A basic, surface-mount internal speaker suitable for Grade 1 installations. Internals include a choc block pre-wired to the speaker for quick connections. 16 Ohm impedance, producing up to 92dB when driven at 12V.
Must be connected to a suitable speaker output on the receiving equipment – this unit will not operate with only 12V DC input like a piezo buzzer would.
For Grade 3, see part code I20 – or I40 for a dual-tone sounder.
