FAQ
Q1: Can I fish items back out through the slot?
Internal baffles and hopper angles prevent any fishing attempts once items are dropped.
Q2: Are polymer drop safes secure enough for documents?
Polymer models work for light-duty use but lack the pry resistance of steel units; choose based on your risk level.
Q3: How often should I empty the drop safe?
Empty daily or when your deposit volume reaches 75% of hopper capacity to avoid jams and ensure smooth operation.
Q4: Do electronic drop safes need a power source?
They run on AA or rechargeable batteries; premium models may offer optional AC adapters.
Q5: Can multiple users share one safe without compromising security?
Yes—use unique PINs or biometric profiles and review audit logs regularly to track each user’s deposits.
