Each Sensor can be configured in two ways quickly and easily:
Preconfigured Setup: Here you can choose one of the models of our production, (See list in Table 1),
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.
Modifications of the other values are however allowed.
Generic Configuration: Here you can configure any type of sensor (compatible or a new model not
yet listed), manually entering all parameters.
Fig.2 - Eg installation with TS282 series detectors.
Each Sensor is protected 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 Sensor may be associated with a ZONE:
The sensors can be grouped into Zones (Max No.2), which can associate up to No.2 relay outputs
different for each alarm level and No.1 for the FAULT.
Each ZONE can be set according to operating LOGIC:
The logic used are the typical logic functions (OR, AND), management of adjacent sensors
(CORR.CON, CIRC.CON). Note that PARK-ITA is a function only for Italy standard (Italian Ministerial Decree DM
01/02/1986 replaced by DM 08/03/2015 and subsequent updates).
The Unit can manage up to No.5, or No.9 Alarm relays:
Each sensor has three alarm levels (Threshold 1, Threshold 2 and Threshold 3) and a FAULT,
freely addressable to any relay output. The control unit has no.5 relay already installed, which can be
increased to No.9 with the expansion card ES414.
The alarm thresholds can be configured with special mode of operation:
For use in car parking "PARKING EN" (EN 50545-1) or to the workplace, such as exposure limit value
TLV.
Each output (relay) can be configured 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 from 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
- Hysteresis ON: is the delay, adjustable from 0 to 300 seconds, of the relay, associated with an alarm
threshold.
- Hysteresis OFF: is the delay, adjustable from 0 to 300 seconds, of the relay to return to normal condition,
when it ends the alarm.
- Time ON: is adjustable from 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.

- Memorized: 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 Control Unit has 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.
The Control Unit can store the Events:
The system can store up to 100 events comprising Alarms, Faults, Power ON, Mains blackout and
Resetting, that can be re-called at any time.
The Control Unit has an SD-CARD slot, it can be used for:
Future updates of the Control Unit firmware.
The Control Unit is protected by 3 LEVELS of PASSWORD:
Some menus are accessible up to three password levels, with a code composed of 4 numbers. The
levels are for access to functions, used by the respective authorized persons:
LEVEL 1: for the User
LEVEL 2: for the Installer or Maintenance technician.
LEVEL 3: Reserved - Only accessible for factory settings.

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 4. While the details of the connections to the sensors and the other
outputs are illustrated in Figure 5.
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 UNIT,MAINS POWER AND BATTERY (IF PRESENTS)DURING INSTALLATION
(WIRING CABLES)OR BEFORE YOU INSTALL ANY EXPANSION BOARDS OR UNPLUG OR RE-
CONNECT THE FLAT CABLE.
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 cable 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 12V/1.3Ah Lead batteries connected
in series (Fig.5) to assure the system powering in case of mains blackout.
The battery life is about 20 minutes with No.8 sensors, but each detector in less increases the
autonomy of about 4 min.
(The batteries are not included in the delivery, but are available on request). If required, to
increase the autonomy, No.2 12V, 3Ah or 7Ah batteries connected in series can be used,
but due to their size, they must be installed outside the control unit.
Considering that each detector absorbs 0.08A/h from the battery, the autonomy, with 8
detectors, becomes: about 4 hours with 3Ah batteries (each sensor less increases the
autonomy by about 30 min) and about 8 hours with 7Ah (each sensor less increases the
autonomy of about 60 minutes).
CABLE GLANDS: the lower side of the housing has 13 inputs designed for metric cable glands (ISO
pitch 1.5 mm). No.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.
Please, pay attention not touch the tip of the internal circuits or the power supply cables
To guarantee the degree of protection of the enclosure, it is recommended to use cable glands with
protection IP55 or higher.

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, Nand Earth at the
right of the housing base. The terminal has a protective fuse (5x20) 2A.
The two 12V/1.3Ah Lead internal 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).
Output Relay No.9 has the same characteristics and use of those described on the next page.

IMPORTANT ADVICE: before installing and configuring the control unit,
evaluate how many alarm devices are connected to the relays to determine how
many relays are needed and how they should act. Please see in SENSORS>
Configure> Description of the items related to the relay outputs.
Please note that the unit has No.5 outputs (relays) that can be increased by installing the
ES414 expansion board to have a total of 9 outputs. The diagrams, for simplicity, show all
relays outputs.
The connection to the internal outputs (relays 1 to 9) should be performed on the outputs board,
mounted in the base, on the right. The relay output no.9 is located on the central board, see Figure 5.
The relays nominal load is 250 VAC - 2 A or 30 VDC –2 A (resistive load).
NOTE: in Italian the indication NA means NO (Normally Open) while the others are the same.
The relay have changeover free voltage contacts, on the boards, the indications 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.
TO AVOID IRREVERSIBLE DAMAGE,DISCONNECT THE POWER SUPPLY TO THE
CONTROL UNIT,MAINS POWER AND BATTERY (IF PRESENTS)BEFORE YOU UNPLUG
OR RE-CONNECT,ANY EXPANSION CARD.

IMPORTANT: Before starting the setup, decide how many and which outputs are
to be used (relay) according to the type, to the requested operation and the
number of actuators installed and in which the alarm levels are associated.
CONFIGURE SENSORS (Level 2):
here are two ways to configure a sensor, but both can be configured
only of our production models (TABLES List detectors PRECONFIGURED)
that have some parameters not editable and others already preset, but it
all changed, must be entered only the outputs (relay number) you
want to activate.
The first way allows you to select, manually, one at a time sensor,
including ones that are preconfigured.
The second way allows you can manually enter all the parameters,
which are freely editable. This allows you to use compatible products
but not of our production or new models not yet included in the list of
pre-configured ones.
For safety, it is not allowed to set outputs separately. They can only be configured in
CONFIGURE or MODIFY a Sensor, a Logic Input or a Zone.
CONFIGURE - PRECONFIGURED SENSOR:
To start the configuration press
ENTER
on the relevant highlighted item.
With

you can choose the number of
the sensor to be configured.
For safety, if you choose a previously configured sensor,
the screen that warns of the possible error, with you can
confirm with
ENTER
and continue, configuring it as if it were a
new sensor, instead of pressing
ESC
will cancel the
operation and you can choose another sensor.
The configuration of a dual sensor (TS255), uses 2 consecutive sensors (1-2, 3-4, or 2-3,
4-5 etc.) You should always start from the first configuration of the two.
Next, you can choose the model code.
To choose the desired one, its structure must be followed as described
below, first the first 2 letters must be chosen, then the 3 numbers and
then the other letters (if present) until the complete code of the model is
composed.
CODE STRUCTURE: our codes are made up of 2 letters that identify the type of product (e.g.
TS = signal transmitter), 3 numbers that identify some functional characteristics, (e.g. TS2xx =
mA signal output), other 2 or more letters specify the type of sensing element used and the
gas detected, e.g. TS282KM (K=catalytic and M = Methane), other letters or numbers, if
present, indicate other specific characteristics of the product.
With
and
you can scroll between the groups of letters and
numbers that make up the model, with
