SigmaINX-8

Sigma INX 8 zone input doubling board for Sigma alarm control panels, product code 5003052, suitable for alarm installations requiring zone input doubling on compatible SIGMA panels or on the ZEM-16 zone expansion module.

The Sigma INX 8 is a zone input doubling board for SIGMA alarm control panels. It is used when additional zone inputs are required, without using external EOL terminal resistors. The front lower terminal block corresponds to 2.2kOhm zones, while the rear higher terminal block corresponds to the doubled zones with 3.3kOhm value.

Technical description

The INX 8 board is fitted to the zone input terminal block of the control panel and allows zone input doubling through different zone value allocation. The front lower terminal block is used for the basic zones, while the rear higher terminal block is used for the doubled zones. The central terminals of the rear block are used for zone COM, while detector power is taken from the corresponding power output on the front terminal block.

Typical applications

Suitable for residential and professional alarm systems, installations requiring more zones, Sigma control panels, ZEM-16 expansions, shops, offices, warehouses and sites requiring zone input doubling without replacing the main alarm panel.

Compatibility note

The INX 8 is a zone doubling board and does not operate as a standalone alarm control panel. Before installation, compatibility with the specific SIGMA panel, correct zone allocation, wiring, ALL DAY SECURE operation where used and proper panel programming must be verified. For high-security installations, cable protection requirements must be carefully evaluated.
