It’s been expanded, had panel/sounder battery replacements and a new PSU over the years but that’s part of general maintenance. I just haven’t touched the com-ip since.
The sound bomb is pretty pathetic but to create a decent amount of deterring noise inside a small space (garage) while the main sounder is doing it’s job, it’s one more thing to deter; a master blaster is overkill for this and it would be me or the other half that would be on the end of it than a would be thief. I’ve not seen any alternatives such as a mini sounder.
The sound bomb is on one of the outputs. For the config I’m looking at it’s purely notification of the garage being opened when we’re in the house and the alarm is unset.
The ideal/long term is a roller shutter door, set the garage to Area B and use an output to prevent the door being opened without unsetting the alarm to prevent FA. But for now, just knowing the sensors has been triggered beyond chime is the next best option.
