I would like to use use AS-I safety modules in networks with more than the 31 slaves.

Will AS-I safety work on A/B networks with up to 62 slaves ?

No.
Safety modules use both A&B;channels.
Therefore a Max of 31 safety devices per network are permited.

Public safety agencies want to improve their effectiveness and responsiveness to incidents within or outside their jurisdiction.I understand that A, B, C and D are just grades for compliance and I am wondering the safety modules use both A and B channels.

The public safety agencies want to the improve their effectiveness and responsiveness to incidents within or outside their jurisdiction. These agencies need even the better interdepartmental and intergency.The Divers alert network is a non profit organization devoted to assisting divers in need.
