No. Part #429853 is a Mechanical ANSUL AUTOMAN Regulated Release Shipping Assembly, not a regulator used to connect a second tank. The second tank typically uses a Regulated Actuator such as part #429850.

is the Ansul system mechanically or electrically operated

The Ansul R-102 system is primarily mechanically operated. It uses a steel cable under tension with fusible links that melt in a fire, releasing the cable tension and activating the system. There is also at least one mechanical pull station that does not require electricity. While some systems may use solenoid electric gas valves, these valves are powered open and will close on power failure, requiring manual reset to reopen.

I would like to replace the rubber nozzle caps with metal caps. Do i need to shut the system down before replacing?
