Inputs are optically isolated up to 2000VAC. These Inputs are arranged in groups of four with one common
connection per group. Connectors 1 to 4 are assigned to each Input and the fifth connector is assigned to the
common of theses Inputs.
System can be ordered to accept Dry Contact (voltage free) or Powered (wet) Inputs.
The Inputs’ type and the voltage level should be specified at the time of placing the order. Here are the
available options:
V0: Dry Contact Inputs (The Annunciator feeds 24VDC to input contacts internally)
V1: 24V (AC/DC) Inputs
V2: 48V (AC/DC) Inputs
V3: 90V to 180V (AC/DC) Inputs
V3: 150V to 250V (AC/DC) Inputs
V5: Other Voltages (to be specified)
Each Input can be set individually as Normally Open or Normally Closed via the ALCON software.

Note:
1- It is VERY IMPORTANT to make sure that the Inputs’ type and voltage level are in accordance to the
Annunciator model number and specification. Otherwise, system will be damaged.
2- Improper wiring of inputs will damage the system..
