The new 8-channel Digital Timer device is a direct replacement for the Danfoss 841 & 842 timers. The Danfoss 841 & Danfoss 842 were very popular digital timers, but are no longer available, this is why we have sourced an alternative digital timer unit. Our 8 Channel Digital Timer is perfect for use as a School Break Timer and Class Change Timer. Not only is it an alternative to the superseded Danfoss Timers but it has improved functionality and simplicity of use.
Easily Programmed for Class Change
The 8-channel timer can be easily programmed to sound a different number of rings to identify different year group class changes, for example;
- 1 ring for Year 1
- 2 rings for Year 2
- 3 rings for Year 3
It is designed to provide programmed weekly event switching of 8 independent relay outputs, controlling devices such as bell timing, class change signal generators, shift start/stop tone generators, etc.
The Digital Timer provides NO (Normal Open) or NC (Normal Closed) relay contacts to each of its 8 relay outputs and supports switching up to 64 events per day (32 On and 32 Off).
This compact, yet highly robust device is easy to programme and control and is ideal for education, industry and retail applications where the scheduled broadcast of tones, messages, alarms or recorded audio files/tracks is required on an ongoing, repetitious basis.
Further functions of this Digital Timer Unit include event manual override, DST (daylight saving time) compensation of spring / autumn time changes and clock tuning for maintaining accuracy of timer.
A clear blue LCD screen displays the Timer status as well as menu functions for programming and set-up. Push buttons control the user interface for programming and a row of 8 green LEDs provide a visual indication of when each relay is active. The relay outputs and power are connected via removable phoenix terminals which are housed under a removable security cover to prevent unauthorised access or tampering. Removable brackets allow the Timer to be securely surface-mounted or installed within a PA rack.
