4.3. iRIS8 B and iRIS8 S Outputs Control Module (OUT1)
The Outputs Control module OUT1 in iRIS8 B and iRIS8 S addressable fire alarm panels is a structure of two PCBs
mounted to each other via interface slot: Monitored outputs PCB and Programmable Relays PCB.
ATTENTION: The Outputs Control Module OUT1 could not work independently!
4.3.1 OUT1 Elements Description
1 - Monitored Outputs PCB. The PCB is under the Relays
PCB. The elements are indicated with blue numbers.
2 - Jumper for enable/disable indication for earth fault (EFlt).
For example, if you want to enable the earth fault indication set
a jumper.
3 - Monitored Outputs - see the detailed description below.
4 - LED (green) – Indication for data transfer between the main
microprocessor of the panel and the Output Module. In normal
operation mode it is constantly blinking.
5 - Interface connector for connecting the first Loop Expander
Module (on the back side of the Outputs Module).
6 - Ribbon cable interface connector from the main power
suply unit and to the front panel (on the back side of the
Outputs Module).
7 – Relays PCB. The elements are indicated with black
numbers.
8 - Programmable volt free switching over relay contacts - see
the detailed description below.
9 - Specialized inputs for extinguishing - see the detailed
description below.
Monitored outputs terminals:
DC Auxiliary output, 20 VA @ 0.3A
Monitored output for connecting of a sounder, 24V DC/1A
Monitored output for connecting of auxiliary devices, 24V DC/0.1A.
This output is deactivated in case of system trouble or fault.
Monitored outputs for connecting of auxiliary devices (e.g., signaling devices), 24V DC/0.1A.
These outputs are activated in case of a fire alarm condition.
ATTENTION: The total current consumption of outputs +24V, SND, FIRE R, FIRE P and FAULT R must not
exceed 0.5A!
The output SND at activation, provides 24VDC@1A to the load, and outputs FAULT R, FIRE R and FIRE P, at
activation, provide 24VDC@0.1A to the load. It is necessary to connect in parallel to the last device in the loop a 10k
terminate resistor, so to ensure that the panel is able to detect any break or short circuit in the loop - see item 4.3.2 and
item 4.3.3.
Programmable relay terminals:
Programmable volt free switching over relay contacts each, 10A@24VDC.
Each relay has one NO (normal open) and one NC (normal closed) contact
with common lead on a terminal. When a relay output is activated the NO
contact is closed and the NC contact is opened.
Protection Confirmation - Input for monitoring of signal “Confirmation for extinguishing started in the
site” sent by extinguishing control panel.
Fault Protection - Input for monitoring of signal “Fault” sent by extinguishing control panel.
Alarm Confirmation - Input for monitoring of signal “Alarm confirmation” sent by extinguishing
control panel.
Protection Confirmation passive output according the requirements of VdS 2540.
