"Traffic Light" Door Status Indicator
The SR1-PTL-150 Door Status Indicator provides a "traffic light" style indication using large green and red LEDs in a white plastic single-gang configuration to match common electrical fittings.
The indicator can be surface-mounted using the supplied 19mm-deep white-plastic surface box or can be flush-mounted onto a standard UK single-gang box.
LED control is via three control wires - green (common), yellow (red LED) and blue (green LED). By connecting the corresponding LED control line to the green conductor the LED will then illuminate. Both LEDs can be illuminated simultaneously if required by connecting both LED control lines to the green conductor.
Power (12VDC - 24VDC) is applied to the two red wires.
A jumper link P1 on the internal circuit board can be used to enable a flashing mode. The flash-rate of the LEDs will be approximately 85 flashes per minute when enabled.
