The PA25/3L is normally connected directly to the detector common and remote LED output. Three high-luminosity red LED indicators light up on activation, with a low current consumption. It can be set to to remain on or flash after activation by simply wiring to a different input terminal on the unit. The PA25/3L may also be used in conventional systems requiring low current consumption, connecting it in the same way as described above. In this case, only one LED lights up. The indicator normally stays on (it flashes only if the detector sends the supporting signal)
