ESP MagDuo 8 Zone Two-Wire Fire Alarm Panel Kit - Black

The ESP MagDuo 8 Zone Fire Alarm Panel Kit is a complete two-wire fire detection system built around the MAGDUO8B black control panel, rated for up to eight addressable zones. The kit includes six MAGDUOSHDS selectable optical smoke/heat detectors with integrated sounders and bases, one MAGDUOSHDSS detector with sounder and strobe, two MAGDUOCP resettable manual call points, and a head removal tool. The control panel requires two 12V 3.2Ah SLA batteries (sold separately) for backup power during mains failure.

Designed for commercial, industrial and multi-occupancy residential buildings requiring BS 5839-compliant fire detection, the two-wire architecture simplifies installation by running detection devices, sounders and power over a single cable pair rather than separate fire and sounder circuits. This reduces wiring costs and installation time in larger buildings. The panel fits a standard wall-mounted enclosure measuring 380mm wide, 350mm high and 240mm deep, and supports conventional or addressable configuration depending on how the detectors are wired.

Each of the six MAGDUOSHDS detectors can be set to optical smoke detection or fixed-temperature heat detection via a selector switch on the detector head, allowing the system to be tailored room-by-room without needing separate detector models. The MAGDUOSHDSS detector adds a high-output strobe for areas requiring visual alarm indication (corridors, high-noise environments, accessibility compliance). The two resettable call points allow manual alarm activation and can be surface-mounted at exit points. The head removal tool allows detectors to be removed for maintenance or testing without damaging the twist-lock base.

The black finish on the control panel and detector heads suits modern interiors and commercial fitouts where white equipment would stand out visually. The panel provides zone indication via LEDs on the front fascia, fault monitoring, and outputs for additional sounders or auxiliary devices. Total kit weight is 5.4kg including packaging.

Product Specification Sheet

Are batteries included in the kit?

No. The MAGDUO8B panel requires two 12V 3.2Ah sealed lead-acid (SLA) batteries for backup power, which are sold separately. The panel will operate on mains power alone during installation and testing, but batteries must be fitted before the system is commissioned to comply with fire safety standards.

What is the difference between the MAGDUOSHDS and MAGDUOSHDSS detectors?

The MAGDUOSHDS is a selectable optical smoke or heat detector with an integrated sounder and base. The MAGDUOSHDSS adds a high-output visual strobe to the sounder, providing visual alarm indication for areas requiring accessibility compliance or where audible alarms may not be heard (high-noise environments, corridors).

Can the detectors be switched between smoke and heat modes after installation?

Yes. Each MAGDUOSHDS and MAGDUOSHDSS detector has a selector switch on the head that allows it to be set to optical smoke detection or fixed-temperature heat detection. The detector must be removed from the base to access the switch, using the included head removal tool.

What cable type is needed for two-wire installation?

Two-wire fire alarm systems typically use fire-rated cable such as FP200 or equivalent, rated to maintain circuit integrity during a fire. The specific cable specification and installation method must comply with BS 5839-1 and local building regulations. Consult a qualified fire alarm installer for system design and cabling requirements.
