The F-Series Door Station models include DP38-NBF, DP38-NBKF, DP38-NBZF, and DP38-NSF. These units provide standard door-to-phone communication when used with the DP28-C*. A new design not only brings great new looks, but great new additions as well. A discrete slot is available for an optional third-party 14mm pinhole camera and the weather-proof back box provides quality protection and durability for your unit. All F-Series Door Stations mount into any standard double-gang masonry box as a flush mount. An optional back box (DP38-BXFS) is available as a surface mount. Colors are available in 4 anodized finishes: brass, black, bronze, and aluminum. These Door Stations are also available in kits with the DP28-C as the DP38-BF, DP38-BKF, DP38-BZF, and DP38-SF.
