Repeater panels are properly described as ‘Repeat Control and Indication Equipment’ and fall into three main types:
- Active: This type of repeater will have full indication of events at the main control panel and will also offer fire system controls (such as silence, reset etc.) from the repeater.
- Passive: This would offer indication of some or all events at the main control panel but have no fire system controls.
- Mimic: This is normally in the form of a printed or engraved plan of the building marked with the fire system detection zones and incorporating illuminated zone indicators to identify any zone in alarm.
An annunciator or repeater panel shows the state of the fire panel. They are required to be installed by the front entry in a lot of jurisdiction’s so the fire department can see where the fire is located without having to go all the way inside the building to look at the fire panel.
- If installation of the main control panel is difficult when located correctly at the main entrance area, then a repeater panel could be used to ensure control facilities are available at the correct location and allowing the control panel to be located elsewhere.
- A control panel mounted in an entrance area in certain types of building may be subject to damage and hence failure of the system. By locating the control panel in a safe location and utilising a repeater panel in the entrance area the integrity of the system is maintained at a higher level and possible future costs to repair potential damage are likely to be lower.
- If a building has a manned security facility as well as a main entrance area then repeater panels may be used to ensure all relevant personnel are informed in the event of fire.
- Where individually protected premises have shared entrance areas it may be necessary to provide additional repeater panels in the shared areas.
