Introduction: What the Pyronix EURO‑ZEM8+ Is and Why It Matters
Pyronix EURO‑ZEM8+ (ITM001248)is a compact 8‑zone wired expansion module designed to augment Pyronix EURO control panels and compatible hybrid systems. For professional installers and integrators who need to increase the number of wired inputs without replacing a main panel, the EURO‑ZEM8+ delivers an efficient, cost‑effective solution. Key selling points include eight additional wired inputs (with double‑pole or double EOL options), four programmable transistor (open‑drain) PGM outputs, and an integrated RS‑485 repeater that extends data‑bus reach — all in a small module that fits neatly into retrofit and new‑build installations.
- Adds 8 wired inputs (double‑pole or 3EOL options) to a control panel
- Four transistor/PGM outputs (open‑drain) rated to 1 A continuous
- Integrated RS‑485 repeater (IN/OUT) to extend bus and cable distance
- Low quiescent current (~25 mA) with small PGM LED draw (≈6 mA)
- Compact footprint (173 × 125 × 32 mm) and light weight (0.24 kg)
- Case tamper protection and suitability for PD6662:2010 / EN50131‑1 (system grading applies)
Detailed specifications and benefits
The EURO‑ZEM8+ is engineered to balance function, reliability and installer convenience. Below are the technical specifications and the practical benefits they deliver.
The module provides 8 wired inputs that can be configured for double‑pole wiring or with double EOL/3EOL resistor options. This flexibility accommodates a wide array of wired detectors and peripherals and supports secure wiring practices required by many burglar alarm standards. For installers, that means straightforward integration with door contacts, PIRs, shock sensors and tamper circuits without hardware workarounds.
Four open‑drain transistor outputs (PGMs) are available, each rated to 1 A continuous. These outputs are suitable for triggering external devices such as relays, sirens (via a relay), auxiliary lighting, or system indicators. The relatively robust continuous current rating makes the module useful for controlling low‑power devices directly or driving intermediary switching components in higher‑power circuits.
An onboard RS‑485 repeater helps extend the effective range of the control panel’s data bus. For distributed installations — where sensors, keypads or other modules are spread over longer distances — the repeater mitigates cable length limitations and signal degradation without resorting to third‑party extenders.
The module operates from a 10.5–15 V DC supply and has a low quiescent current of approximately 25 mA. Low standby consumption helps keep overall system current demand down, a meaningful advantage when multiple expanders or peripherals are used on battery‑backed systems.
Measuring 173 × 125 × 32 mm and weighing only 0.24 kg, the EURO‑ZEM8+ is compact enough for retrofit work and tidy new‑build installations. It includes case tamper protection and is designed to be installed in accordance with Pyronix guidance and local regulations. Operating temperature range is −10°C to +40°C, suitable for most indoor installations.
The module is suitable for use in systems designed to PD6662:2010 and EN50131‑1 (system grading depends on the overall configuration).

Use cases and scenarios where the EURO‑ZEM8+ excels
The EURO‑ZEM8+ is especially valuable in scenarios where additional wired inputs or improved bus reach are required without the expense and disruption of swapping out a control panel.
- Large family homes with multiple zones (garage, outbuildings, annexes) often exhaust the base panel’s inputs. Adding the EURO‑ZEM8+ gives installers eight extra wired zones for doors, windows, PIRs and shock sensors.
- Retail outlets, small offices, or modular commercial spaces can use the module to centrally monitor separate rooms, server closets, and perimeter doors without running a new panel at each location.
- The RS‑485 repeater is a standout benefit in distributed systems, allowing longer cable runs and additional nodes without the need for dedicated signal repeaters or complex wiring schemes.
- When upgrading an existing alarm system, customers often want more detection points but don’t want the cost and downtime of panel replacement. The EURO‑ZEM8+ slots into existing EURO systems cleanly, preserving the main panel while expanding capability.
How it compares with similar products
Understanding where the EURO‑ZEM8+ sits in the market helps installers choose the right expander for a job. Important comparison points include zone count, PGM capability, bus extension features and whether a module includes its own power supply.
Smaller expanders (e.g., 4‑zone modules) are sufficient for minor expansions but may force additional modules when more zones are required. Larger expanders (16+ zones) reduce the number of devices but are physically larger, more expensive and sometimes over‑specified for the typical residential job. The EURO‑ZEM8+ strikes a middle ground: cost‑effective (suggested retail ~£99), compact and flexible for most common projects.
Some expanders include an integrated PSU and enclosure (such as the EURO‑ZEM8+PSU variant) which simplifies wiring where the remote module needs local power. The bare EURO‑ZEM8+ is ideal when system power is already available at the location or where space constraints preclude a larger PSU enclosure.
Wireless expanders or wireless sensors offer flexibility where wiring is impractical, but they can introduce concerns around battery life, RF interference and incremental maintenance. Wired expanders like the EURO‑ZEM8+ remain preferred for critical zones, permanent installations and where signal reliability and compliance are priorities.
Customer feedback and installer impressions
There are limited public consumer reviews specific to the EURO‑ZEM8+; however, feedback from professional installers and integrators typically highlights a few recurring themes:
- Reliability and compatibility: Installers appreciate that the module integrates smoothly with EURO control panels and maintains stable operation over time.
- Bus extension convenience: The RS‑485 repeater is often cited as a practical feature that saves time and additional hardware when extending installations.
- Simplicity and low power draw: The low quiescent current and modest footprint are frequently noted as advantages for battery‑backed or space‑limited setups.
Representative installer comments (anonymous/pattern observations):
- "A neat way to add multiple zones without changing the panel — saves the customer money and avoids reprogramming complications."
- "The RS‑485 repeater made a distributed shop fit‑out straightforward; we didn’t need separate line drivers."
Conclusion: Why the EURO‑ZEM8+ is a strong choice
The Pyronix EURO‑ZEM8+ is a practical, well‑rounded expander for installers and system designers who need additional wired inputs, flexible PGM outputs and improved bus reach without a major system overhaul. Its combination of eight configurable zones, four 1 A PGM outputs, integrated RS‑485 repeater, and low quiescent current make it particularly suited to residential, small commercial and retrofit projects.
While it’s a bare module (a PSU/enclosure variant exists for power‑hungry or standalone locations) and manufacturer warranty details should be confirmed at point of purchase, the EURO‑ZEM8+ offers a sensible balance of capability, size and affordability. For professionals designing or upgrading Pyronix EURO systems, it’s an asset that reduces installation time, limits disruption and provides the flexibility modern installations demand.
