Remote Management System
A.
Overview
The document highlights the methodology to follow to successfully implement and test the SAM- RMS system.
The Acceptance test procedure relies on three key processes; Partial Acceptance - (Physical Acceptance Check & Site
System Acceptance check, as well as Quality Assurance), Network Operation Centre (NOC) functionality test; reliable
data harvesting.
B.
Pre installation requirement
i.
ii.
iii.
iv.
C.
Initial site survey would be done, to determine feasibility for installation.
Sites with any battery issues, such as no backup, should be installed but Hybrid (battery mode) disabled.
Sites with generator problems, such as no remote control capabilities or faults, should be installed but
maintenance & Field Service Engineer informed.
Generators need to have the minimum capabilities such as Remote Start/Stop, Fault/Alarm and Run indications
before the generator can be controlled.

D.
Physical Site Installation Quality
The Physical Site Installation Quality definition:
Main Controller Unit
The installer should ensure that the RMS Unit is powered from the consolidated battery bank, important to note, that at no
point can a RMS be powered from a DC – DC converter.
Step by Step
i. Route the 1.5mm Red/Black twin flex power cable from the RM-System to the consolidated battery backup
ii. Ensure the power cable is in protective conduit pipes and cable should at no point be spliced / joined
iii. Insert the power cable to the back off the RMS as depicted in image below
iv. Connect the power cable through a 5 – 15A DC breaker , which is in turn connected to the DC distribution of the
consolidated battery backup

Alarm Validation Test
i.
The functionality test between site and server is done through testing by activating / clearing alarm conditions on
site and verifying these conditions on the server end.
The NOC engineers will test and validate results as seen by the FSE or installer on site
The NOC engineer should also be able to preform the following test remotely

Start / Stop Generator remote (Hybrid Activated Sites)

Reset Generator Service run time

Start Aircon 1

Start Aircon 2

Swap between Aircons

Reset Aircon Service run time
