In the event of an alarm the control unit NRS 1-40.1 / NRS 1-40.2 does not lock
automatically. If a lock function is required by the installation it must be provided in the
follow-up circuitry (safety circuit). This circuit must meet the requirements of
DIN VDE 0116 (EN 50156).
Start
Apply mains voltage.
LED “Power” is illuminated
Mains voltage applied
LED 1–4 are flashing
System is being started and tested.
Output contacts are open.
Signalling output is closing (lamp test).
Operation
Limiters 1–4 indicate
no alarm
LED 1–4
are not illuminated
Output contacts are closed,
signalling output is open.
Alarm
Limiters 1–4,
one or more limiters
indicate an alarm
One or more of the LEDs
1, 2, 3, 4 are flashing rapidly
De-energizing initiated,
signalling output is closed instantaneously.
One or more of the LEDs
1, 2, 3, 4 are illuminated
De-energizing period has elapsed,
output contacts are open,
signalling output closed.
Test - Limiters 1–4
During operation:
Press key 1, 2, 3 or 4 and
hold it down until the end of
the test, limiters must react
as if there was an alarm.
LED 1, 2, 3 or 4
is flashing rapidly
Alarm simulated in limiter 1 - 4.
De-energizing initiated,
signalling output is closed instantaneously.
LED 1, 2, 3 or 4
is illuminated
De-energizing period has elapsed,
output contacts are open,
signalling output closed.
Test finished.
