The 842 is one of the models within the MK8 range of 7 day commercial and industrial controls. This range includes on/off units for boiler, lighting and process control, and pulsed output units for bellringing or siren sounding applications.

Programme entry is via a membrane keypad with audible feedback. For security it is only possible to enter or change the time, programme and extend duration with the removable key in place and turned to the setting position.

The pulsed units, 841 and 842, feature programmable duration and pulse type, continuous or intermittent. The Auto/Off/Man rocker switches allow the output to follow the programmed events, to be switched off, or to be manually on while the switch is held down in this position.
