Figure 3. Wiring a LynxR-I for ECP Mode
Wiring for Zone Trigger Mode
To trip a zone on the 7845i-GSM in V+ trigger mode, the positive triggering voltage from the
control panel must be within 2.0V-14.5V.
Trigger levels above this range may cause permanent damage to the unit.
Trigger levels below this range result in unreliable operation.
To trip a zone on the 7845i-GSM in V- trigger mode, the negative triggering voltage must be
less than 1.0V.
NOTE:
LynxR and LynxR-EN have a designated trigger for V+ trigger.
Connect a wire from the triggering source (bell output, voltage trigger, etc.) of the control
panel to the zone input of the module, and connect a common ground between the module
and control panel.
Examples of zone connections are shown below:
