Drager Regard-1 Control System

The Drager Regard-1 Control System is robust, reliable and very cost effective. The Drager Regard-1 Control System is compact and is a complete standalone and independent system for the control of a single gas detector. The system is suitable for monitors of oxygen, combustible gases, toxic gases and vapours.

High flexibility - The Drager Regard-1 Control System can either be connected to a 4-20-mA transmitter or to Polytron-SE-Ex mV sensing heads. The alarm's current status is displayed via three LEDs. There are three fully configurable alarm relays: rising or falling, latching or non-latching. The LEDs will flash with a new alarm, light up continuously to display an acknowledged and recognised alarm situation or extinguish if there is no alarm. Displayed on the large LC display is the current gas concentration. If a fault occurs or the alarm thresholds are exceeded, the integrated audible alarm will sound. A fault relay is provided to indicate a transmitter or system fault. A separate fault led is provided on the panel which will flash under new fault condition, light continuously under acknowledged fault condition or will be extinguished under normal conditions. When maintenance is carried out, the maintenance or inhibit relay can be used to report this special status via a remote display.

Useful additions - There is an optional TWA control module that the Drager Regard-1 Control System can be equipped with. This module enables the output of a TWA alarm as well as the repeat of a 4 to 20mA signal and the alarm states via a digital interface. To make sure that the Drager Regard-1 Control System can still function during a power failure, two batteries of 1.2 Ah each can be inserted into the integrated battery compartment. This will give an operating time from 30 minutes up to two hours, depending on the transmitter used. The batteries are re-charged by the Drager Regard-1 Control System.

Robust enclosure - The installation of the Drager Regard-1 Control System can be at virtually any location within safe areas, using the robust IP65 enclosure.

Certifications - The Drager Regard-1 Control System is certified to EN 61779-1/4/5 and EN 50104 for explosion monitoring and oxygen measuring, in accordance with the ATEX directive and therefore, also suitable for applications which require the measuring function for explosion protection (primary measure in accordance with EN 1127-1, paragraph 6). The Drager Regard-1 Control System was also tested independently to EN 45544 for the monitoring of toxic gases.
