1. INSTALLATION & CABLING RULES
Before mounting the panel you must decide on the place of installation. The use of remote keypads mean
that the panel can be located anywhere on the premises and it is recommended that the panel be housed in a
concealed place.
IMPORTANT:
1. Before any work is undertaken it is highly recommended that the mains supply be isolated to
reduce the risk of electric shock.
2. Before handling or touching any of the bare PCBs, you should make every effort to reduce the
amount of static electricity that the boards may be exposed to.
1.1 Tools Required
The Matrix alarm panel and associated devices use standard screws for all serviceable parts. No other special
tools are required.
Action / Serviceable Part Tool Required
Remove the case lid (panel + expanders) Pozi-drive No.3
Mains input terminals Slotted 4mm
Zone terminals (panel and expanders) Slotted 3mm
Battery terminals on main PCB Slotted 3mm
MX-BATT terminals Slotted 3mm
Remove LCD/ICON keypad rear cover Pozi-drive No.0
1.2 Mains Wiring
The matrix panel has a standard 3-way mains input connector block with integrated supply fuse protection.
The connector block connections are indicated on the panel case with an associated mains input sticker. This
sticker indicates Live (L), Neutral (N) and Earth, as well as the mains supply voltage rating.
1.3 Zone/PGM Wiring
To minimise false signals on the zone connections it is recommended that no part of the wiring be allowed to
short to adjacent connectors. Strip back only enough sleeving from the wire as necessary before inserting it
all the way into the connector, as far as it will go. When placing more than one wire into a single terminal
make sure that all the wires are pushed in firmly as far as they will go, before tightening the terminal screw.
Do not join multiple wires together before inserting into the terminal block, as this is a common cause of
faulty wiring causing false alarms.
When linking out unused zones with resistors, again make every effort to ensure that adjacent resistors
cannot short out with each other. Keep the resistor leg length short and do not allow resistor legs to overlap
with each other.
1.4 Battery Wiring
The battery wiring is very similar to the zone/PGM wiring as the same type of terminal connections are
employed. If you are using an MX-BATT battery monitor board then you will be wiring to the MX-BATT BAT
IN connector and not to the Matrix alarm panel PCB.
The battery connection is polarized. You must ensure that the positive terminal of the battery is connected to
the BAT+ terminal on the Matrix alarm panel (BAT IN+ on the MX-BATT PCB), and that the negative terminal
of the battery is connected to the BAT- terminal on the Matrix alarm panel (BAT IN – on the MX-BATT PCB).
1.5 Battery Maintenance
The Matrix alarm panel constantly monitors the battery voltage and will provide suitable battery low/fail
warnings in the event of a battery problem. A system fault 4 indicates a low battery. System fault 3 indicates
a missing/dead battery. When replacing a battery only use the recommended battery type and rating. See the
Technical Specification Section for full details.

1.6 Low Battery Voltage Detection
The Matrix 424 and 832 printed circuit boards now have a low voltage battery disconnect feature, which
provide monitoring of the battery. The area circled shows the low voltage detect relay and switch.
If the control panel is operating only on battery (for example after a mains failure) the battery will
automatically be disconnected if the voltage drops to 10.5V, this saves the battery from going into deep
discharge.
The switch can also be used to enable a battery voltage to the control panel, if a battery is connected before
the mains.

1.7 Mounting Procedure for Matrix – Plastic & Metal Case
The following steps illustrate basic mounting procedure for matrix plastic & metal case. (See Section 2 for
complete wiring diagrams)
Step 1 - Remove the case lid from the matrix panel and check all parts and components are in place.
Step 2 - Decide where the matrix panel will be situated. The matrix panel may be housed in the loft or
different rooms in the premises. A discrete and concealed place is advisable, as only the Matrix keypads need
to be seen.
Step 3 - Secure the matrix panel to a sturdy and stable surface, using the mounting screws provided. First
mark the wall where the panel is to be situated (using the mounting holes), drill holes in the wall, and fasten
the panel base to the wall using the screws supplied.
Step 4 - Before the panel base is completely secured to the wall feed cables for keypads / AC power supply /
and accessories through the cable entry holes as illustrated.

1.8 Battery Installation Procedure
Place two foam pads on the bottom of the battery and two on the upper rear. Place the battery in the case
and secure with two tie wraps.
1.9 Cabling Rules for the Matrix Bus
Care must be taken when connecting devices to the bus over long cable runs. This is to ensure maximum
system integrity under all circumstances (battery backup, etc.). Pyronix recommends using standard 0.22mm
cross sectional area, shielded multi-core alarm cable for the Matrix bus.
The maximum number of external devices connected to the bus on any one system is limited to
six - this may not be exceeded. Although six is the system limit other restrictions apply to each cable run. It
is important to restrict the amount of current carried along each length of cable to limit voltage drops across
the system. Apart from being affected by current magnitude, voltage drops are also dependent upon the
length of cable and the types of devices fitted. The following tables provide a means of determining suitable
cable run configurations for different systems.
NOTE: It is the length of cable between panel and end device that is important rather than the overall
length on the entire bus.

*1 The Above KEN assignments for Relay type output modules assume that all power supplying the switched
contacts (devices switched on/off by the output expander) is supplied via a different feed/ PSU.
*2 Remember that the maximum allowable current-draw from the Matrix for External devices is 0.6A (plastic
case) / 1.1A (metal case). Any requirement exceeding this must be provided by a separate power supply.
Where a power supply is added for use with an output expander, the 0V of the supply should be connected at
the expander.

1.9.3 System Examples
A Matrix System is required to provide the following:
6 PIR Detectors (15mA each)
A bell-box (max. current draw 400mA) connected to PGM1
2 Matrix ICON Keypads (60mA each), one 50m away, and the other 100m away
A Matrix Transistor Output Expander (30mA) with 3 LEDs (10mA each) and 3 buzzers (12mA
each) controlled by the outputs (accompanying the keypad 100m away) power supply.
From the above example, the total current drawn from the panel would be:
TOTAL Detectors Bell RKPs Output
Expander LEDs Buzzers
0.706A 6 X 0.015 1 X 0.400 2 X 0.060 1 X 0.030 3 X 0.010 3 X 0.012
The maximum current available for external devices from the Matrix PCB is 0.6A. Therefore, this installation
would require an additional power supply.
Before we can calculate an acceptable wiring arrangement we must know the ‘KEN’ value for each device on
the keypad bus. From Table 1 we know that each keypad has a KEN of 1. The Transistor Output expander
controls the LEDs and buzzers, which together give a total current of 66mA (3x10mA + 3x12mA). From table
1 a transistor output expander with a current sink of 66mA falls into the <90mA criteria which corresponds
with a ‘KEN’ of 2.

Matrix 424, 832, 832+ Installation Manual
Page 6 RINS918-6
Example 1
The most straightforward wiring approach would be to daisy chain the devices on one run as below.
However, this is an unacceptable solution because there are 4 ‘KEN’ on a 100m length of cable. Table 2
shows that a maximum of 3 ‘KEN’ is acceptable on a 100m length of cable – the fact that one keypad is just
50m away does not affect these rules.
Example 2
This is now an acceptable solution because the ground return is shared between 2 cores of cable. Referring to
table 2, the second column shows that by doubling up the ground return it is acceptable to have up to 4 ‘KEN’
on a 100m length of cable.
Example 3
This is now an acceptable solution because there are now two separate cables connecting the devices back to
the Matrix control panel. The 100m cable is now supporting 3 ‘KEN’ and is now in accordance with table 2,
and the 50m cable is supporting 1 ‘KEN’ which is well within the limits.

1.10 Addressing the Keypads & Proximity Readers
The LCD and ICON keypads are individually addressable. Each keypad type (LCD & ICON) can have four
different addresses. The address of the device is set using the small switch on the keypad PCB. If you have
multiple devices of the same type then they must have different addresses (IDs). One keypad MUST be set to
ID 1. You will need to remove the rear cover from the keypad to gain access to the address switch.
The Matrix panel recognizes individual MX PROX readers by the link settings on the back of each reader.
NOTE: Before you start programming the system, use engineers function 754 to scan for all devices
on the Matrix bus.
1.11 Finding Bus Devices
Every time you add or remove a device on system bus, you must rescan for bus devices ()
so that the panel can recognise the new hardware.

2. WIRING DIAGRAMS
GLOBAL TAMPER CONNECTION
Note: The global tamper connections are very important.
The global tamper connections on the 832 and 832+ control panel are GT and AUX-, devices
should be connected between these two terminals to create a global tamper loop.
The 424 control panel does not have the GT terminal connection, so a spare zone programmed
as Tamper should be used to create the tamper loop.

2.4 Power Supply Wiring
NOTE 1: Terminal connections for the Matrix 832 and Matrix 832+ are the same as for the Matrix 424.
NOTE 2: When the control panel is de-energized, you can apply power from either of the power
supply inputs: AC supply via the transformer or 12V DC supply from the battery.
NOTE 3: If necessary it is possible to power the panel using only the +BAT- terminals. In this case it
is recommended that a 12V UPS (uninterruptible power supply) is used. AC Monitoring option should
be disabled.
2.5 Telephone Line Wiring
Terminal connections for the Matrix 832 and Matrix 832+ are the same as for the Matrix 424.
NOTE: Terminals R-1 and T-1 are used for connecting to telephone line equipment which will
automatically be disconnected from the telephone line during dial out and UDL session.
