LAMP (12-13):
• Provides fused power (1.85A max) to drive a flashing warning lamp to indicate gate operation.
• This output is active when the gate is operating (Opening and Closing).
• Lamp Delay sets the amount of time the lamp accessory output is activated prior to gate movement. Settings
from 0 to 5 seconds with a step of 0.5 seconds.
PIN 12 = LAMP
PIN 13 = GND (Ground)
ALARM (14-15):
• Provides fused power (0.5A @ 12VDC) to drive an alarm siren to signal the occurrence of a hard shutdown,
caused by 2 consecutive entrapment events (signals).
• This alarm output is reset by pressing the "Reset Hard Shutdown" button on the front panel or activating the
"FIRE" input.
PIN 14 = ALARM
PIN 15 = GND (Ground)
24VDC POWER OUTPUT (20-21):
• This power output is located along the lower strip of input connectors at pins 20 and 21.
• Pin 20 outputs a +24 Volts DC current, which is regulated and turns off when the control board goes into sleep
mode (power saving mode).
• This output may be used to power accessories that are required to power-down when board enters power
saving mode. This is primarily beneficial for solar powered configurations where it is desirable to reduce
power consumption.
PIN 20 = +24VDC Regulated
PIN 21 = GND (Ground)
