42ADA220 Application Guide
5. Synchronizing NAC Power Extender Using Built-in Sync Protocol:
AL642/AL842/1042ADA220 have built-in protocols to support Potter/Amseco, Gentex
®
, System Sensor
®
,
CooperWheelock
®
two-wire synchronizable devices, therefore an external sync module is not required
(Output
Programming Selection Table, pg. 6)
. In these modes, Input 1 is always used to activate visual notification appliances
(strobes), and Input 2 is used to activate and silence audible notification appliances (strobes).
Note:
Input 1 has to be activated in all the configurations.
