— ENGINEERING CANDOR · WHEN /AG IS REQUIRED VS. OPTIONAL

−4°F isn’t always free. Spec it when the room earns it.

Standard EM20-CMB/260DC operates 32°F to 122°F with a LiFePO4 battery rated for 500 full cycles. The /AG adder extends the lower bound to −4°F (and the upper bound to 140°F) — at the cost of made-to-order lead time and a price premium. Specify /AG for refrigerated warehouses, walk-in freezer egress, outdoor enclosures, and unconditioned attics. Skip /AG for office, healthcare, and education spaces where the conditioned envelope handles the temp range.

/XD (120-min extended discharge) is not currently offered on the EM20-CMB chassis. If 120-min egress is required by AHJ, specify EM08-HMB/170DC/XD or EM08-YTB/60DC/XD from the Tier 01 catalog.
