Addressable technical alarm

Technical alarm panels are used in all types of buildings (boiler rooms, lifts, plant rooms, etc.) to signal technical faults in installations. The input information is normally open or closed potential-free contacts.

The main advantage of this addressable system is :

• Centralise data via input modules to reduce the number of cables and cut installation time.
• Associate names with input contacts to make them easier to read.
• Configure priority contacts. The control unit has four dry contacts. For each input, you can assign a contact that will switch as soon as a fault is detected. The control unit also has a summary dry contact that switches as soon as a general fault occurs.

The control unit, the nerve centre of the installation, manages the power supply to the input modules and communication, and centralises and records all faults detected by the input modules.
A computer can be used to configure the control unit via a USB cable:

• Naming an input contact
• Assign a relay
• Invert the input of a normally open contact

The software used is based on the JAVA environment, which means it can be adapted to all WINDOWS environments. 

The input modulesa " TEST " button signals a fault on all the module's inputs to check that the information is being sent to the control unit. 

The output modules are each fitted with 16 relays, enabling the status of each input on the input modules to be reported. 
A " TEST " button on the card can be used to check the operation of all the relays.
