Ingress

A maintained emergency luminaire may be energised at all times. A non-maintained emergency luminaire is only energised when the power supplied to normal lighting fails.

PUSH Dimming: A dimming method using a simple retractive (non-latching) switch. The input from the switch to the driver is in addition to the main power supply to the driver. With Primary PUSH dimming, an additional live with a retractive switch and a neutral are connected to the driver. Normally a short push of the switch turns the driver on/off, while a long push dims up and down. The switch operation is the same with Secondary PUSH dimming but the supply to the switch comes from and returns to the driver via the retractive switch, usually at a reduced voltage. PUSH dimming may also be called Switch DIM.
