LSE Annunciator system New Value/First-up Indicator

Description General

The LSE New Value/First-up Indicator is designed to signalise technical faults according to the DIN 19235 sequence. You may choose between New Value or First-up indication. The units are front mounted in a standard cut-out. All electrical connections are realised by plug-in screw terminals on the back of the unit. Therewith, unit changes and mensurations are easily to realise. To build larger systems with a higher amount of inputs than a single device offers, it is possible to connect up to twelve units. The front is equipped with 8 or 16 red alarm LED's and one green LED to indicate the normal condition. In addition to this, buttons for the lamp test, alarm acknowledgement, horn acknowledgement and a buzzer are built in. The acknowledgement and lamp test can also be realised by external buttons. The unit provides one potential free contact (NO) for the audible device / horn and two contacts (NO) for group and common alarm with the same potential. The supply- and signal voltage is available in many different varieties. As an option the units are available with output relays. It is also possible to produce the Common Alarm Indicator without buttons and buzzer or with a time delay for all inputs.



Function

New Value Indication
Each incoming alarm is indicated by the corresponding visual indicator flashing. At the same time the relay output is activated for an audible alarm (connectors 3 and 4) When the lamp acknowledgement button is pressed, the visual indicator changes from flashing to continuous light, when the alarm still persists. If a further alarm occurs after the horn has been acknowledged but before lamp acknowledgement, the horn remains inactive and the visual indicator flashes until lamp acknowledgement. If the alarm has meanwhile disappeared, the visual indicator goes out. The audible alarm is acknowledged separately.

First-up Indication
If several alarms arrive, only the alarm which has occurred first is indicated by flashing light. If the alarm becomes inactive before the lamp is acknowledged, the indicator flashes until the lamp is acknowledged, then it turns off. If another alarm arrives after the horn is acknowledged but before lamp acknowledgement, the horn is reactivated. All other alarms are indicated by continuous light as long as they persist. At the same time the relay output is activated for an audible alarm (connectors 3 and 4).

Common alarm
The function of the common alarm relay can be programmed as followed:

DIP switch 7 off / DIP switch 8 off
  • Dynamic static, with each incoming alarm the common alarm relay is activated in step with the flashing frequency until lamp acknowledgement. After acknowledging the alarm, the indicator changes to continuous light until the alarm disappears. With each new alarm the relay is activated until lamp acknowledgement.
    DIP switch 7 on / DIP switch 8 off
  • Static, the common alarm relay is activated by the first alarm to arrive and stays active until the last alarm disappeared
    DIP switch 7 off / DIP switch 8 on
  • Static until LQ, the common alarm relay is activated by the first alarm to arrive and stays active until lamp acknowledgement. With each new alarm the relay is activated until lamp acknowledgement.
    DIP switch 7 on / DIP switch 8 on
  • Dynamic until LQ, with each incoming alarm the common alarm relay is activated in step with the flashing frequency until lamp acknowledgement. With each new alarm the relay is activated until lamp acknowledgement.
    Group alarm
    The group alarm relay is active as long as a signal input of the own device is active. The relay switches off when all signal inputs of the unit are off.

    Lamp test
    The lamp test button activates all LED's for about 4 seconds. If several units are connected together the lamp test is overlapping.

    Audible device / horn
    The internal buzzer and the horn relay are activated by the signal inputs.
    The relay stays active until acknowledgement even when the signal inputs went off meanwhile. Acknowledgement is possible with the HQ button or an external switch.

    Signal inputs
    The signal inputs can be changed in two groups from NO normally open to NC normally closed with the DIP switch No. 3 and 4. Units with 8 signal inputs have two groups of 4 inputs, units with 16 signal inputs have two groups of 8 inputs which can be programmed.

    Output relays (optional)
    The output relays are connected to the signal input carrying the same number. The function can be programmed with the DIP switches 5 and 6 as followed:

    DIP switch 5 off / DIP switch 6 off
  • Relays remain activated until acknowledgement
    DIP switch 5 on / DIP switch 6 off
  • Relays as an image of the visual indicator (change blinking, static)
    DIP switch 5 off / DIP switch 6 on
  • Relays as an image of the signal input
    DIP Switch 5 on / DIP Switch 6 on
  • Relays without function
