The WDK-ERA-KIT-922-BELL is a doorbell kit specifically designed for warehouses, shops, garages, etc., where noise is an issue, and you need a loud doorbell or entry alert. The receiver featured in this kit, the ERA-DCRX, has a volume control knob that plays the selected melody at approximately 95 dBA at 5 feet, which is loud but not loud enough in some locations.

A unique feature of the Safeguard Supply ERA-DCRX is its C-FORM relay and 4 x 12V DC outputs, allowing you to connect strobe lights, sirens, and fire alarm bells–virtually any 12V DC product.

For more information about the WDK-ERA-KIT, please visit the product page; you can consult the user manual. This article will illustrate how to connect the DB-2000 bell to the ERA-DCRX.

Unplug the receiver (ERA-DCRX) & separate the top half from the lower half of the case, and set it aside.
On the DB-200, remove the square cover on the top half of the bell. See image below

Notice the small tab on top of the square cover. Depress the cover and remove it from under the tab. Set it aside.
On the ERA-DCRX receiver, locate the external 12V DC terminal connection block corresponding to the ERA receiver’s respective zone (figure 1). For example, if a push button is paired to zone 1, and you want sound for zone 1, you must wire the bell into the terminal block for zone 1.
Loosen the + and – screws for the respective zone referred to in the step above.

Connect a wire to each screw (see the image below) and retighten.
Connect the other end of the wire to the + and – screws on the terminal block of the ERA-DCRX for the zone you plan to program the transmitter/sensor to and retighten the screws.
Polarity does not matter.

My ERA-DSTX Detection Range Dropped From 25 Feet to 15Nine times out of ten nothing has failed. A PIR sensor’s usable range is a moving number set by battery voltage, thermal contrast against the background, and the angle at which the target crosses the beam pattern — none of which show up on a thermometer or a tape measure. Work the checks below in order. Most cases resolve at step 1 or step 3.How Far Will My ERA-DSTX Driveway Sensor Really Reach?A PIR sensor doesn’t measure distance — it measures contrast. It sees a target only when that target is meaningfully warmer or cooler than whatever sits directly behind it, and only when the target moves across the lens’s detection pattern rather than straight at it. Change the background temperature, the approach angle, the battery voltage, or the amount of film on the lens, and the same sensor in the same spot will “lose” ten feet of range with nothing visibly different.Understanding the 12V DC Outputs on Your ERA-DCRX Receiver: A Guide to Zones, Strobes, and BellsIntroduction to the ERA-DCRX Receiver The ERA-DCRX receiver is the heart of your long-range wireless doorbell system, designed for business and warehouse environments.
