4.0 Cabling Requirements
4.1 Detector, Alarm and Auxiliary Wiring
All external wiring associated with the system must conform to the current I.E.E Regulations and
cabling must conform to the relevant BS specifications. ECA recommended Cable Separation for
Electromagnetic Compatibility in Buildings must be followed.
To comply with EMC regulations Protec recommends the use of screened cabling throughout the
installation. The screens must be securely connected to the screwed earthing studs provided inside
the 3300 enclosure.
Screened cables that are suitable for wiring are:
MICC (PyroTM), Pirelli FP200TM, FireTuffTM, or any other cable which complies with BS 6387
(categories C, W, Z).
Proper glanding of the cable is vital to the correct performance of the system.
4.2 Mains Wiring
The 3300 requires a mains supply exclusive to the panel that uses fixed three core wiring (between
0.75mm2and 2.5mm2) which is fed from a double pole isolating fused spur, fused at 3A.
Unauthorised operation of the mains supply should not be allowed and the fused spur should be
labelled “FIRE ALARM: DO NOT SWITCH OFF”

5.0 Installation Procedure
The 3300 fire alarm panel circuit boards are housed in a plastic enclosure. When the front is removed
from the panel the circuit boards and the batteries are fully accessible. The panel can still be
controlled even though the front has been removed.
The panel can be surface or flush mounted.
The panel must be located internally in an area that is not subject to dampness, extremes of
temperature or physical abuse. The environmental limits are given in section 21.0
1) Unpacking
After opening the box remove the installation template and spares pack from the packaging,
leaving the 3300 in the cardboard box for protection.
2) Preparing the Mounting Position
Use the installation template in conjunction with a spirit level to mark out the fixing locations
for the panel. Drill and plug the mounting holes previously marked.
3) Removal of the Door
Remove the 3300 unit from the packaging. Remove the two screw covers from the lower two
corners of the front door and unscrew the two front door fixing screws.
Swing the door upward from the bottom and lift away, see figure 5.0.
Put all removed parts in a safe, dry place.
Figure 5.0 – Removing the door from a 3300.

93-530-70 Issue 0 Page 9 of 44 © Protec Fire Detection PLC 2007
4) Removal of the Main PCB.
NOTES ON ANTI-STATIC HANDLING OF THE PCBs
Before handling any of the circuit boards in the 3300 it is vital that any operatives
discharge themselves of any static charge that may have built up on them. This can be
done by momentarily touching a solid earth point (a non-painted part of a radiator, for
example).
Handle the PCBs by their sides and DO NOT touch the electronic components on them.
The PCB should be stored in a clean, dry place away from the place of work. Retain the
PCBs in a cardboard box for safety until they are required.
Disconnect the 3 way connector from the main PCB, taking care not to strain the connector or
the PCB. Leave the connector attached to the Power Supply PCB.
Unscrew and remove the two mounting screws on the main PCB. Carefully slide the Main
PCB upward (stage 1) and lift away from the plastic enclosure (stage 2). See figure 5.1.
Store all screws and PCBs in a safe, dry place.

5) Preparing and Fixing the Panel Back-box
The mains cable entry position should be kept away from other system cabling.
Carefully knock out the required cable entry positions and mount the enclosure at the position
prepared in (2) whilst feeding the cables into the enclosure.
6) Refitting the Main PCB
Note: Before re-fitting the main PCB the mains power connections to the Power Supply
PCB should be connected. See section 12.0.
DO NOT SWITCH MAINS POWER ON AT THIS POINT !!
Route the battery cables through to the battery compartment using the channels provided.
Replace the Main PCB (a reversal of removal), ensuring it is pushed fully down to the bottom
edge of the panel. Secure with the two screws removed previously. Take care not to over
tighten the screws.
Re-connect the three way cable from the Power Supply to the Main PCB, do not use undue
pressure and ensure the cable is clipped into the locking ramp on the PCB header securely.
7) Re-fitting the Door
Replace the plastic door by offering the top of the door up to the groove at the top of the
plastic back-box.
Swing the door down and ensure it pushes fully home into the back-box, without fouling the
rubber keypad or light-guides on the main PCB. See figure 5.3 for details.
Tighten the two screws in the lower two corners of the door, and replace the screw covers.

6.0 Testing of Cabling Prior to Connection
Before connecting any external cables to any field device (detectors, sounders, auxiliary inputs or
outputs), or the 3300, tests must be carried out using a 500V dc insulation tester (MeggerTM). The
readings between each cable core, and each core and earth should be greater than 10MΩ.
Important Notes:
•Equipment connected to the cabling during insulation tests could be damaged with the high
voltages used during the test.
•Field devices and the 3300 MUST NOT be connected when high voltage insulation tests are being
performed on the cabling, the cabling must be completely discharged prior to connection to any
field devices or the 3300.
7.0 Detector Circuit Connections
Figure 7.0 shows a typical connection regime for a detector zone on the 3300.
Figure 7.0 Typical 3300 Detector Connection
•Ensure the length of the zone wiring is no more than 500 metres.
•Ensure the resistance of each conductor is no more than 15Ω.
•Ensure the capacitance of the zone wiring is no more than 0.27µF (micro-Farads)
when no end of line capacitor is present.
•The end of line unit (8k2 resistor or 100µF/22Ωnetwork) must be placed at the very end of the
detector zone wiring, ensuring the whole zone is monitored.
•Spurs should not be connected from the zone wiring as the spur will not be monitored for open
circuit faults.
•To ensure compliance with EN54 Part 2 each detector base must include a series low voltage
drop diode, such that manual call points following a removed detector still function correctly.
Protec S3000 bases incorporate the diode as standard.
•Manual call points must incorporate a series resistor to ensure the zone does not enter a short
circuit fault condition when the manual call point is activated. If the panel is to be able to
distinguish between automatic and manual zone activations the resistor value in the manual call
point must be 180Ω. In retrofit situations, values up to 560Ωcan be used but ‘MCP fire’ may not
be given in all instances.
Protec 3300 manual call points incorporate the series 180Ωresistor as standard.

8.0 Alarm Circuit Connections
The 3300 has four alarm circuit outputs, all are rated for continuous use at 150mA and protected from
over-load by an auto resetting thermal ‘fuse’. The ‘fuse’ will reset when the cause of overload has
been removed and the alarm output has been de-activated.
Figure 8.0 shows typical connections for a 3300 alarm circuit.
Figure 8.0 Typical 3300 Alarm Circuit Connection.
•Ensure the length of the alarm circuit wiring is no more than 500 metres.
•Ensure the capacitance of the alarm circuit wiring is no more than 0.27µF (micro-Farads).
•The 10kΩend of line resistor must be connected at the very end of the alarm circuit wiring,
ensuring the whole line is monitored for open circuit faults.
•Spurs should not be connected from the alarm wiring as the spur will not be monitored for open
circuit faults.
•Only polarised and suppressed sounders should be used on the 3300 alarm circuits. Failure to
use polarised sounders will result in an alarm circuit fault. All Protec S3000 sounders are polarised
and suppressed as standard.
•Efforts should be made to evenly spread the sounder load across the 4 alarm circuits, to avoid
overloading any one of the alarm outputs.
•It is acceptable to connect alarm circuits 1 and 2 or alarm circuits 3 and 4 in parallel (to obtain a
drive rating of 300mA continuous), however the end of line resistor value must be changed to
4k7Ω1/2W 5%. This is detailed in figure 8.1

9.0 Auxiliary Input and Output Wiring
The auxiliary input connections (Keyswitch, Remote Alarm and Class Change) and auxiliary output
connections (Global Fault and Global Fire) should be wired in screened cable. The screen should be
securely connected to the screwed earthing post provided in the panel.
9.1 Keyswitch Input
The keyswitch input is active when a short circuit (less than 50Ω) is connected across the keyswitch
terminals.
In the standard 3300 this is an alternate method of accessing level 2 functions if the code entry feature
is not required.
The keyswitch wiring should be kept local to the 3300.
9.2 Remote Alarm Input
The remote alarm input is active when a short circuit (less than 50Ω) is placed across the remote
alarm terminals. When activated the 3300 will activate alarm outputs, fast intermittently sound the
internal buzzer and illuminate the ‘General Fire’ indicator. The Global Fire output is NOT activated.
9.3 Class Change Input
The class change input is active when a short circuit (less than 50Ω) is connected across the Class
Change terminals. When activated the 3300 will activate alarm outputs continuously. The Global Fire
output is NOT activated.
9.4 Global Fault Output
The Global Fault output is a set of Volt free relay changeover contacts (rated at 1A 24V dc max.) to
allow interfacing to other equipment. The contacts are normally activated (the N/C and C contacts are
high resistance) and will release when the 3300 has any fault.
9.5 Global Fire Output
The Global Fire output is a set of Volt free relay changeover contacts (rated at 1A 24V dc max.) to
allow interfacing to other equipment. The contacts are normally released
(the N/C and C contacts are low resistance) and operate as follows.
The Global Fire output WILL activate if
•A standard zone has activated (manual or automatic)
•A delayed zone has expired
•A coincidence zone has expired, or a second coincidence zone has activated
The Global Fire output WILL NOT activate if
•A remote alarm activation occurs
•A zone in test mode is activated
•A non-latching zone is activated
•The Sound Alarms button is pressed in access level 2 or 3
