Penton APH20T/ENC

The Penton APH20T/ENC EN54-24 compliant, weatherproof, lightweight re-entrant horn is rated at 20 Watts, 100 Volt line.

Good speech clarity makes this horn suitable for communication or warning signals.

These horns are ideal for marine and industrial use as they are non-corrosive and resistant to salt laden air.

Fitted, as standard, with 1 x PG9 gland but will open to 20mm + 1 x 20mm knockout allowing the installer to loop in & loop out the cabling without the need for an additional junction box.
