Tio can create recurrent tasks based on the Topics (equipment) you have in your building. For example if you have Fire Extinguishers then when you create your premises tick 
or if your premises is already created select the premises then from the left menu Manage, scroll down and select the Topic Fire Extinguisher & Blankets and Save.
Tio will create two tasks based on Fire Extinguishers, one for the Building Occupier and one for the Service Provider. Below is the task created for the Building Occupier:
Select the task and choose Modify to add in the date the next visual check is due. When the task has been completed and the visual check of your premises has been carried out the task is ready to be fulfilled, which can be done by selecting fulfil and working through the flow.
Service Provider tasks can be fulfilled in the same way OR if your service provider is using the Tio App and has a list of the assets in your building they can service each asset and then create an entry in your log book along with fulfilling their task. The app can be downloaded from the App Store.
