Power outage and health lock

Power Outage - Is there a backup power supply within the cabinet? Can it operate on backup?

During a power outage, the fridge will warm up to room temperature. This process typically takes several hours. The lock will be engaged, and customers cannot unlock the fridge. An external power supply can be added on to temporarily mitigate this. 

Power Outage - What happens if there's a power outage? Do we potentially lose transactions? How does the device come back up?

If the fridge loses power while the door is open, the transaction and onboard computer will not be able to detect items removed. In this unlikely event, the operator can still identify the last customer who occurs and attempt to contact the customer. To deter any tampering, we recommend hiding the wire behind the fixture and/or using a security plug to ensure the main power wire cannot be easily unplugged. When the power is back up, the system will restart, boot up all applications, and resume operation.

Power Outage - What happens if the customer is in the middle of a transaction (door is open) and there is a power outage?

See above for answer.

Power Outage - What happens to the refrigeration units when there is a power outage or mechanical failure, and the unit gets too warm? Does it lock in case of product damage for product health safety?

Yes, if the power outage is long enough, the internal temp has exceeded the food safety parameters, the unit will remain in maintenance mode, and no users can unlock it. A manual override is required to switch the system back online. This will require a health and safety person with access to perform this action. After looking at the temperature graphs, they determined that it was safe to operate. If fresh food has exceeded the food safety law requirements, the operator must follow local food handling laws (ie. remove the bad food and reload) before allowing customers to purchase items from it.

In California, the fridges/freezers must lock if the temp drops too low. And only the operator can unlock. Can you do this?

is there a way to increase the temp at which the food safety alarm goes off? What if a customer holds door open for 5 min choosing an item?

How am I notified of something like this happening?

How do I reset it?

Battery Backup Operation

The battery backup is located at the back of the unit. Its function is to provide power to the controller(s) and mechanical lock(s) during the main power failures so that the controller can keep monitoring the cabinet temperature and activate the lock(s) during prolonged blackouts. The battery backup has eight AA alkaline batteries connected in series to provide 12VDC.

To activate the battery backup, slide the switch to the ON position on top of the battery backup enclosure. To prevent the battery backup from premature charge drain and to extend its lifecycle, slide the switch on top of the battery backup enclosure to the OFF position when the unit is not in use and disconnected from the main power source.

A set of eight new batteries can power the electronic lock safety system controller(s) and lock(s) for about seven hours.

To check whether the battery backup is functioning, follow these steps:

1. Ensure the battery backup switch is in the ON position.

2. Turn the power switch beside the refrigerator controller to the off position to disconnect the main power to the unit. If the controller loses power and the lock engages immediately or within a few minutes, then the batteries in the battery backup enclosure should be replaced. To replace batteries, undo the screw on the battery cover and replace the eight AA batteries with a new set of alkaline batteries. Use high-quality brands such as Duracell, Panasonic, etc. Ensure the battery polarity is followed as per indicators on the backup housing. 

3. Repeat steps 1 and 2 periodically, every 3 to 4 months.
