11 I n p u t D e v i c e s Overview The 280B-PL Series detector operates on a fxed temperatur e or combination fxed temperatur e and rate-of-rise principle. When the fxed temperatur e element is activated, the center disc of the detector will fall fr ee. The detector’ s contact rating is 3 amps at 125 V AC and 1 amp at 28VDC. The fnish is matte white. Installation and Mounting Standar d Featur es • Low pr ofle design • Positive operating indication • Easy to install • A vailable in fxed temperatur e and fxed temperatur e/rate of rise • Open cir cuit type • Ulc listed Or dering Information Cat.No. Description 281B-PL Rate-of-rise and fxed temperatur e,135°F (57°C) 282B-PL Rate-of-rise and fxed temperatur e,194°F (90°C) 283B-PL Fixed temperatur e,135°F (57°C) 284B-PL Fixed temperatur e,194°F (90°C) CCS-1182 W ir e guar d IMPOR T ANT NOTE: Independent studies indicate that heat detectors should only be used when pr operty pr otection alone is involved. In cases wher e life safety is a factor , smoke detectors ar e r ecommended.

The guar d is manufactur ed fr om stur dy welded 7 gauge wir e and fnished with a Zinc plating. The detector guar d is stur dy enough to suit most detector locations wher e pr otection fr om impact is r equir ed including gymnasiums or war ehouses. The CCS-1182 is not intended to of fer tamper pr otection. After installation, the alarm LED on the pr otected detector is clearly visible. The CCS-1182 will physically ft over the following detectors: - 281B, 282B, 283B, 284B Heat Detectors - EC10C-3, EC20C-3 Smoke Detectors - EC20FTU-3, EC20RRU-3 Heat Detectors - C2M Smoke Detectors Standar d Featur es • Plated fnish • Low pr ofle • Unobtrusive • Stur dy design • Does not obstruct view of detector’ s alarm LED Or dering Information Cat.No. Description Ship Wt.
