Transient clamping must be provided to protect the output contacts and to reduce EMI emissions. For AC- powered devices, use MOV across the load. For DC-powered devices, use a diode across the load.Relay Contact (DC Strike)12 VDCDC STRIKE+ -NCC NONONC+CDIODE 1N4002 (100V/1A) TYPICAL DIODE CURRENT RATING > 1X STRIKE CURRENT DIODE BREAK DOW N VOLTAGE > 4X STRIKE VOLTAGE330 — revision 6Hardware Installation GuideRelay Contact (AC Strike)AC XFMRAC STRIKENCC NONONCCFOR 24 VAC STRIKE, PANASONIC ERZ-C07DK470 MOV SELECTION: CLAMP VOLTAGE > 1.5 X VAC RMS62.1.4Downstream Reader CommunicationThe Single Reader Interface Module can communicate downstream with one (1) keypad or card reader. The J1 interface is a six-wire interface that includes a buzzer control wire and an LED control wire. The buzzer wire is an open collector that produces 5 VDC open circuit maximum, and 10 mA sink maximum. The LED wire provides between 0.05 and 3 V, 5 mA source/sink maximum.
