at the Display PCB).
- Remove the front cover as follows: with the door at an angle to the enclosure of between 30° and
40°, carefully lift it clear of the two hinge pins - DO NOT force it. If the door does not move up easily,
the angle is too small or too large, so adjust the angle in either direction until the door lifts easily.
- If the medium enclosure is to be installed remove the lower cover by moving upwards and pull away.
This cannot be removed with the main cover in situ.
- The Base card or PSU do not need to be removed from the enclosure if the provided knockouts are
to be used. If additional access holes are to be made it is recommended that the Base PCB and PSU
are removed to avoid inadvertant damage or contamination.
- Remove the necessary knockouts for the installation cabling.
- Mount the enclosure in the desired location using all three mounting holes A (small enclosure) or B
(medium enclosure).
- Use a drill bit diameter 7.0 mm and a suitable 40 mm long expansion plug. Fix the panel to the wall
with No. 10 screws length 1½” or M5 screws length 40 mm.
- Install the external wiring into the enclosure using the appropriate glands/ conduit fittings.
- Sufficient knockouts are provided at the top of the enclosure. Refer to wiring sections for recommended
positions.
- If you punch out other holes, be sure that they do not interfere with any component mounting positions.
- Use a brush to clean any dust and swarf from inside the enclosure before re-fitting the main door.
To avoid distortion of the back box when preparing knockouts, place the appropriate back
box face on a supporting surface (e.g. work bench).
3.2.1 Position of Knockouts

- Refer to the Product Market Variations Manual for details of local standards requirements that apply to
the inspection and testing of installation wiring.
All installation wiring MUST be checked PRIOR to termination in the panel.
The following checks are recommended:
- Check the continuity of all cable runs (including cable screens).
- Check the impedance of all signal cable runs. Ensure that, in alarm mode, any voltage drops
induced do not compromise device operation or compatibility. Ensure that cable impedance
does not exceed any specific requirements detailed in the remainder of this document.
- Check the isolation between all cores and between cores and screen/earth. Minimum
isolation of 2MOhms is required.
- Check that the screen of all signal cables is not grounded to earth elsewhere in the
building and that it is installed in accordance with recommendations – refer to relevant
wiring installation sections in this document for more information.
- Check that signal cables are not run in cable trays, or the like, alongside power cables for
this and other equipment.
3.4.3 Mains Power Input
- The DX Connexion Series Fire Alarm Control Panel receives power from a single-phase, 230V,
50Hz, mains supply. The mains input terminal block is located on the PSU-mounting bracket and in
the same way for all DX Connexion Series variants.
- The incoming power feed cable Ground or Earth (Green/Yellow) wire should be connected to the
mains terminal block earth connection – middle terminal.
- Connect the neutral (Blue) wire to the top terminal and connect the Phase or Live (Brown) wire to the
bottom terminal. The mains terminal block contains an integral fuse to provide the required over-
current protection. Rating of the fuse is quoted on the label (located on the front of the PSU-mounting

3.4.4.2 Small Enclosure Arrangement
- The diagram opposite shows the position for the
7Ah batteries in the DXc1 Series panel.
- For battery sizes greater than 7Ah, use the medium
enclosure models DXc2 or DXc4.
- Alternatively, the batteries should be installed in a
separate enclosure suitable for Fire Protection Use,
such as Battery Box 797-025-001, with wiring
connected to the panel through conduit.
Figure 8 - Small Enclosure 7Ah Battery
Installation
When the batteries are connected the panel performs a battery wiring integrity test. If
this test fails BATTERY WIRING FAULT is displayed on the LCD. Check for poor battery
wiring connections and remedy. If the batteries require charging the test is suspended
for a period of up to 12 hours and re-applied. If the batteries have not reached the
required minimum voltage the warning is displayed to indicate that the batteries may
need replacing.

3.4.4.4 Battery Operation
- The main microprocessor of the panel periodical checks the state of the AC Mains, battery and
charger circuit. The panel will automatically switch over to the standby battery source when the AC
Mains fails.
- When the panel is operating from AC Mains, the panel checks the output of the charger and whether
the battery is present. To do this, it momentarily turns off the charger output and checks the battery
voltage (battery missing if <15.0V). In a fire alarm condition, the charger is turned off to provide
additional current to the outputs.
- When the panel is operating from the battery standby source, the panel will indicate when the
battery is low (<21.5V) and will automatically switch off the standby power to prevent irreversible
damage (deep discharge) to the batteries (<20.0V).

3.4.5 Detection Loops
3.4.5.1 General Information
- The control panel supports analogue detectors with a data transmission system. It provides power
andcommunicates with theinitiating devices overa two-wire circuit.Allsignallingloopscommunicate
with the panel using a proprietary protocol. In some market regions the selection of protocol
manufacturer is not available. Refer to the Product Market Variations Manual for details.
- The number of detection loops provided on each of the panels is as follows:
Model No. of Loops Enclosure Size
DXc1 1 Small
DXc2 2 Medium
DXc4 4 Medium
EN54-2: 13.7
Maximum of 512
sensors/ MCPs
per panel.
EN54
!
- It is possible for up to 800 addressable input points to be
connected to the DXc4 Series panel.
- To comply with EN54-2 requirements, a maximum of 512
sensors/ MCP’s (input points) only should be connected to
the control panel across all analogue detection loops. This
limitincludesanyconventional detectors/ call pointsconnected
to the system via zone monitors.
- Thepanelconforms with therequirementsof EN54-2 forMCP
alarm input response time.
The detection circuit should be separated from other cable runs to minimize the risk
of external interference. Under extremely noisy conditions, twisted pair wire is
recommended to further reduce interference.
The Detection Loop Circuits are supervised and power limited.
3.4.5.2 Cable Requirements
- Shielded cable must be used for all detection (SLC) circuits. It is important that the shield is always
terminated to a good earth connection at both ends of the loop – earthing connection points are provided
in the enclosure for this purpose. The shield should never be connected to any other earth point in the
building. Refer to Appendix 1 Specifications for guidance on recommended fire-rated cables.
- The core size, length of wiring run and detection circuit loading will produce a voltage drop along the
length of the cable. To determine if the loop driver can fully support the planned loop configuration,
use the detector manufacturers’ calculations for voltage and capacitance.
ALWAYS check that conductors of appropriate diameter are used so that the voltage
at the detectors is within the detector manufacturer’s specification.
The maximum permitted impedance for the SLC Loop is 40 ohms. This must be
reduced if loop powered sounders are installed.
- The following table lists the maximum recommended cable loop lengths for each detection loop
using the indicated cable conductor sizes. Wiring to external devices should follow the appropriate
manufacturer’s instructions.
EN54-2: 7.1.3
Maximum of 10
secs to respond
to MCP alarms.

Table 2 - Maximum Loop Lengths
- Cable runs in excess of 2km (6400’) are not recommended. Otherwise, cable capacitance (Max.
0.5μF per loop) and inductance may start to interfere with data transmission. Refer to the
manufacturers’ quoted figures for maximum cable capacitance.
3.4.5.3 Loop Wiring Installation
·- The SLC (detector) circuits should be installed as loops with or without isolator modules. The wiring
details are as described below.
EN54-2: 12.5.2
Maximum of 32
sensors/ MCPs
between isolators.
EN54
!
For best results and system integrity:
The detection loop circuit should be wired as a loop with
short circuit isolators. This will allow the system to still
function, even if a section of the cable becomes short
circuited. It is recommended that short circuit isolators
be fitted to the detection loop to prevent an external short
circuit from removing more than 32 addressable points
from the system.
- The detection loop connections are made
on terminal blocks at the top of the base
card. The diagrams opposite show the
location of the terminal blocks and typical
wiring connections.
- The DXc1 variant has only one connector
available – i.e. Loop 1. The DXc2 and DXc4
have four connectors available – only Loops
1 and 2 are used on the DXc2.
- Form the loop by taking wires from the
positive and negative terminals, at one side
of the connector on the base card – see
opposite.
- Proceed with installing wiring, around the
loop, connecting all devices – see below.
- Return the wiring to the positive and
negative terminals at the other side of the
connector on the base card.
- Ensure that all devices connected to the
loop are correctly oriented for positive and
negative connections.
- Refer to the detector manufacturers’ data
sheet supplied with the signalling device.
