Description

The QR Systems MK-6 switching module connects ShU-DU smoke exhaust fan control cabinets and other dry-contact-driven equipment to the outputs of QR Systems addressable control panels and monitors their state. The module is used with the addressable analogue fire alarm control panel and integrates fully with the QR Systems range of panels and system controllers. It is powered from a 230 V ±10 % mains supply, and the relay output is rated to switch up to 5 A at mains voltage. On board are one dry-contact output, three inputs for connecting dry contacts and two monitoring outputs through which the panel tracks the state of the actuators. The module takes no address slots; its 60 g weight and 115×93×40 mm dimensions are designed for installation in existing cabinets and boards.

Advantages

Switching up to 5 A at 230 V — direct control of a ShU-DU cabinet without an intermediate relay
3 dry-contact inputs and 2 monitoring outputs — the panel tracks the state of the actuators
0 address slots — the panel capacity stays available for detectors
Current consumption up to 12 mA — minimal load on the mains
60 g and 115×93×40 mm — installation in existing cabinets and boards
Average service life 10 years, mean time between failures 60 000 h — reliability for smoke control systems

Applications

Connecting ShU-DU cabinets of smoke exhaust fans to QR Systems addressable panels
Monitoring the state of fans and other dry-contact equipment
Smoke control systems of shopping malls, business centres and car parks
Building services automation boards at sites with a QR Systems system

Frequently asked questions

How does the MK-6 differ from the other MK series modules?

The MK-6 is powered from 230 V mains and switches up to 5 A, so it controls a ShU-DU cabinet directly. Besides the dry-contact output it has three dry-contact inputs and two monitoring outputs that report the state of the actuators to the panel.

Does the module occupy an address in the system?

No, the number of address slots occupied is 0. The module connects to the outputs of the addressable control panel.

What operating conditions are allowed?

Operating temperature range −10…+55 °C, relative humidity up to 93 % at +40 °C, housing protection rating IP20 — the module is installed inside a cabinet or board.
