EV570 is a accessory for the beam smoke detectors RK60, RK70, RK80.
Its functions are extremely important and useful.
When connected electrically with one of these detectors, it allows:
- the measure of the analog signal of the detector
- the remote sensitivity regulation
- he optical indication of the state of prealarm
The instrument is useful to control from distance (up to over 1 Km) a beam detector. On the frontal surface is installed a bar scale is drawn 0 – 10 V for the measure of the signal level, a trimmer for the regulation from distance of the sensitivity and a LED for the optic indication of the state of preallarm and automatic request of maintenace of the detector.
And’ necessary an EV570 for every linear detector, is not possible to check more detectors with an alone EV570.
This accessorius is extremely important and it is advised especially in the fire detection systems of great dimensions where many linear detectors are also employed with large distances by the control unit. When the installation is finished and, if these devices have been installed gathered in an only environment (for instance beside the alarm contromunit), it is possible, the total, centralized and selective control of all the linear detectors fom distance and from an single place.
