GR-48/Delay is a device that controls the power supply of a room. It offers 1 normally open (NO) potential free relay contact. There is a delay of at least 60 seconds from the moment the card is removed. It has an indicator LED that is turned on when the card is not placed on the device. This LED helps to locate the device in a dark environment. The GR-48/Delay can easily be placed on a wall mounted bucket. The figure on page 2 shows the GR-48/Delay connection with the use of an external relay. A suitable external relay must be used with a rating, depending on the room’s consumptions.
