• Each ZONE can be set acco ding to ope ating LOGIC:
The logic used are the typical logic functions (AND, OR), management of adjacent sensors
(CORR.CON, CIRC.CON). Note that PARK-ITA is a unction only or Italy (Italian Ministerial Decree 01/02/1986).
• Each INPUT (Senso ) is self-p otected and has a FAULT signal:
All sensors inputs are protected against short-circuit or wire breakings. If a short-circuit occurs,
the power supply to that input, is automatically stopped (all others continue to work properly). At
the same time, the FAULT signal is activated.
• Each Senso can be configu ed in two ways:
P econfigu ed Setup: Here you can choose one of the models of our production, (See list in Table
on page 4 ), which is then automatically set in the configuration recommended by the respective
thresholds and relay outputs. Is enough set the output number (relay) to complete the
configuration. The manual changes are, however, permitted.
Gene al Configu ation: Here you can configure any type of sensor (compatible or a new model
not yet listed), manually entering all parameters.
• The AUX input is configu able and can be associated with a elay output:
- Can be configured to activate one of the available relays and can be used by devices with NO or
NC contact outputs (gas sensors with a relay contact, smoke sensors, buttons, etc.).
• The CE424 can manage up to 5, 9, 17 o 25 Ala m elays:
Each sensor has three alarm levels (Th eshold 1, Th eshold 2 and Th eshold 3) and a FAULT,
freely addressable to any relay output.
• The ala m th esholds can be configu ed with special mode of ope ation:
For use in car parking "PARKING EN" (EN 50545-1) or to the workplace, such as exposure limit
value TLV.
• Each output ( elay) can be configu ed as follows:
- Silenceable: the output is disabled for the Silence time, when RESET is carried out and the
sensor is above the set threshold. This function can, for example, be used for the outputs
connected to audible warning devices.
- Silence Time: is the time, adjustable rom 0 to 300 seconds, so Silenceable output (e.g. relay connected
to a siren) is disabled when the RESET is performed and a sensor is above the set threshold
- Hyste esis ON: is the delay, adjustable rom 0 to 300 seconds, of the relay, associated with an alarm
threshold.
- Hyste esis OFF: is the delay, adjustable rom 0 to 300 seconds, of the relay to return to normal
condition, when it ends the alarm.
- Time ON: is adjustable rom 0 to 300 seconds. This function can only be used if you want to stop the
alarm output after a finite time, even if the sensor remains above the alarm threshold set (This
function cannot be used in conjunction with Hysteresis OFF delay). For example you can use it
to enable devices that cannot be powered down, or to send a pulse to a phone dialer.
- Memo ized: the relay remains in alarm, even if the sensor returns below the threshold (this
function does not work if the Time ON or into Hysteresis OFF has already been inserted a value
other than zero), to return to normal conditions must be done RESET. Serves, for example, to
prevent the accidental or unauthorized resetting of a block valve of the gas, without first checking
the cause of the alarm.
- Positive Logic: the operation of the relay can be set normally activated or in positive logic,
therefore, if the relay fails, or is completely out of power, automatically moves into the Alarm
position, the NC contact becomes NO.
• The CE424 have a BUZZER inside:
The internal Buzzer sounds a Beep every touch of the keyboard. It can also be set to sound in
case of Fault and / or Alarm.

ELECTRICAL CONNECTIONS
The electrical connections should be executed all on the housing base.
The details of the connections to the mains, the two batteries, the AUX input and relay output
R9 are illustrated in Figure 3
While the details of the connections to the sensors and the other
outputs are illustrated in Figure 4.
The terminals are of "polarized inlet" type (1). We suggest to use
lugs adequate to the conductors (2) and to fix the wires to the box
structure to avoid excessive stress to the circuits and to the
terminals. Use a screwdriver (3) with the right dimensions.
Considering that, it should be normal procedure disconnect power to the electronic equipment when
installing, or changing the connections, or when disconnecting or connecting expansion cards.
IMPORTANT: TO AVOID IRREVERSIBLE DAMAGE, DISCONNECT THE POWER
SUPPLY TO THE CONTROL PANEL, MAINS POWER AND BATTERY (IF PRESENTS)

Only if necessary, for maintenance or installation requirements
, the housing cover can be
separated from its base, first remove mains power and remove the batteries
, then disconnect
the flat cable, press on the two side tabs as shown in Fig 3.
Then you need to release the cover
from sliding hinges (press fit). To reconnect it, proceed in reverse order and after hanging up
the lid hinges, push the flat cabl
e into the connector, respecting the polarization, the two levers
close automatically locking it. Only then you can reconnect power supply.
BATTERIES: Inside the housing, it can also accommodate two 2V/ .3Ah Lead batteries connected in
series (Fig 3) to assure the system powering in case of mains blackout. The battery life is about 30
minutes with 8 sensors. (The batteries are not included in the delivery, but are available on request).
f required, to increase the autonomy (6 hour), it can be used two 7Ah batteries connected in
series, but causes the greatest dimension, shall be installed in a case outside the CE408P.
Cable glands: the lower side of the housing has 13 inputs designed for metric cable glands (ISO
pitch 1.5 mm). N.10 are for glands M16x1.5 mm (that accept external cables Ø 4÷8 mm) and n.3 are
for glands M20x1.5 mm (that accept external cables Ø 6÷12 mm).
These passages are closed, but they are not manually breakable, according to the installation
requirements, they must be drilling. To facilitate the operation, they have a centering for the drill bit.

POWER CONNECTION
The installation must include a power line protection device. To the mains line, a bipolar disconnecting
switch dedicated for the gas detection system. The device, clearly identified, must act only on Phase
and Neutral, but not on the Earth. It is advisable to also provide for a surge protector, lightning etc.
Mains Power Supply (90÷264Vdc / 47÷63Hz) should be connected to terminal L, N and Earth at the
right of the housing base. The terminal has a protective fuse (5x20) 2A.
The two 12V/1.3Ah Lead batteries if required should be connected in series to BAT+ (Red) and BAT-
(Black) terminals. For the series connection, use the black cable supplied with two terminals (4.8 mm
Fastens).
The auxiliary input (AUX) can be used to connect devices with a NO or NC contact (gas sensors with
relay contacts, smoke sensors, buttons, etc.). It can be configured to activate one of the available
relays. It can be connected to multiple devices if it’s are homogeneous. (If the device has an NC
contact must be connected in series or in parallel if it’s have all a contact NO).

CONNECTION WITH GAS DETECTORS
Please efe also to the specifics
Use ’s Manuals enclosed with the Gas
Detecto s and the Remote Units.
Please note, that the CE424 has a board with 4 inputs and a board with 4 outputs. n Central
can be installed, a board ES404 and ES414 to have a total of 8 inputs and 9 outputs. The
diagrams, for simplicity, show all the 8 detectors and all relays outputs.
Detectors connection, (f om 1 to 8) with three-wire 4÷20mA transmitters, should be performed on the
inputs board, mounted in the base, on the left. The input terminals, “+, - and “S” should be connected
to the corresponding terminals of the sensor.
The connection of the other detectors (9-24) should be carried out into Remote Unit (please, see the
specific instructions).
The connection wire section between the CE424 and the
sensors should be suitable to the distance, as shown in the
table. The connection needs a shielded cable. (Cables for
control and signaling with shielding copper braid). Shield
should be connected only to the central unit side, and on an
only point of EARTH that has to be equipotential.
The connection to the internal outputs (elays 1 to 9) should be performed on the outputs board,
mounted in the base, on the right. The relay output 9 is located on the central board, see Figure 3 The
nominal load of relay is 250 VAC - 2 A or 30 VDC – 2 A (resistive load).
The relay have changeover free voltage contacts, on the boards, indications NA means NO (Normally
Open), NC (Normally Closed), C (Common), refer to the relays in the normal position (not powered). If an
output is configured as POSITIVE LOGIC, the NO contact will become NC and NC will become NA.
The connection of the other outputs ( elays 10÷25) should be carried out into Remote Unit (please,
see the specific instructions).

EXPANSION BOARD ES4 5 – MODBUS
The connection to a monitoring system via Modbus RTU binary protocol (COM3) is carried on the
optional expansion board ES415 (PC-Card Modbus output).
The ES415 board is mounted on the main board, placed in housing cover. (See Figure 6). Pay
attention, to put the terminals into the connector on the motherboard, making the first, matching the
three click columns with the corresponding holes and then pressing to insert them.
The "H3 (D1)", "GND (Common)," and "L3 (D0)" terminals of the RS485 serial port (COM3) are to be
connected to the supervision system (Master) or dedicated isolated converter (not included).
On standard MODBUS system, all devices are connected (in parallel) on a distribution cable with 3
shielded wires. Two form a balanced pair of twisted conductors, on which the bidirectional data,
typically at 9600 bits per second are transmitted. The third conductor (if used) is the common to all of
the bus devices.
To avoid irreversible damage, disconnect the power supply to the control panel, Mains
power and Battery (if presents) before you unplug or re-connect, any expansion card.
