Give Techs Guidance and Training They Need

  • When was the last time you or someone else conducted training for your technicians?
  • What, if any, steps have you implemented to ensure that your technicians are following industry standards and best practices of the alarm industry?
  • Ask your technicians what they need from you, in order to do their job more effectively.
  • Ask your technicians for the type of training they believe would be the most helpful for them, in their day-to-day responsibilities.
