The Sentry time delay switch (5650s) is suitable for mounting in Sentry Consumer units and 2 and 4 module Sentry enclosures. The unit offers time delay control of complete circuits within the range of 1 to 7 minutes in increments of 15 seconds.
Note: The time delay switch is not applicable for control of low energy lamps.
Override of the time delay function is only possible by the use of the switch provided on the device and should not be achieved by remote ‘switches’.
The use of PIR is not a recommended method of activating the time delay switch.
The time delay switch may be used to switch on an extractor fan if the fan does not have an over-run facility.
