Frequently asked questions

Common questions about SENTINEL from 3G Electric.

What are the key differences between SENTINEL pass-through and non-pass-through evidence lockers?

SENTINEL pass-through lockers have doors on both the front and back, allowing evidence to be deposited from one side and retrieved from the other, which is useful for evidence intake and distribution workflows. Non-pass-through lockers have a single door on one side, suitable for storage-only applications. Both types are available in standard and refrigerated models, with compartment counts ranging from 4 to 18.

What power requirements do SENTINEL refrigerated evidence lockers have?

SENTINEL refrigerated evidence lockers require a dedicated 115 Vac, 60 Hz, 15 Amp circuit. This is specified for models such as the ERF42 and ERF82 series. The units ship assembled and are designed for plug-and-play installation, but the electrical supply must be verified by a qualified electrician to meet local codes.

Are SENTINEL evidence lockers shipped assembled or require on-site assembly?

All SENTINEL evidence lockers ship fully assembled. This includes both standard and refrigerated models, regardless of compartment count or backing type. The assembled delivery reduces installation time and ensures structural integrity, as the units are factory-welded and tested before shipment.

What locking mechanisms are available on SENTINEL evidence lockers?

SENTINEL evidence lockers offer several locking options: slam latches for quick closure without a key, keyless lift latches that require a code or tool, and keyed locks for individual compartments. The choice depends on the security level and access control requirements of the facility. For example, the 05AA-NPT uses a slam latch, while the 12AA-PT uses a keyless lift latch.

Can SENTINEL evidence lockers be used for items other than evidence, such as firearms or gear?

Yes, SENTINEL lockers are designed for secure storage of various items, including firearms, ammunition, and personal gear. The heavy-gauge steel construction and tamper-resistant features make them suitable for weapon racks and gear lockers in armories or patrol stations. However, specific models like the ERF series are optimized for evidence with refrigeration, while standard models are more versatile for general secure storage.
