ATEX II 1 G EEx ia IIC T4|
Alarm Inputs: User selectable as normally open or normally closed.|
LN1000/12 can have up to 12 inputs which must be isolated.
LN1000/32 can have up to 32 inputs which must be isolated.
Inhibit Inputs: Each alarm channel can be individually inhibited to prevent alarms being activated.
Pushbutton Inputs: Four membrane pushbuttons are fitted to the front facia as standard. Terminals are provided for remote pushbuttons to be wired into the LN1000. Pushbutton functions are Test, Acknowledge, Reset, Silence.
Alarm Card Outputs||
Each dual-channel alarm card has two group outputs per alarm channel. These may be configured to follow the alarm logic, follow the input, or follow the horn. These outputs are ideal to drive DA-149 I.S. relays which in turn can be used to control external devices in either the hazardous or non-hazardous location.|
Sequence Card Outputs||
Horn: To drive the DA-125 horn powered by the annunciator.|
External Sound: Used to switch a DA-149 I.S. relay to control external sounders.
Groups: Two group outputs to drive DA-149 I.S. relays. One is configurable to follow the alarm logic or alarm contacts, and the other functions as a reflash ouput which gives a 1 second pulse on the occurrence of each new alarm.
18-35VDC at 100mA into a suitably certified isolated I.S. interface located in the non-hazardous location. Exloc can provide this.|
