2.5 Removal of the Touch Free Dispenser Beacon from a Nexa™ Touch Free Dispenser.
To remove the beacon, follow these steps:
(1) Open the dispenser by depressing the top latch button.
(2) Remove product bottle (if any) from the dispenser and set aside
(3) Unscrew the captive screw from the boss, to release the beacon and allow it to be removed.
(4) Gently grasp and pull on the TDB to disengage the TDB plug from the communication port.
3. How the Touch Free Dispenser Beacon (TDB) Works.
The Encompass HH CMS TDB is a wireless device that detects and communicates with Encompass HH CMS HCW badges and
Hubs. The TDB communicates with a HCW badge based on its proximity to the device. When the HCW dispenses soap or
sanitizer by placing their hand under the dispenser, a proximity bubble is created around the dispenser. The proximity bubble
wakes up the HCW Badge and begins the information exchange between the devices. The dispenser then communicates
time, date, badge status and ID information (the dispenser ID and badge ID) to a Hub, which relays it on to the remote server.
3.1 Interaction with a Healthcare Worker’s Badge
When the touch free dispenser dispenses product, the attached Encompass HH CMS TDB will momentarily create a
proximity bubble around itself and the dispenser. If the Badge worn by the HCW activating the dispenser is within the
proximity bubble, the Badge will communicate with the TDB and then will change to the proper hand hygiene status level.
If the Badge is not within the proximity bubble, it will not communicate with the TDB nor will its hand hygiene status level
change. This will result in the HCW not receiving credit for using the dispenser.
The default range of the TDB’s proximity bubble is about 24 inches in all directions but the range can be adjusted if
necessary. It is important for the HCW to wear their Badge in a location that insures it is within the TDB’s proximity bubble
whenever a dispenser is activated. It is also important that only one Badge is within the proximity bubble when a
dispenser is activated. If more than one Badge is within the proximity bubble, the TDB may unintentionally communicate
with the wrong Badge (i.e., a Badge belonging to a HCW that did not activate the dispenser). If this happens, the wrong
Badge will change its hand hygiene status level and the wrong HCW will receive credit for using the dispenser.
The Nexa Touch Free dispenser is equipped with a user feedback LED (gold light). This LED is in the same spot as the
battery indicator light, but is a different color (yellow). The feedback LED will only flash when the TDB has successfully
communicated with a Badge. The LED flash will occur during or immediately after dispenser activation. If the LED does
not flash, the Badge may not have been within the proximity bubble or there was an error in communications. If this
occurs, the HCW should move closer to the dispenser and activate it again.
Please take the following steps to insure proper Badge communications and correct HCW credit when using a dispenser.
1. Verify that the Badge is being worn in a location that will be within a TDB’s 24-inch proximity bubble.
2. Before activating a dispenser, verify that other HCWs are not within the TDB’s 24-inch proximity bubble. If there
are other HCWs near the dispenser, kindly ask them to move away before activating.
3. Verify that the dispenser’s yellow LED flashed when the dispenser was activated. If the LED did not flash, move
closer to the dispenser and activate it again.
3.2 Interaction with a Hub
All TDBs are equipped with a longer range radio that allows them to transmit information to the Encompass HH CMS Hubs.
The TDB will transmit to the Hub that is closest to it or from which it gets the strongest signal. At time of system install,
it is verified that all TDBs are in range of at least one Hub.
When the Nexa touch free dispenser dispenses product, the TDB is activated, will create a proximity bubble and search
for HCW badges. If the user is wearing a badge, the Badge’s HH status will be updated by the TDB. The TDB will then
