The BATB Series Battery Boxes are a distinctive red for use in fire alarm systems. The BATB-40 provides a single level (two battery capacity) of battery storage with an optional shelf that increases the battery capacity to four batteries. The BATB-80 has a mounted shelf and holds up to four batteries. Note: The actual number of batteries the battery box can support depends on the size and weight of the batteries. Refer to Technical Specifications for specific information. These battery boxes are used with the following battery types: Gel-cell Nicad Sealed Lead-acid Wet-cell

The D285 and D285TH detector heads detect the large smoke particles which typically result from wood, paper, and fabric combustion. The D285TH smoke detector also has a +135°F (+57°C) fixed temperature heat sensor. Use in areas where the ambient temperature does not exceed +100°F (+38°C). These detectors are compatible with two­wire or four­wire, 12 VDC or 24 VDC circuits. Also available are addressable bases for use on the POPEX bus.

Use the D307 Remote Test and Indicator Plate with the D296/D297 Long-Range Beam Smoke Detectors and the D340 Series Duct Smoke Detector Housings. This plate has LEDs to indicate the detector's status, test points to read the signal voltage, and a key­operated test switch to test or reset the detector.
