PEMA is looking for a few good volunteers who can support our Auxiliary Communications Services team (ACS) during activations and exercises.

An ACS unit is a great place to volunteer ones time and efforts, and it can be interesting and meaningful. PEMA's ACS team activates whenever the State Emergency Operations Center (SEOC), and/or one of the PEMA Regional Offices, is activated for disaster response or a significant event. 


Activities can include field response with communications vans, mobile or portable units, equipment caches, or operations at one of the PEMA Area Office Communications Centers (Indiana or Hamburg), or at the SEOC in Harrisburg with the PEMA ACS unit or with a county or regional task force unit.

PEMA ACS is taking applications for the folowing volunteer positions:

  • Stenographers or secretarial staff who can transcribe voice communications
  • Computer networking specialists who can work with digital communications
  • Licensed GMRS and/or Amateur Radio communications specialists



For more information, and/or an application to join a Commonwealth ACS unit or contact information for a local ACS/RACES unit, please use the contact information below and your request will be forwarded to the appropriate ACS/RACES Officer.
