19.23 SIGNAL CABLE 3m - SIGC3
This cable is provided with 3 minifit connectors to match the corresponding C1, C2 and C3 sockets
on the back plate of the unit. It is used to bring alarm signal out from the unit to an external user and
to give some input signals to C1010 (door open, fire/smoke alarm) from external devices provided
by the installer. This cable is available as option, with 3m standard length. There are no relevant
limits on maximum length admitted. (see previous page)
19.24 LAN DOUBLER FOR SEQUENCING NET (MORE THAN 2 UNITS) - SPLITTER
SPLITTER is a LAN doubler, with 1 male connector (unit side) and 2 female connectors (sequencing
cables side). Its connectors are compatible with ACTSEQC2 (option).
This accessory is useful for connecting more than 2 units in sequencing, when they are equipped
with C1010 electronic board. It has to be connected to the master/slave connector on the unit and
to the two sequencing cables coming from the previous and following units of sequencing net.
Therefore, the necessary number of doublers is = N-2, where N is the number of units in sequencing.
ONLY FOR UNITS WITH MECHANICAL CONTROL (TRA)
19.25 HIGH TEMPERATURE ALARM DEVICE - TMC
With units controlled by C1010 high temperature alarm is already included in microprocessor
functions. This alarm can be available also in case of mechanically controlled units, adding TMC
option. It consists in a thermostat with bi-metallic sensor element for switching signal transmitters.
The adjustment range is from 0°C to 60°C, contacts 6A-250VAC. Type of contacts NC.
19.26 CLOGGED FILTER ALARM DEVICE - RFS
With units controlled by C1010, this differential pressure switch is already included in the standard
configuration. It is supplied as an option for units controlled by mechanical thermostat. For its
description, see chapter 11: Control, Monitoring and Safety components.
19.27 AIRFLOW ALARM DEVICE - FL
When units have C1010 controller and emergency DC evaporator fans, the airflow alarm is provided
directly by the controller, which receives a tachometric signal from the fans. When evaporator fans
are of the AC type, this signal is not available. In this case, the airflow signal is obtained by a
differential pressure switch like the one used for RFS. When the pressure difference between
intake and discharge of fans is lower than the rated value, this device gives the signal of airflow
alarm. This device is already included in units with AC fans controlled by C1010. Instead, with units
controlled by mechanical thermostat TRA, this device is available as an option.
