The LF-CP Series Fire Alarm Control Panel is manufactured based on advanced technology while maintaining high quality during assembly. It is of solid state circuitry and is designed and tested to meet the requirements of industrial or commercial applications. Up to 30 devices, combination of smoke, heat and manual call points, can be connected to a single zone. Any alarm coming from a zone would activate the sounder circuits, common alarm relay, zone relay and the panel audible circuit. Once the panel has been silenced and a subsequent alarm occurs in another zone, the internal speaker and sounder circuits would then re-activate with its associated zone relay.
