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 Solenoid must not be connected to the suppression
container.
1.
Temporarily disconnect the solenoid valve wires from the SRM and verify that a fault signal is
received by the SRP panel.
2.
Temporarily switch off the end-of-line switch from the last SRM or disconnect the last SRM and
verify that a fault signal is received by the SRP panel.
3.
Temporarily remove the end of line (EOL) resistor across the Solenoid 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 Solenoid 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 SRM Release LED illuminates and the solenoid valve operates.
7.
Reset the SRP panel and verify that the SRM Release LED turns off.
8.
Using either a manual release or the detection method of the panel, initiate the release mode.
9.
Verify the SRM Release LED illuminates and the solenoid valve operates.
10.
Reset the SRP panel and verify that the SRM Release LED turns off.
11.
Verify that the SRM does not activate during any state other than Release for the programmed
Zone.
12.
Secure the SRM front cover plate to the back box using the screws provided, as shown in
Figure 1 above. Make sure wiring is not pinched or excessive strain is not placed on the SRM
terminal block.
