The Pyronix EURO‑ZEM8+PSU is an 8‑zone wired input expander with an integrated metal‑cased 2.5 A power supply and RS‑485 repeater. It adds eight wired inputs (double‑pole or double EOL) and four transistor outputs to compatible Pyronix/Euro range alarm panels, and is housed in a tamper‑protected metal enclosure suitable for Grade 3 capable systems when installed as part of a graded system.

• 8 wired inputs — supports double‑pole or double EOL wiring for zone circuits.
• 4 transistor outputs — open‑collector outputs for auxiliary control.
• Integrated power — 2.5 A mains power supply with dedicated battery/bus protection.
• RS‑485 bus repeater — extends data bus range with IN/OUT connections.
• Secure enclosure — metal case with front and rear tamper switches.
• Grade & standards — manual references EN50131 and PD6662 showing Grade 3 capability as part of a compliant system.

Use cases: expands wired zone capacity on Euro/Pyronix control panels in commercial and domestic installations where additional hardwired detectors or contacts are required. Suitable for installation by trained/instructed personnel only — follow the Pyronix installation manual and local regulations. Observe all mains isolation practices when connecting the unit to 230 V AC supply. For detailed wiring, fuse and battery configuration see the official installation manual.
