Locknetics RDB4 4 O/P Relay Relay Distribution - Board Only

The RDB4 is a 4 output relay distribution option board. It drops into a Locknetics LP Series power supply so a single supply can be split and managed across multiple outputs instead of feeding one device directly. If you are powering several locks or access control devices from one LP supply, this is the board that distributes and switches that power.

Board only. The RDB4 ships as the bare relay distribution board, so you need an LP Series power supply already in place (or ordered separately) to host it. There is no housing, no transformer and no power supply board in the box.

The RDB4 is the option board for the Locknetics LP Series, which includes 1.5 amp and 2.5 amp supplies used to power electronic access control devices on single or double door openings. Ordering an LP supply for a multi-door job and want switched distribution? That is exactly what the RDB4 adds.

No, they do different jobs. The RDB4 is a 4 output relay distribution option board that mounts into a Locknetics LP Series power supply to manage and distribute power to connected devices; it is a board only, with no enclosure or transformer. The Adams Rite 4605 is a regular transformer that converts 115 VAC to 12/24 VAC with a 40 volt-amp output, so it is a power source rather than a distribution device. If you already have an LP Series 1.5 amp or 2.5 amp supply and need to split its output across multiple doors, the RDB4 is the piece you want; if you need low voltage power in the first place for a single device, a transformer such as the 4605 is the type of product to look at.

The LP Series supplies are UL294 certified Class 2 power supplies with field selectable output voltage, a built-in battery backup charger and fire alarm integration capability. That listing belongs to the LP supply itself; the RDB4 is the relay distribution option board that mounts into it.

It is a field-added option board. Locknetics built the LP Series around an industry common power supply board footprint so field replacement and upgrades are straightforward, and power distribution is expanded by adding the RDB4 board. Existing LP Series supply in the closet? The board goes in without swapping the whole supply.

No. The RDB4 only distributes switched power outputs from an LP Series supply. For an exit signal you want a switch kit matched to your device, such as the Command Access REX-KIT-ML for ML1-Series mortise locks, the CRSREXKIT-ED for Cal Royal 22/98 and Sargent 80 Series exit devices, or the SCHLBMKIT-ML latchbolt monitor kit for Schlage L9000 mortise locks.

For a single opening with no distribution or switching needed, a plain transformer does the job. The Adams Rite 4605 steps 115 VAC down to 12 or 24 VAC with a 40 volt-amp output. The RDB4 only earns its place when you are splitting one LP Series supply across several outputs.

They sit at different points in the system. Request-to-exit kits such as the Command Access REX-KIT-ML for ML1-Series mortise locks, the CRSREXKIT-ED for Cal Royal 22/98 and Sargent 80 Series exit devices, and the CYREXKIT-ED for Corbin 5000 and Yale 7000 exit devices are field installable switch kits that generate a signal from the door hardware when someone exits. The Locknetics RDB4 is a relay distribution board that fits an LP Series power supply and provides four relay outputs for distributing power to access control devices. A typical opening uses both: the REX switch supplies the input signal, and the relay board handles the switched power going out to locks or strikes.

No. The Locknetics RDB4 is a 4 output relay distribution option board that adds switched power outputs to an LP Series power supply. For door status reporting, a monitoring switch kit is the correct product type: the Command Access SCHLBMKIT-ML is a field installable latchbolt monitor switch kit for Schlage L9000 mortise locks in an SPDT configuration. The two are commonly specified together on the same opening, the monitor kit reporting position back to the panel and the RDB4 feeding power out to the locking devices.

The Locknetics RDB4 is a power distribution board only and produces no sound or annunciation. For audible output at the opening, look at devices built for that purpose, such as the Adams Rite 29-0218 piezo electric horn with multi-voltage compatibility or the RCI 914 Series delayed egress sounder with field-selectable volume output up to 102dB. These can be powered from an LP Series supply, and the RDB4 is what lets you take four separate switched outputs off that one supply to feed them along with your locking devices.

No, those solve different halves of the problem. The RCI 9500/9501 Series mortise pin transfer carries power from the frame into the door leaf with a tamper-resistant design rated 1.5A at 24VAC. The Locknetics RDB4 stays inside the power supply enclosure and is a 4 output relay distribution board that divides one LP Series supply among multiple devices. On an electrified lock installation you would typically use both: the RDB4 to create the individual switched outputs, and a transfer device to get each one through the door edge.

Commercial. The RDB4 is catalogued for commercial access control work, which is where LP Series supplies and multi-door relay distribution get used: office buildings, schools, healthcare, multi-family common doors.
