DoorProtect magnetic reed switches for door and window openings to notify you (and the intruder or visitor) as soon as the window or door opens. When paired with a HomeSiren you can program these devices to be in Chime Mode when disarmed, ding donging the HomeSiren to let you know someone has entered the property or room. $67.50

Utilising reed switches also enables you to ARM your system whilst at home and walk freely around inside without tripping the alarm. Safety at home. Group your reed switches into areas. Put the front doors into Chime mode so you know when guests have arrived. Great for unattended reception and storeroom areas at work.
