1 Introduction
These installation instructions describe the hardware connection facilities of the CM+ fire alarm
control panel, in detail and with specifications, wiring requirements, tips and EN54-2
requirements.
Once the control panel has been fully connected, it has to be told what hardware connections
will be used. The relay functions have to be chosen and various general settings made. The
CMPlus.exe program is used for this, preferably before or during set-up.
The CM+ fire alarm control panel complies with European standard EN 54 Parts 2 and 4.
In Belgium the installation must also comply with the regulations in accordance with the NBN
S21-100 standard. (NEN 2535 for the Netherlands)

2 Installation
2.1 Removing the cover
The cover can be removed without using tools.
Place your fingers under the housing between the clips and the housing and pull the lower edge
away from the housing. Gently push the cover upwards so that it comes away from the top
pivots. Carefully pull the operating panel connector out of the main PCB.
(Replacement of the cover: in reverse order; do not forget to place the screw)
2.2 Installing the housing
Install the housing at eye level and in an easily-accessible location.
The housing must not be installed where there is a risk of it being splashed or soaked with water
The ambient temperature in the location must be between -5 °C and 40 °C, with a relative
humidity of between 0 and 95% (non-condensing).
The housing must be attached to a wall that is as flat as possible, in order to prevent distortion.
Use spacers at the attachment points if the unevenness of the wall is greater than 3 mm. It will
be difficult to fit the cover to a distorted housing and the operating panel could be damaged.
Ensure there is at least 10 cm clearance around the housing to allow proper air circulation.
There is a gap of 12 mm on the wall side and an internal gap of 22 mm, allowing wiring to enter
the housing from any direction. The breakout edges at the top or bottom can be cut away before
installation if necessary, to enlarge the cable entry by 5 mm and 10 mm respectively.
Mark the positions of the holes and attach the box, using ø 4.5 or 5 mm screws.
Housing dimensions: 340mm x 266mm

3 Connecting the mains power
The fire alarm control panel must be connected to the 230 V AC mains via a double-pole circuit
breaker in the electrical distribution cabinet.
The cable must be at least 2 x 1.5 mm2, and must be separated from the rest of the control
panel wiring as much as possible. Strip the outer sheath of the cable as little as possible, so that
should one of the conductors become loose it cannot touch the control panel’s 5 V or 24 V parts.
Fasten the cable in the place provided.
The installation may only be switched on during its commissioning.
4 Connecting the batteries
The batteries are sealed lead-acid batteries rated at 1.2, 3 or 7 Ah. Two 12 V batteries are
connected in series to provide 24 V.
The control panel has an integral automatic battery charger. The charging current is limited to
0.86 A and the charging voltage is regulated according to the temperature in order to maximise
battery life. The battery fuse is F2 on the main PCB: 3AT
The charging current is cut off in the event of an alarm, as allowed by EN54-4, which means that
there is more power available for the external devices.
The batteries are tested every 8 minutes. If a battery can no longer be charged or its connection
is loose, or if its internal resistance is very high, then a battery fault is indicated automatically.
Battery testing is also performed 30 seconds after every reset.
Sealed lead-acid batteries have an average service life of 5 years in this application, after which
their capacity falls drastically or they become faulty. It is therefore best to replace them within
this period. Write the date on a battery when it is installed as a replacement.
Batteries may only be connected during the commissioning of the installation.
If no batteries have been connected, the battery charger will switch on briefly at regular intervals.
If the batteries are nearly discharged and there is a high current demand, the charger will switch
to an on/off regime in order to limit internal heating.

Calculating autonomy
The battery capacity is chosen as a function of the desired autonomy of the fire alarm system in
the event of a mains failure, for example 24 or 72 hours.
First calculate the total power consumption.
main PCB: 7.5 mA +10 mA per activated relay
zone in operation: 5 mA
relay PCB: 6 mA per activated relay
integral operating panel: 3.5 mA
External operating panel: 3.5 mA
current for external devices: e.g. door magnet 75 mA
Example: CM+ with 10 zones, 1 integrated and 1 external operating panel, 1 door magnet = 56
mA+ 3.5 mA+ 3.5 mA+ 75 mA = 148 mA = 0.14 A
Assuming that autonomy has to be for 24 hours: this means that the capacity required is 0.14 A
x 24 hours, which is 3.4 Ah.
The batteries must furthermore be capable of supplying power for 30 minutes in the event of an
alarm:
for example with 10 sirens rated at 40 mA: 10 x 0.040 A x 0.5 hours = 0.2 Ah
A safety factor of at least 1.2 is applied to arrive at the capacity required:
1.2 x ( 3.4 Ah + 0.2 Ah) = 4.3 Ah. A 7 Ah battery set would therefore be a good choice.

5 Zone connections
A maximum of 32 alarms can be connected on each zone.
The NBN S21-100 installation standard does not permit manual alarms (push-buttons) to be
connected to the same zone as automatic alarms (detectors).
Each zone has only one beginning and one end. The last detector or the last push-button must
be fitted with a 4k7 end of line resistor (supplied with the control panel). Branching of the line is
not permitted.
The end of line resistor must only be connected directly to the main PCB if the zone is not used.
Zones that are not used can be switched off completely using the CMPlus.exe program, in which
case the end of line resistor does not have to be used.
6 Sirens
Use fireproof type Rf cable.
Connect the sirens to the 'siren1' and/or 'siren2' monitored outputs. Note that each siren circuit
must be completed with a 1 kohm resistor (supplied with the control panel).
The end of line resistor must be connected directly to the main PCB if the siren circuit is not
used.
The output is electronically secured and the maximum permitted current is 0.7 A per siren circuit.
It is assumed that each siren has at least two built-in series diodes so that the sirens do not
interfere with the line break measurements and they do not begin to sound. This requirement is
met automatically when Argina sirens are used. With other sirens it can sometimes be
necessary to fit a diode (type 1N4007) in series with them.

7 24 V output
External devices can be connected to this output.
The output is electronically secured and the maximum permitted current is 500 mA.
The precise way the output operates can be altered by using the CMPlus.exe program. For
example, it can be arranged that the 24 V output is interrupted when the fire alarm control panel
is reset, e.g. for supplying and resetting beam detectors.
8 Relay output
The standard configuration is 3 potential-free relays, each of which can switch 30 V / 1A.
They are freely configurable using the CMPlus.exe program.
Caution: a relay programmed as a fault output is normally always closed. If a fault occurs or the
control panel fails completely, then the relay is de-energised.

9 Switch loop
Up to 4 contacts can be connected to the fire alarm control panel. Each operating panel and the
fire alarm control panel itself has a monitored input loop to accommodate them, and can be used
for example for reading a reset switch with a triangle key as used in the Netherlands, or an
external buzzer stop switch. The loop is fully monitored for short circuits and line breaks.
The end of line resistor must be connected directly to the main PCB if the input loop is not used.
10 Pager output / serial connection with the PC
PC connection for setting up the control panel using the CMPlus.exe program or for use as a
pager output. The CM+ selects the correct mode automatically.
!! Use screened cable; maximum cable length is 2.5 m (RS232 5 V levels)
female sub D - 9p
do not use a crossover cable!
10.1Pager settings
Only data is output in this mode –connect the pager to the Do and GND terminals.
The Di terminal is used for automatic selection of the mode; it is safer not to connect this to a
pager system.
RS232 settings: 9600 baud, 8 data bits, 1 stop bit, no parity.

The strings the pager sends always begin with ‘#’ and end with ‘\r’ (0D hex).

11 Operating panel
The operating panel can be used for the complete operation of the control panel. Simple settings
such as delay times can be entered from the operating panel. The CMPlus.exe program is used
for more advanced settings.
The labels in the label pockets can be changed, for example for indications in another language.
See the end of this manual for labels in other languages.
