With three included, you can usually protect main living areas, hallways, front office zones, stock rooms or internal access points much more effectively than a standard one-sensor starter kit. 2 × Door / Window Contact SensorsThese are ideal for protecting the main front door, rear entry, office door, roller access door or selected windows. They create an important first layer of perimeter protection before an intruder gets deeper into the site. 2 × Remote Key FobsThese allow fast arm and disarm operation without needing to use the app every time. They’re convenient for family members, staff, managers or trusted users who need quick control of the system. Indoor Wireless Siren – ARA12-W2The indoor siren adds another deterrence layer inside the property. It helps alert occupants and makes the environment much harder for intruders to remain in once the alarm is triggered.
