Alarm Fault
Signals to central fire alarm panel
24Vdc local input supply (18-36 Vdc range) or from central panel loop power Backlit display will be disabled due to the lack of sufficient loop power

FyreLine FM approved & UL listed Linear Heat Sensor Cable (2 conductors)
Description The FyreLine type EF-ZI01 has been designed as an opitional low power single zone interface unit for exclusive use in conjunction with up to 2000m/650ft of the proline type “TH” digital linear heat sensor cable range. The unit can be powered either by the central fire alarm control panel loop (12-36Vdc) or from a dedicated (18-36Vdc) supply. The back light and RS232 option are disabled when using the Central Fire Alarm Control Panel loop to provide the EF-ZI01 operating supply, due to limitation in available power from the loop. The LCD display will indicate the abbreviation: “STBY” with a continous GREEN back light to confirm supply available and normal operating condition status for the interface, its associated type “TH” digital linear heat sensor cable and non heat sensitive inter-connecting cable where used. Under open circuit FAULT conditions the display will change to read “HIGH or OPEN” (depending on the version) and the GREEN back light will flash. In an alarm state, the backlit display will change in colour from GREEN to RED, and visually indicate alternating non-latching “FIRE” and an “xxxx” message (where “xxxx” indicates the location of the alarm along the heat sensor cable in feet or metres). The FIRE signal WILL be latched at the Central Fire Alarm Control Panel to which the interface has been connected. Where non heat sensitive cable is installed (as between the sensor cable protected risk area and remotely installed interface unit) the electrical resistance of any interconnecting cable can be zero offset during site commissioning by way of a single “push button” operation. In the event interconnecting cable is installed in lengths with electrical resistance in excess of the allowed 50 ohms, the LCD display will register “CABLE” with a flashing green back light as a calibration error signal. General
Hazardous Area Use
The FyreLine single “zone” OPTIONAL interface unit type EF-ZI01 provides end user customers with: • Alarm Point Location • Colour coded LCD display • Volt free contact output signalling for fire & fault conditions – with RS232 serial link (model ZI-01RS only) • Ease of Integration with Central Fire Alarm Control and Building Management Panels
EF-ZI01 and EF-ZI01RS interface units MUST be installed within a site designated “SAFE” area – using short term fire-proof interconnecting cable between the interface and hazardous area installed Eexe junction box and “TH” linear heat sensor cable.
