iRIS4 - Addressable Fire Alarm Panel – Installation Manual
Monitored outputs terminals:
Terminal
Description
+24V
DC Auxiliary output, 24VA@0.3A
GND
Common earth
SND
Monitored output for connecting of a sounder, 24V DC/0.5A
Monitored output for connecting of auxiliary devices, 24V DC/0.1A.
Fault R
This output is deactivated in case of system trouble or fault.
Fire R
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.
Fire P
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@0.5A 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
item 4.2.3.
Programmable relay terminals:
Terminal
Description
Programmable volt free switching over relay contacts each, 15A@24VDC.
Each relay has one NO (normal open) and one NC (normal closed) contact
Rel 1-4
with common lead on a terminal. When a relay output is activated the NO
contact is closed and the NC contact is opened.
4.2.2. Connection of Sounders
To the monitored output SND, could be connected several sounders - Figure 18. The maximum number of sounders
that could be connected in the circuit, depends on their total current consumption, which must not exceed 0.5A.
Before connecting the last sounder in the circuit, parallel to it must be added resistor 10k.
4.2.3. Connection of Signalling Devices
To every monitored output FAULT R, FIRE R and FIRE P could be connected signalling and other control devices –
Figure 19. The maximal consumption of the devices should not exceed 0.1А.
Before connecting the last device in the circuit, parallel to it must be added resistor 10k.
