IRIS8 Loop Extension

IRIS8 Ext. is an analogue addressable fire alarm loop extension. It extends the capacity of IRIS8 panel with 4 more loop controllers. IRIS8 Ext. supports two communication protocols: System Sensor series 200/500 (Loop SS) and Teletek Electronics (Loop TTE) according the type of used devices. In the configuration of the IRIS8 panel can be implemented both Loops SS and TTE at the same time. To avoid or significantly diminish problems when mounting the system it must be carefully planned prior to installation. This includes: establishing an address for every device and planning a name of maximum 40 digits (including the spaces) for each address, thereby ensuring easy access to the device. According to
the acting standards for establishing fire systems and the plan of the building, the devices must be grouped in zones.

BOSEC certified.
