GDS3705 User Manual
Version 1.0.1.16
For above example, the GDS3705 is configured to control Door1 (wiring to COM2 interface); the 3
rd
party
Wiegand Input is set to control Door2 (wiring to COM1 interface).
In case of a power loss then the DOOR STATUS when power is off will be depending on the following
situations:
COM2 has three wiring PINs, corresponding to NO or NC accordingly. Therefor when connecting
NC2 and COM2 (Fail Safe) then strike will open when power is lost and when using a NO2 strike
(connecting COM2 and NO2) then door is “locked” when power is lost (Fail Secure).
COM1 (ALMOUT1) has only two PIN, and NO ONLY. If the connected strike/lock is a NO strike,
this means ALMOUT1 Status should be set to “Normal Open” then door will be closed when
power is lost, while if the strike connected is NC strike, and ALMOUT1 Status is set to “Normal
Close” then door will be open when power is lost.
Universal PIN for Operation of Doors:
Figure 42: Universal Local PIN
If Unified PIN (Universal PIN) is configured to open door, then which door can be controlled by the PIN is
configured in the UI once “Unified PIN” selected.
For example, like above screenshot, if this universal PIN is set to open both Door1 and Door2, but due to
previous “Control Option” set to open Door1, and “Wiegand Control” set to open Door2, therefore the final
result will be the INTERSECT result of both sets with condition qualified.
