Acceptance Testing
Acceptance testing shall be performed in accordance with the requirements of BS7273 Pt1 : 2006,
requirements of the Local Authority Having Jurisdiction (AHJ), and the following requirements:
Note: before carrying out the following tests the impulse operator must not be connected to the
suppression container.
1.
Temporarily disconnect the IVO wires from the IRM and verify that a fault signal is received by
the SRP panel.
2.
Temporarily switch off the end-of-line switch from the last IRM or disconnect the last IRM and
verify that a fault signal is received by the SRP panel.
3.
Temporarily remove the end of line (EOL) resistor across the IVO Missing Input and verify that a
fault signal is received by the SRP panel. Repeat this for Bottle Pressure and Discharge Pressure
Inputs. These faults take approximately 60 seconds to be reported.
4.
Temporarily trigger the IVO Missing Input by connecting a 470Ω or 680Ω resistor across IP+ and
IP- terminals and verify that a fault signal is received by the SRP panel. Repeat this for the Bottle
Pressure Input. These faults take approximately 60 seconds to be reported.
5.
Temporarily trigger the Discharge Pressure Input by connecting a 470Ω or 680Ω resistor across
IP+ and IP- terminals and verify that the system goes into a release state.
6.
Verify the IRM Release LED illuminates and the piston on the Impulse Valve Operator extends.
7.
Reset the SRP panel and verify that the IRM Release LED turns off.
8.
Using either a Manual Release or the detection method of the SRP panel, initiate the Release
mode.
9.
Verify the IRM Release LED illuminates and the piston on the Impulse Valve Operator extends.
10.
Reset the SRP panel and verify that the IRM Release LED turns off.
11.
Reset the Impulse Valve Operator as detailed on the Impulse Valve component sheet,
P/N 06-492.
12.
Verify that the IRM does not activate during any state other than Release for the programmed
Zone.
13.
Secure the IRM front cover plate to the back box using the screws provided, as shown in
Figure 1. Make sure wiring is not pinched or excessive strain is not placed on the IRM terminal
block.
