What is a fire alarm repeater panel?
A fire alarm repeater panel brings information from the main fire alarm system to a second location, such as a staffed reception or security desk. Depending on the model and system configuration, it can display alarm and fault information and may let authorised users operate selected controls.
Active, passive and mimic panels
- Active repeater: shows system information and offers selected controls. The available functions depend on the model, configuration and access level.
- Passive repeater: provides indication only. Check which events and locations it can display.
- Mimic panel: uses a diagram or plan with indicators to show where events are reported. Check the specified functions before selecting one.
When is a repeater panel useful?
A repeater can give staff access to fire alarm information at another entrance or a staffed point when the main panel is elsewhere. Decide where indication and control are needed as part of the building’s fire alarm design. The location, information shown and controls available should support the building’s response procedures.
Which repeater works with my fire alarm panel?
Start with the exact main panel model and its software version. Check the repeater part number, network type, power supply and available controls against the manufacturer’s documentation before ordering.
- Kentec Sigma CP-R conventional repeater. Kentec specifies Sigma CP control panels with operating software V2.0 or later. Choose the required zone count and the mains-powered K or 24 V DC E version specified for the system.
- Advanced MxPro 5 remote terminals. The Advanced remote display datasheet identifies the MX-5010 for the standard network and MX-5010/FT for the fault-tolerant network. Both are 24 V DC remote display terminals for the MxPro 5 range. Check the exact terminal variant and functions required.
What cable does a fire alarm repeater need?
Cable selection depends on the role of the repeater in the design and the equipment’s installation instructions. For example, Kentec’s Sigma CP-R manual shows a two-core RS-485 data connection for the mains-powered K version and specifies how the cable screen is bonded. The 24 V DC E version also needs a suitable 24 V supply. The number of cores describes the connection. Have the system designer confirm the required fire resistance, cable route, screen termination and power arrangements for the actual installation.
Which standards apply?
BS 5839-1:2025 is the UK code of practice for fire detection and fire alarm systems in non-domestic premises. BS EN 54-2 covers requirements for control and indicating equipment. Check the manufacturer’s declarations for the exact equipment and the design requirements for the site, including how loss of the repeater link is indicated.
