4) A yellow ‘Mains Fault’ LED. This indicates that
the mains voltage has failed or is less than the
required minimum for correct operation of the
power supply (80% of the rated voltage).
8.3. Fault Outputs
All PSU fault conditions are communicated to the
panel motherboard, which will raise a fault
indication on the display and operate the fault
routing output.
8.4. Battery Disconnect
The power supply provides a battery disconnect
facility that disconnects the batteries when the
battery terminal voltage falls below 21.2V ±0.53V.
This will occur under the following conditions:
1) A short circuit across the battery terminals
2) To prevent deep discharge of the batteries if
supplying the panel for an abnormally long
period of time.
The batteries are reconnected when the mains
voltage is present and the battery voltage is greater
than 18.5V ±0.46V.

Notes:
The Precept EN panel is designed to monitor 22µF capacitors as end-of-line devices on the zones. If the
zone is configured as an Intrinsically Safe zone then the end-of- line device must be changed to a 10k
resistor. In this case the following limitation must be observed:
•The total current drawn by detectors on a zone must not exceed 1.2mA, otherwise the panel may
not detect an open circuit fault on the zone wiring. The standby current drawn by each device will be
given in the manufacturer’s datasheet for the device. To calculate the total number of devices that
may be connected to a zone, add up the individual standby current values for each device and
make sure that the total current does not exceed 1.2mA, including the current drawn by the I.S.
barrier.
•If a galvanic isolator (MTL5061) is used on the zone then this device will draw current. Allow at least
0.1mA for the barrier (this could rise to 0.4mA depending on how much current is drawn by the
detectors).
•The maximum number of devices per zone must not exceed 32, regardless of standby current.
The values in the above table are for guidance only and will vary for individual detectors. Each zone should
be fully checked for correct fault monitoring during installation & commissioning.
