You may be able to use the 283B-PL or 284B-PL instead if you only need fixed temperature. Earlier detection may be obtained by reducing the spacing between detectors.

Mounting plate may be surface mounted or mounted onto any 3 1/4″ (83mm) or 4″ (102mm) octagon box.NOTE: Effective July 1, 2015, the 281B-PL and 282B-PL detectors will no longer be manufactured.
