2.7 Connecting the relays
The U•H1 unit has three relays that can be addressed by the alarms, a technical-fault relay,
and an alarm repeater relay. Diverse types of devices can be wired to these relays, such as
air blowers or extractors, sirens, LED warning signs or flashing lights, etc.
2.8 First start-up
Before you power on your U•H1 unit, please ensure that the terminals have been tightened
properly and the power voltage is in the acceptable operating range for the U•H1 unit.
Please contact DALEMANS sa/nv to set up a commissioning appointment.
The LEDs on the motherboard must light up when the device is powered on. It is important
that the user checks that these are all green and not flashing, except for the yellow LED on
the right-hand side of the motherboard, which should flash on and off at one-second
intervals.
Immediately after the unit is powered on, the LCD screen on the unit must turn blue and the
buzzer should make a short, uninterrupted sound.
