Using coloured wristbands the Session Manager can keep track of the number of swimmers in a pool hall at any time of the day, a requirement set by the HSE*.

When a swimmer buys a session they are given a coloured wristband; the Session Manager counts how many of each band has been issued. When a session ends the Session Manager will sound a unique audio alert tone in the pool hall, attracting swimmers' attention to a flashing beacon which will display the colour of the expired session. This instructs all swimmers with the corresponding colour to exit the pool as their session is at an end. The Session Manager will automatically adjust the current bather load to allow for the swimmers which have just left the pool, whilst simultaneously adding any swimmers which have purchased a session during that time.

If the maximum bather load is reached at any time the Session Manager will alert the operator, informing them that they should halt sales until the next session expires.
