If the unit is supplied with AC the system outputs LT/LQ/HQ are disabled. Switching on the system The LSE-D16 Indicator unit has no master switch. The system is alive as soon as the power supply has been switched on. A switch must be provided in the building installation as a cut-off device. The switch must be labelled appropriately, must be in the vicinity of the equipment and must be easily accessible to the user.

Schematics The outputs LT (Lamp test), LQ (Lamp ack.) and HQ (Horn ack.) are only enabled using a DC power supply. The LT, LQ and HQ functions can be customised, see page 9, output functions. The outputs are designed as a current sink and are not potential-free.
Control elements The following buttons are integrated in the front of the unit: Horn acknowl. The output 9, Horn acknowledgement is activated The output 10, Lamp acknowledgement is Lamp acknowl. activated All LEDs, the buzzer as well as the lamp test Lamp acknowl.
Power up the unit and push the HQ and LT keys at the same time within 10 seconds. If no other keys are pressed within 5 seconds, LSE-D16 will switch back to operating mode. If additional keys are pressed, the programming mode remains active for 30 seconds.

When the programming mode is activated, LSE-D16 indicator unti starts at the level 1. The levels can be changed in active programming mode using the HQ and LT navigation keys. If for example Level 2 is active on operating input 1, pushing the HQ keys switches the LSE-D16 indicator unit to level 1.
