Description
The QR Systems MK-1 switching module supervises the line to audible and visual fire alarm devices connected to the outputs of the addressable control panel and the KS-02-250 system controller. The module is designed for notification circuits: it is placed in the sounder circuit and lets the panel supervise the line all the way to the device. The 20×10×4 mm body, excluding wires, fits inside the sounder housing or in a junction box. The module takes no address slots, so the panel capacity stays available for detectors. Connection is by wire leads of 0.35 mm² cross-section according to the passport diagram: panel output and a 24 V alarm device.
Advantages
- Supervision of the sounder line — the panel sees the state of the circuit to the audible and visual devices
- Load current up to 1 A at 30 V DC — works with alarm devices of different power
- 20×10×4 mm and up to 3 g — fits inside the sounder housing or a junction box
- 0 address slots — the panel's address capacity stays available for detectors
- Temperature range −25…+55 °C — operation in unheated rooms
- Protection rating IP30 — for installation inside a sounder or a box
Applications
- Sounder and beacon circuits of notification systems in QR Systems installations
- Supervising the line to exit signs and sirens on panel outputs
- Connecting alarm devices to the KS-02-250 controller
- Sites with unheated areas: warehouses, car parks, technical rooms
