2.0 PRODUCT OVERVIEW
The Impulse Releasing Interface (P/N 70-290) is designed to provide an interface between the supervised
releasing circuit(s) of a non Fike releasing panel (approved for suppression releasing service) and Fike’s
Impulse Valve Operator (IVO). The IVO is the mechanism that is used to release the fire suppressant agent
from a Fike impulse valve container.
The IRI comes pre-assembled from the factory and includes all of the components shown in Exhibit 1 below.
Enclosure Dimensions: 240 mm W x 160 mm H x 90 mm D
Enclosure IP Rating: IP65
2.1 RELEASING CIRCUIT LIMITATIONS
The total number of IRI modules that can be connected to the host control panel’s releasing circuit varies
depending upon the voltage supplied by the control panel to the releasing circuit. Exhibit 2 below shows the
maximum number of IRI modules that can be connected to the circuit based on the supplied panel voltage.
Number of IRI Minimum Circuit Voltage
1 17.8 VDC
2 18.8 VDC
3 19.8 VDC
4 20.8 VDC

2.2 IRI CIRCUIT BOARD SPECIFICATIONS
Power Input (Vdc): 17.8 V to 30 V
Current Consumption: +24V Supervisory
22.0 mA (during capacitor charging, 60 sec. or less)
2.0 mA (after capacitor is charged)
-24V Activated:
57.0 mA (both LEDs active)
Temperature: 0°C to 54.4°C, 93% maximum humidity
Module Wiring: All IRI connections (P1 and P2) are supervised and power-limited.
Compatible Actuation Devices: 02-12728, Impulse Valve Operator (IVO)
3.0 OPERATION
The IRI circuit board utilizes the 24 VDC current supplied by the host control panel to charge the two
capacitors on the IRI. Upon activation of the panel’s releasing circuit, the relays on the IRI module transfer
causing the stored energy in the capacitors to be released to the Impulse Valve Operator; thus activating the
suppression system valve.
Ground fault detection for the IRI module is performed by the releasing circuit connection to the host control
panel (if applicable). The IRI module supervises the Impulse Valve Operator wiring for opens and shorts.
3.1 MODULE LEDs
The IRI is equipped with a red and yellow LED. The red LED, when illuminated, provides positive indication
that the IRI is in the active (discharge) state or that the field wiring has been installed incorrectly (polarity
reversal). The yellow LED, when illuminated, provides indication of an open or short on the IVO circuit.

4.0 MOUNTING
The IRI should not be installed until the installation of the associated detection and control system and
suppression system has been completed and both are ready for testing. The IRI enclosure should be
mounted on a dry, flat, vibration free surface. It should be mounted in an accessible location near the
suppression container it serves.
To install the enclosure, follow these steps:
ICAUTION
The IRI circuit board contains static sensitive components.
Handle the electronics by the edges only and avoid touching the
integrated components. Always ground yourself with a proper
wrist strap before handling the module(s). If the installer is
properly grounded at all times, damage due to static discharge
will not occur. If the module requires repair or return to Fike, it
must be shipped in an anti-static bag.
1. Remove the IRI enclosure cover.
2. Mount the IRI enclosure to the wall with suitable anchors using the pre-drilled mounting holes, as shown
in Exhibit 4.

5.0 WIRING
The IRI circuit board is pre-wired to the termination block provided, as shown in Exhibit 5. No field
connections are to be made to the IRI card. All connections for field wiring shall be made to the wire
termination block provided on the IRI mounting plate. The terminals are capable of accepting wires of up to
2.5 mm2CSA.
LNote: All field wiring shall be completed with the host control panel powered down.
To wire the IRI, follow these steps:
1. Pull field wiring into the enclosure using the cable gland connections provided in the top and bottom of
the enclosure (6 total).
2. Clear the enclosure of all debris before proceeding to the next step.
3. Connect field wiring to the wire termination block, as shown in Exhibit 5, paying close attention to correct
wiring polarity.

aWARNING
Before proceeding to the next step, make sure that the IVO’s are
NOT connected to the suppression containers.
4. Apply power to the host releasing panel. With power applied, both the red and yellow LEDs on the IRM
should NOT illuminated. If the yellow Trouble LED is illuminated, check for an open or short on the IVO
circuit, or if the releasing panel is in Trouble, check for an open or short condition on the EXT OUT
wiring. If the red Active LED is illuminated, check for proper wiring polarity between the releasing circuit
and the IRI. Correct all problems before proceeding.
aWARNING
If the red LED on the IRI is illuminated after power is applied to
the releasing panel, do NOT attempt to connect the IVO to the
suppression container. This may cause accidental release of the
suppression agent.
5. Perform acceptance testing.
6.0 ACCEPTANCE TESTING
Testing of the system should only be carried out by trained personnel and must be done with all IVO’s
disconnected from the suppression containers to ensure that accidental discharge of the extinguishant agent
is avoided.
1. Prior to commencing testing, ensure that the panel is clear of any troubles and the red and yellow LEDs
on each IRI card are not illuminated.
2. Temporarily disconnect the Impulse Valve Operator wires (Red and Black) from the field wiring terminal
strip and verify that the yellow trouble LED on the IRI card illuminates and that a trouble signal is received
by the host releasing control panel.
3. Temporarily remove the releasing circuit end-of-line from field wiring terminal on the last IRI or disconnect
the return wire leg on the last IRI and verify that a Trouble signal is received by the host control panel.
4. Using either a Manual Release or the detection method of the releasing panel, initiate the Release mode.
5. Verify that the red LED on the IRI illuminates and the piston on the Impulse Valve Operator extends,
indicating IVO activation.
6. Reset the host control panel and verify that the red LED on IRI goes out.
7. Reset the Impulse Valve Operator as detailed on the Impulse Valve component sheet, P/N 06-540-1-9.
8. Verify that the host control panel does not activate the IRI during any state other than Release.

7.0 ARMING/DISARMING THE SYSTEM
aWARNING
If there are ground faults present on the host releasing system
(control panel), do NOT connect the Impulse Valve Operator to
the suppression container. Doing so could result in accidental
agent discharge.
To Arm the system:
1. After the system has been fully tested and restored to Normal operation, make sure each IVO has been
reset (piston retracted). Refer to the instructions provided on the Impulse Valve Operator component
sheet, P/N 06-540-1-9.
aWARNING
The IVO must be reset after a system discharge and
container refill. Do not attempt to connect the IVO to the
container with the actuator pin in the extended (fired)
position.
2. Connect the Impulse Valve Operator to the suppression container as detailed on the Impulse Valve
Operator component sheet, P/N 06-540-1-9.
LNote: A discharge pressure switch (P/N 02-9635) must be installed on the discharge piping for
each IVO container equipped with a manual release actuator (required by LPCB).
To Disarm the system:
1. Disconnect the Impulse Valve Operator from the suppression container as detailed on the Impulse Valve
Operator component sheet, P/N 06-540-1-9.
