The 4500TS timer is equipped with our exclusive electronic timer S25T along with a coin acceptor. The rust-free stainless steel small cabinet makes it ideal for wet environments such as campground showers or any indoor or outdoor applications. Time is adjustable from 1 second up to 63 minutes per coin inserted. Two LED indicators tell about the current state of the timer. 


Additional Description


Here are the different configurations available with the 4500TS

Automatic start:  

This is the default set-up.  Session starts once the amount inserted reaches the starting value (starts either on the first or second inserted coin).  All other coins inserted by the user will simply increase the time.  Time is cumulative.  

Differed start and end-of-session warning with the optional SLB Module: 

When equipped with the SLB Module, the differed start requires the user to press on a lighted start button to start the session.  With the Pause mode activated, it is then possible to pause the time (and water flow if installed on pay shower) simply by pressing on the button. 

End-of-session warning with SLB Module: 

The SLB Module embedded beeper will warn the user about the upcoming end of the session.  With a simple dipswitch on the S25T controller, you can choose between a warning that will last for the entire last minute or the last 15 seconds of a session.  During this period, the beeper and the lighted button will both activate.  The volume of the beeper is also adjustable.
