Single Zone Interface Unit Type:ZI-01 & ZI-01RS

 For use in conjunction with Proline type "TH" digital linear heat sensor cables only.

 Features

• Single zone monitoring - 2,000m (6500ft) Proline type “TH” digital linear heat sensor cable
•                                   OR- 5,000m (16,400ft) Proline type “TH” digital linear heat sensor cable
• Integral “Distance Read” alarm identification meter – tolerance of actual location +/- 0.2%
• Back lit display - Green = Normal, Flashing Green = Fault, Red = Alarm
• Operating current @ 24VDC - 1. 2mA (without back light or RS232)
• Solid-state volt-free contact outputs - Alarm and Fault
• 2 part terminal blocks – for ease of wire connection in restricted locations
• Where necessary, interconnecting cabling can be used – max. 50 ohms
• Polycarbonate enclosure to IP66 rating
• May be powered from Central Fire Alarm Control Panel loop or dedicated 24VDC supply
• ZI-01RS version provides RS232 serial interface

General

The Proline single “zone” OPTIONAL interface unit type ZI-01 provides end user customers with an effective  means of integrating the PROLINE “special hazard” digital linear heat sensing cable system with an existing / proposed Central Fire Alarm Control Panel (manufactured + supplied by others).
The ZI-01 provides (as standard) visual indication of the accurate location of the point of alarm along an associated length of Proline “TH” digital linear heat sensor cable. With the units back lit visual display colour also changing from GREEN to RED when in an alarm state.
FIRE and FAULT output signalling is via solid state volt-free contact outputs, with additional RS232 serial link available with the      ZI-01 RS unit option.

ZI-01 (fig.1) and ZI-01RS (fig.2) line drawings are provided for reference below.

Description

The PROLINE type ZI-01 has been designed as an OPTIONAL low power single zone interface unit for exclusive use in conjunction with up to 2000m / 6500ft of the Proline type “TH” digital linear heat sensor cable range. A 5000m/16,400ft per zone interface version is also available if required.
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 ZI-01 operating supply, due to limitation in available power from the loop.

The LCD display will indicate the abbreviation: “STBY” with a continuous 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 the interface is to be located remote from the risk area installed heat sensing cable .
Under open circuit FAULT conditions on the connected “TH” digital linear heat sensor cable and / or interconnecting cable (where used), the display will change to read “OPEN” and the GREEN back light will flash.

In an alarm state, the back lit 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.  Accuracy of the displayed location is 0.2% or better, plus cable tolerances.
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 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 “CALE” with a flashing green back light as a calibration error signal.
