The DSC Wireless Mini Door/Window Contact, practically unnoticeable once installed, is ideal for tough-to-fit installations and features a pre-installed coin cell battery.

In having the batteries pre-installed, installers save time as they don’t have to handle batteries or open casings to insert them prior to mounting. A generous magnet gap of 5/8” (16 mm) provides flexibility during difficult installations as it easily accommodates larger door or window frames. Multiple mounting options further help to reduce installation time

Includes a long life pre installed coin cell lithium battery that is user replaceable. Battery life is estimated at 5 years under normal use. Also includes powerful contact magnet that allows up to a 5/8" gap distance.
