An AGD electrical leakage fire alarm.[Features]· An updated version of a long-selling product with a 30-year track record.· The basic functions are maintained but with greater compactness.· The surface type maintains the same mounting dimensions but has been more compact. The square bodied embedded type has approximately half the volume ratio as previous models (excluding the AGD-U2).· The built-in digital filter reduces the effects of high-frequency noise, allowing more precise monitoring of electrical leakage.· The output contact configuration is 1c+1a × the number of monitoring circuits. This enables remote monitoring via external signal contacts, and an alarm output for each monitoring circuit.· Even the square bodied embedded types come equipped with built-in buzzers (excluding the AGD-U2).· Can also output an alarm to any external buzzer.· All updated products are available with either automatic or manual recovery AGD-N5, AGD-NY5, and AGD-N52).
