DF6000 - USER MANUAL

1 Channel I/O device with mains rated switching capability (MIO1240)

MIO1240 is a single channel input / output unit, the output is capable of switching up to 8 A at 230 V ac.

Commonly used for applications such as door release contr

ols and plant shut down signalling the input is

monitored for open and short circuits, a speciﬁc resistance is required to activate an alarm condition, fully

open or short circuit conditions are monitored and generate a system fault signal. The input is suitable for

use as a ﬁre signal input such as from a sprinkler ﬂow switch, however it can also be used to monitor non

ﬁre inputs such as an external keyswitch.

Zone monitor unit (MIU871)

MIU871 is designed to enable a zone of compatible conventional detectors and callpoints to be

connected into the DF6000 loop, it is compatible with up to 20 Menvier conventional detectors

connected via FXN520 bases. Please refer to local standards e.g. BS5839 Pt1:2002 for details of the

maximum allowable area to be covered by a single spur / zone. MIU871 ﬁxes to a standard, deep, double

gang back box and can be either surface or semi recess mounted. When semi recessed only the front

section protrudes giving a maximum 29mm depth.

MIU871/IS

Similar to the above but the detection zone has been programmed to accept a Zener barrier and zone of

intrinsically safe detectors. End of line for this zone now becomes 6K8 and the diode in the detector base

must be removed.
