LPCB APPROVED CFP ALARMSENSE 2/4/8 ZONE FIRE ALARM PANEL

SECOND FIX

Connecting the panel

Connecting the panel's internal connections and PCBs should be undertaken immediately before commissioning.
Before you begin, we recommend you check all devices on the zone circuits and conventional sounder circuits are
correctly connected (see pages 7 and 8) and that cable integrity is verified throughout the installation.
Important: DO NOT use a high voltage insulation tester with any electronic devices connected.

Installing the Power Supply PCB

The panel's Power Supply PCB combines the functions of a Mains input to regulated DC power supply unit, battery
charging unit and battery monitoring unit.
WHEN CONNECTED, THE POWER SUPPLY PCB STORES VOLTAGES AT UP TO 400Vdc AND MAY BE
LETHAL IF TOUCHED. DO NOT TOUCH THE PCB WHILST THE RED 'HAZARDOUS VOLTAGES PRESENT'
INDICATOR IS LIT.
Under no circumstances should the fire alarm panel be operated without the Power Supply PCB correctly mounted
in the panel's enclosure and the three retaining screws securely tightened.
The PCB should be positioned in the panel as shown in figure 8 on page 11.

Connecting the Mains

The general requirement for the Mains supply to this equipment is described on page 6.
DO NOT attempt to connect Mains to the panel until you are fully conversant with the layout and features of the
Power Supply PCB, as described above and in figure 8 on page 11.
The incoming Mains cable should be brought into the panel at the top right hand side of the enclosure and
terminated at the connector block (CONN1) on the Power Supply PCB.
Make sure the Mains earth wire is connected directly to this connector block and NOT to the base earth distribution
post which is provided for making off zone circuit and conventional sounder circuit screens.
The Power Supply PCB's earth distribution strap MUST be connected to the spade on the base earth distribution
post before operation. The spade is compressed against a shoulder on the post via the lowest nut. The base earth
distribution post may appear loose, this is intended by design.

Connecting the standby batteries

There is a risk of explosion if incorrect battery types or sizes are used. Always replace both batteries
and always dispose of used batteries in accordance with the battery manufacturers instructions and
local regulations. Batteries are heavy and can produce dangerously high currents if shorted. Take
care when handling and routing battery leads to avoid damage.
Note: LPCB approved systems must use 3.2Ah batteries (YUCEL Y3.2-12).
Two new, good quality and fully charged 12V valve regulated lead acid (VRLA) batteries are required as the
emergency standby power supply for the panel.
The batteries should be connected in series and located in the panel's enclosure as shown in figure 9 on page 11.
The battery leads, link wire and nylon cable ties are supplied in the panel's accessory pack. Run the battery leads
through the slits in the panel's lower plastic ribs and secure the batteries into position using the nylon cable ties.
The panel's sophisticated battery monitoring unit protects the batteries against deep discharge by activating a cut
off circuit when the standby supply voltage reaches 21V approx. If batteries are not fitted, are discharged or in
poor condition, a PSU fault will show at the fire alarm panel.
The capacity of the batteries used will depend upon the required standby time. To calculate the batteries required
for any given standby period, please refer to the calculation guide on page 23.
