Siemens FS140 Whole House Surge Protection Device Rated for 140,000 Amps by Siemens

Q: It states there is an audible alarm. Can this be silenced afterwards?

The two-pole breaker this device wires into is technically the audible alarm shutoff. The FirstSurge device is typically wired into a dedicated 2 pole breaker. So when you hear the alarm, turn off the breaker and order a replacement first surge device.

Q: Is installation in a main panel where ground and neutral bus are bonded possible? Do the ground and neutral bus need to be isolated?

Yes, installation in the service entrance panel with bonded neutral is the typical installation. In most cases will provide sufficient protection for all loads in the home. There are some instances where it is good practice to install additional surge protection in a subpanel (ground and neutral isolated). If circuits powered from the subpanel extend outside the home, they are susceptible to surges originating from nearby lightning strikes that will back feed into the subpanel possibly damaging equipment. Also, if the subpanel supplies motor driven equipment there are additional considerations. When motors turn off on and on, they create lower energy spikes that could travel and impact other equipment served by the sub panel or back upstream to equipment powered by the main panel. A percentage of subpanel surges will not travel all the way back to the main panel, but will seek earth via equipment powered by the sub-panel. A lower surge capacity device like FS60 would probably be sufficient for the subpanel.

Q: This might be a dumb question, but how is this different than the siemens tps3a1110d, that costs 4x more than this?

The Siemens TPS3A1110D is a Type 1 SPD, which can be connected anywhere in the system, and is much more robust; whereas a Type 2 device must be connected on the LOAD side of the main panel. Also, the Type 1 device provides EMI/RFI noise filtering, and higher levels of electrical protection, and the MOVs are rated to a different UL classification.

Q: How many joules? (to judge the robustness of the MOV and whether it will need frequent replacement)

FS-140 is rated at 140 kA for a single "transient event". Since this current is shunted to ground we would need to know resistance; current & time over the course of the 'event' to calc total energy (work) dissipated in the MOV's and this would be a non-linear function over the event.
