The IFP-300ECS (red) and IFP-300ECSB (black) are Intelligent analog/addressable fire alarm control panels (FACP) combined with an Emergency Communication System (ECS) and are direct replacements for the IFP-100ECS FACP. When the ECS features are enabled, they are integrated with the fire alarm and voice evacuation functions of the control panel. The IFP-300ECS panel and accessories provide features to meet the requirements for Mass Notification Systems as described in UL 2572. This state of the art fire alarm control panel allows you to choose one of three SLC protocols per system. The IFP-300ECS panel contains one builtin signaling line circuit (SLC), which can support 159 System Sensor IDP/SK sensors and 159 IDP/SK modules or 127 (SD) Hochiki devices per loop. Additional SLC loops can be added using the model 6815 SLC expander for IDP/SK devices to increase the overall point capacity to a maximum of 300 points per panel, or model 5815XL SLC Expander for SD devices to increase the overall point capacity to a maximum of 254 points per panel.
