Central co 2, 3 O 4 Zones with Double Ventilation and Battery Outlet – ZCODVB Cofem

Description

Central co 2, 3 O 4 Zones with Double Ventilation and Battery Outlet – ZCODVB Cofem

Addressable COsensor automatic central with carbon monoxide diffusion sensors (CO) and nitrogen dioxide (NO2) designed according to the European standard EN 50545-1 and UNE certified 23300.

This plant includes the ZafirCO2 models (Ref. ZCO2), ZafirCO3 (Ref. ZCO3) and ZafirCO4 (Ref. ZCO4). They are equivalent to 2, 3 oh 4 zones and capacity up to 25 CO and / or sensors 25 NO2 sensors per zone.

These models support DVB version (Double Ventilation and Batteries).

The central COsensor ZafirCO allows you to configure the activation concentration for the ventilation level 1,2 and alarm, in addition to the activation delay and stop delay times of said levels / alarm.

It has independent dry contact outputs per zone for each ventilation and alarm level, in addition to general fault output and auxiliary power supply 30 Vdc.

The control panel has a maintenance mode that allows you to easily check the operation of the sensors by observing how its LED blinks when faced with the test gas.

The control panel allows you to identify, through the menu, all the sensors of the installation through their programming number. When this identification is not necessary, the auto-configuration function of the control panel will automatically detect all sensors in the zones and show them on the display. Confirming this information, the control unit goes directly into work mode.

The philosophy and mode of operation of the equipment is designed according to the EN standard 50545-1, using diffusion sensors and factory calibration to operate throughout its operational life, and UNE certified 23300.
