Apollo's premium AlarmSense range features high-quality detectors, sounders, and call points designed specifically for bi-wire fire alarm systems. We offer a selection of compatible fire alarm panels that fully support the AlarmSense technology. For your convenience, we also provide complete pre-built AlarmSense fire alarm systems that include panels, detectors, sounders, and call points - everything you need for a reliable fire safety solution.
AlarmSense devices share a single zone circuit for both detectors and sounders.
This removes the need for separate sounder circuits in many installations, reducing labour time and simplifying first fix. It is still a conventional zoned system, not addressable.
No. All devices on an AlarmSense zone must be AlarmSense compatible. Series 65, XP95 or Discovery devices are not compatible on the same circuit.
You must use a panel specifically designed to support AlarmSense bi-wire technology. Standard conventional panels without AlarmSense compatibility will not operate the devices correctly. Always confirm the panel’s compatibility before installation. We stock a range of Apollo AlarmSense control panels.
When correctly designed, installed and commissioned, AlarmSense systems can comply with BS 5839-1.
System design must follow standard zoning, sound pressure level and coverage requirements.
AlarmSense is commonly specified for:
Small to medium commercial premises
Schools and care facilities
HMOs and low-rise residential blocks
Offices and retail units
It is often selected where a conventional zoned system is suitable but reduced wiring is preferred.
No. AlarmSense is a two-wire/bi-wire conventional system. It does not provide individual device addressing or pinpoint identification like addressable systems.
