Note:
• Terminal blocks are “depluggable” for ease of wiring.
• All power limited circuits must use type FPL, FPLR, or FPLP power limited cable.
• Initiating circuits are fully supervised and rated for 22 VDC, 3 mA standby, 5 mV ripple, 50 mA max
alarm. They may be configured as required. The alarm threshold is 21 mA. Maximum loop resistance is
100 ohms, 50 ohms per side.
• All conventional hardwire initiating circuits are Compatibility ID "A".
