Input conditions
*1
*1. The input terminal is pulled up to +15 V supply voltage by resistor. Opening of the input terminals is equivalent to
a high level input.
• High level input voltage 11 V to 15 V
• Low level input voltage 0 V to 4 V
• Low level sweep out current 5 mA or less
• Input pulse width 20 ms minimum
Interlock Protection is effected when INTERLOCK terminal is made open
(test is disabled).
Output signals
*2
*2. The rating of the signal contacts is 125 VAC, 1 A, or 30 VDC, 1 A.
Loudness of the buzzer is adjustable with a knob in common for the PASS signal and FAIL alarm.
