Power packs are the heart of the low voltage sensor system. A PP20 Series power pack transforms Class I high voltage (120/277 VAC) to Class 2 15 VDC for powering remote sensors. The PP20 and the SP20 Series slave pack are also capable of switching lighting loads on and off using their internal relays. Class 2 wire leads connect to 18 to 22 AWG low voltage cable running to the sensors, making installation easy and clean. Power packs also have an elongated chase nipple that allows it to be mounted either directly through a 1/2 in knockout into a junction box, or inside an adjacent box for meeting specific local code requirements in ceiling plenums. The most versatile power pack is the PP20, which utilizes a patented relay contact protection and can power up to 14 sensors. Dual-circuit control can be handled by two PP20™s, one PP20 2P Series 2-Pole power pack, or a PP20 power pack and a SP20 slave packs.

Utilizing patented relay contact protection the SP20 347 secondary relay pack switches lighting loads on and off. Although plenum rated, the elongated mounting nipple allows for the SP20 347 to be mounted either directly through a 1/2 inch knockout in a junction box, or to be located inside an adjacent box for specific local code requirements. The SP20 347 is commonly used in multi-circuit control applications in combination with one or more PP20 347 units.
