Bracket-mounted loudspeaker D1xL2F

for hazardous areasrobustfire-resistant

Product overview
The D1xL2F is a 25W PA loudspeaker with a re-entrant flare horn designed for high SPL public address and signaling in hazardous areas. The unit is housed in a marine-grade, corrosion-proof LM6 aluminium enclosure (Type 4/4X, IP66/67) suitable for Class I & II Div 1 and Zone 1, 20 and 21 explosion-proof applications.

Description
The flare re-entrant horn is high-impact, fire-retardant thermoplastic and is field replaceable. The driver uses a standard 1 3/8"-18 male thread coupling. All models feature triple cable entries with duplicated terminals. A large termination chamber and a threaded flameproof joint on the cover simplify installation and routine maintenance.

Features

• Multiple transformer tappings (25/70/100V options)
• Ratchet-adjustable 316 stainless steel mounting bracket
• Triple cable entries and duplicated cable terminations
• Robust marine-grade aluminium enclosure with chromate & powder coat finish (ISO 12944-6)
• UL 1480 and CAN/ULC-S541 fire alarm & signaling speaker listings
