Mr Trass said they talked about their proposal to the Fire Service, which presented them with options. They chose one that would be available 24/7, at a cost of about $8000.
They then applied for funding through the Grassroots Trust. That was approved this month and the equipment delivered this week.
"We chose Indigo as a location because the restaurant is a great supporter of local events, such as the Downtown Festival, and being open seven days a week until midnight, it was the logical choice," Mr Trass said.
A code was required to open the box, which could be obtained by ringing 111, or by asking restaurant staff, Mr Bates said.
Instructions were included with the device, but there would be practical assistance on hand as well, he added.
"We plan to bring people into train our staff on how to use it and are also going to invite staff from the other restaurants, bars, cafes and hotels in the area to be trained as well."
Mr Bates said it was a great way to give back to the locals who supported the business.
"We would prefer not to ever have to use it, but it does bring peace of mind."
