AZE 1.2

Accessories KRM-X

Display unit for Modbus duct smoke detectors 24 V and 230 V AC/DC.
For connecting and displaying the operating states
of up to 99 duct smoke detectors, type KRM-2-MOD,
KRM-2-DZ-MOD, KRM-1-MOD, and KRM-1-DZ-MOD. The
display unit shows and evaluates smoke,
contamination, and malfunctions and also monitors
cables for cable breakage and short circuits,
which are shown as plain text on the LCD display
and via LEDs. The message is sent both via
potential-free contacts and via an RS 485
interface for forwarding to the building
automation systems. The current status of each
detector can be queried via a keypad. Frame with
click-in base for installation on mounting rail
in the control cabinet. Dimensions: approx. 160 x
90 x 50 mm (W x H x D) Protection class: IP 20
Ambient temperature: 0 – 50 °C
