Detex BE-961 Battery Eliminator | 120VAC to 9VDC | Standard or Supervised 95 dB Alarm

Reduce routine 9-volt battery replacement at compatible commercial security doors with the Detex BE-961 Series Battery Eliminator. These compact wall-mount battery-eliminator assemblies convert building 120VAC power using an included 120VAC-to-12VAC external transformer, then produce the specified low-voltage DC power for compatible 9V Detex security devices. Both configurations include an approximately 10-foot flexible armored connection conduit, LED power-status indication and a cast-aluminum enclosure.

Select the correct model before ordering: BE-961-1 is the standard battery eliminator without an internal supervisory alarm for manufacturer-approved Detex ECL, V40/V50 EB and EAX 9V devices. BE-961-2 adds a supervised power loop and built-in approximately 95 dB alarm that sounds if the protected power-feed wires are cut or the connected ECL alarm activates. Detex specifies BE-961-2 for ECL-230 and ECL-600 family exit-control locks only — not V40 or EAX alarm devices. Neither model is a battery-backup charger or a complete exit locking system.

Compare the Available BE-961 Models

Ordering warning: The models are not functionally interchangeable. If the application needs the BE-961-2 secure power-feed alarm, choose the supervised model. If the equipment is a V40 EB, V50 EB or EAX alarm, choose the BE-961-1 only when compatible with the precise device version and Detex's current wiring instructions. A listing elsewhere describing BE-961-2 for V40 devices does not override Detex's ECL-only restriction.

Key Features and Benefits

• Detex OEM battery eliminator: Manufacturer-designed battery-replacement power source for specified security door equipment, reducing routine disposable 9V battery changes.
• Standard 120VAC building supply: Both versions include an appropriate external transformer, specified as 120VAC input / 12VAC secondary, feeding the conversion board's regulated low-voltage output.
• 9VDC device power: Power source for properly specified battery-operated Detex security equipment; confirm jumper settings and per-device voltage before installation.
• Supervised alarm choice: The BE-961-2 monitors the secure power-feed loop and provides a built-in approximately 95 dB audible alarm in response to a cut line or connected ECL alarm. The BE-961-1 does not provide this feature.
• ECL-only BE-961-2 compatibility: Detex limits the supervised 961-2 model to compatible ECL-230 and ECL-600 series exit-control locks, not the V40, V50 or EAX alarm lines.
• Broad BE-961-1 compatibility: The standard 961-1 can power certain approved ECL, V40 EB, V50 EB and EAX devices that use compatible 9V power; verify exact versions and technical requirements.
• 0.5A maximum output capacity: The Detex BE-961 series technical literature specifies 0.5 amp current-output capacity. Never exceed the combined rating or device-specific wiring limits.
• Up to three supported 9V devices: The manufacturer advertises up to three compatible ECLs or three EB devices for the standard BE-961-1. For BE-961-2, connect only the supported ECL locks and follow the supervised-loop loading/wiring instructions; never assume compatibility solely from the total number of devices.
• 10-foot flexible armored conduit included: Low-voltage connection may run between the wall-mount eliminator enclosure and the door security device, with an approved mounting and transfer method that will not obstruct operation.
• LED power-status indicator: Helps maintenance technicians check energized power at the eliminator.
• Compact standard cast-aluminum enclosure: Nominal dimensions 4-5/8 × 4-5/8 × 2 inches excluding conduit and external transformer.
• Input transient suppression: Manufacturer-described electrical protection for normal building-power disturbances.
• Commercial installation: Suited to stores, institutional facilities, warehouses, schools and other approved indoor installations with compatible Detex alarms or ECL exit-control locks.
• Detex limited warranty: BE-961 product literature identifies a three-year limited manufacturer's warranty, subject to current terms.

Shipping Information

BE-961-1: 3 lb shipping weight. BE-961-2: 3 lb shipping weight. Distributor-listed shipping cartons for this product family are approximately 10 × 7 × 5 inches. These packed weights are separate from the case dimensions of 4-5/8 × 4-5/8 × 2 inches. The BE-961-1 original Shopify weight and stock have been preserved. Verify actual warehouse packaging or carrier weight before purchasing a shipping label.

Installation and Life-Safety Information

Have a qualified installer follow the current Detex installation instructions 101320 and the exact connected-device installation manual. Verify the utility supply, transformer hookup, output jumper settings, connector and cable routing, maximum combined current, ground/short protection, and compatibility of the installed lock with the selected BE-961 model. The 95 dB supervised alarm is available only on the BE-961-2 ECL-specific configuration. Do not use that version with V40, V50 or EAX devices unless Detex provides explicit approval for the exact hardware; manufacturer catalog restrictions take precedence over third-party retailer summaries. The battery eliminator is not an emergency power backup, exit device, delayed-egress timer or fire-alarm release system.
