Notifier EQBB-D4 — four-tier EQ Series equipment backbox in black, the backbox half of an EQ cabinet and supplied without a door.
EQ Series cabinets exist for the hardware a voice system spreads around a building — amplifiers, field power supplies and banks of I/O modules — where ventilation matters more than an operator interface. They share CAB-4 external dimensions but carry no battery row.
- Four tiers, the largest of three EQ sizes; B is two and C is three
- Backbox 24 " wide × 45-3/4 " high × 5-5/32 " deep, in 16 gauge steel
- Top knockout 1.375 and 1.750 "; four lower knockouts 0.875 and 1.125 "
- Takes DAA2, DAX, DS-AMP, DS-DB, DAA-50, DAA-75 and AA-30/100/120 amplifiers
- Also takes ACPS-610, AMPS-24, HPFF8CM and HPFF12CM supplies and XP6/XP10 modules
- UL and ULC listed under S635; CSFM 7165-0028:0243 and :0224
A complete cabinet is a backbox plus a door, ordered separately: pair this one with EQDR-D4, or EQDR-D4R in red, and add TR-D4 for semi-flush mounting. The EQ door is a vented blank taking no dress plate, so Notifier states these cabinets suit neither control equipment nor annunciators.
