Control and indicating equipment

Control and Indicating Equipment (CIE) is a component of a fire detection and alarm system through which other components may be connected to it such as detectors, manual call points, sounders, routing equipment, voice alarm equipment and fire protection equipment. It is supplied with power from power supply equipment which may be housed within the CIE enclosure or a separate enclosure.

 

CIE is used to receive and send out signals that are related to fire. CIE also monitors the system for faults (short and open circuit or power supply faults) and indicates the status of the fire detection and alarm system.

CIE designed to meet a European standard such as EN 54-2 or international standard such as ISO 7240-2 has certain options with requirements. For example, it may be designed to provide a signal to fire protection equipment or have dependencies on more than one alarm signal. Some CIEs have other functions which are not specified in the standard. These additional features are normally assessed such that they do not jeopardise compliance.

The choice of CIE is dependent on the specific applications as recommended in the application guidelines for a specific job or building.

Some CIEs have associated repeaters or mimic panels. These are normally used to repeat the indications given on the main CIE and sometimes they have control functions such as silencing sounders. There are no published standards that these repeaters or mimics can be tested against.

Voice Alarm Control and Indicating Equipment (VACIE) is a component of the fire alarm system which receives signals from the CIE or via manual control in order to activate messages via loudspeakers. VACIE may also include emergency microphone to broadcast live messages. The approval processes for this type of equipment is outlined in scheme document SD040.

LPCB approves and lists Control and Indicating Equipment, Voice Alarm Control and Indicating Equipment and power supply equipment approved for use in fire detection and fire alarm systems in buildings. Repeaters or mimics that are listed are only approved with their associated CIE and are subjected to the same environmental tests as the CIE. The approval processes for this type of equipment is outlined in scheme document SD040.
