Danfoss 842 two chanell school bell timer.
The unique Danfoss 842
timeswitch & sounder controller is a 7 day commercial and industrial sounder timer with two separate channels that can be individually programmed eg bells ringing in the office with sirens for the factory.
Simply programmed via the unit's keypad with an audible tone verification. For added
it is only possible to enter or change the time or re-program the units with the use of the security key provided.
Applications the unit can be used for are boiler lighting, process control, and pulsed & timed output for break time sounders and bells.
