SOME TYPICAL MODES OF OPERATION FOR IU 400 CONNECTED TO A NUMBER OF GD 475
1. Normal operation in DAY mode, alarm relay programmed to LATCH:
 GD alarming => IU Alarm relay opens and remains open. LEDs on IU and
GD are lit until reset.
 Reset of IU and GD can be done in three ways, with button on IU,
switching from DAY to NIGHT or power down of IU.
2. Normal operation in NIGHT mode, alarm relay programmed to LATCH:
 GD alarming => IU Alarm relay open and remains open. LEDs on IU and
GD are off.
 Reset cannot be done until IU is set to DAY.
 When set to DAY, IU and GD LEDs are lit.
 Reset of IU and GD can be done in three ways during DAY:
1. with button on IU or
2. Switching from DAY to NIGHT or
3. Power down of IU
3. Normal operation in DAY mode, alarm relay programmed to AUTO:
 GD alarming => IU Alarm relay opens for 3 seconds. LEDs on IU and
alarming GD are lit steadily.
 Automatic reset is executed only on Alarm relay
 Additional alarm will again cause Alarm relay to open for 3 sec.
 Reset of IU and GD can be done in three ways, with button on IU, from
DAY to NIGHT or IU power down
 Notice: Automatic reset is only valid for Alarm relay
4. Normal operation in NIGHT mode, alarm relay programmed to AUTO:
 GD alarming => Alarm relay on IU open for 3 seconds. LEDs on GD and IU
remain off.
 Automatic reset is executed only on Alarm relay
 Additional alarm will again cause Alarm relay to open for 3 sec.
 Reset of units cannot be done in NIGHT mode.
 When switching to DAY mode, the LEDs on IU and alarming GD are lit.
5. Fault on IU in DAY mode and alarm relay programmed to LATCH:
 At fault on loop both Alarm and Fault relay open and remain open and
LED on IU blinking if:
 Loop current <3mA or > 30mA

 Loop voltage <7,5V in DAY or <5,5V in NIGHT
 Reset of IU can only be done with IU button or power down when fault is
repaired.
 At Fault the reset by function DAY => NIGHT is inactivated. To reset by
this function the fault first must be repaired and unit reset by IU button.
6. Fault on IU in Night mode and alarm relay programmed to LATCH:
 Alarm and Fault relay open and remain open.
 No LED indication on IU.
 Reset of IU can only be done in DAY MODE with IU button or power down
when fault is repaired.
 Change to DAY mode will cause LED on IU to start blinking.
7. Fault on IU in DAY mode and alarm relay programmed to AUTO:
 Alarm and Fault relay open and remains open.
 Reset of IU can only be done with IU button or power down when fault is
repaired.
 At Fault the reset by function DAY => NIGHT is inactivated. To reset by
this function the fault first must be repaired and unit reset by IU button.
8. Fault on IU or GD in NIGHT mode and relay programmed to AUTO:
 Alarm and Fault relay open and remain open.
 No LED indication on IU.
 Reset of IU can only be done in DAY with IU button or power down only
when fault is repaired.
 At fault the reset by function DAY => NIGHT is inactivated. To reset by this
function the fault first must be repaired and unit reset by IU button.
 Change to DAY mode will cause LED on IU to start blinking.
9. Programming of loop current:
 Programming of normal loop current is made when all detectors are
installed correctly and there is no Fault indication (wait 30 seconds after
power-up).
 Change the jumper S1 briefly to Open-> Closed-> Open (approx. 0,5sec)
 Now programming modes can be done. Select AUTO mode (S1 = closed)
or LATCH mode (S1 = open).
