Digital Monitoring Products Inc PC0086 Manual De Usuario

The 7075 keypad provides one internal Form C single pole, double throw (SPDT) relay for controlling door strikes 

or magnetic locks.  Three wires on the 5-wire harness, Violet (N/C), Gray (Com), and Orange (N/O), allow you 

to connect devices to the relay.  The Form C relay draws up to 30mA of current and its contacts are rated for a 

maximum of 1 Amp at 30 VDC.
Note: For UL installations, the door strike relay must be connected to devices within the same room.
Wiring the 333 Suppressor 
One Model 333 Suppressor is included with the 7075 Keypad.  Refer to Figure 3 and install the suppressor across the 

5-wire output/reader harness Common (C) and Normally Open (NO) or Normally Closed (NC).   
If the device being controlled by the relay is connected to the NO and C terminals, install the suppressor on the NO 

and C terminals.  Conversely, if the device is connected to the NC and C terminals, install the 333 Suppressor on NC 

and C terminals.

7075 Door Strike Relay Operation
As soon as the user code sent from the reader is verified by the panel, the keypad Door Strike relay activates for five 

seconds.  During this time, the access door connected to zone 2 must be opened to start the 40-second entry/exit 

timer and zone soft shunt.  See the timeline shown below.
Note: The 5-second delay length is programmable when the keypad is used on an XR200-485 or XR500 Series panels.  
Refer to the XR500 Series Programming Guide (LT-0679) or the XR200-485 Programming Guide (LT-0196).

If the door being released by the keypad is protected, you can provide a 40-second shunt by connecting its contact 

to zone 2 (White/Red pair) on the keypad and enabling the Soft-Shunt feature.  See ZONE 2 SHUNT and Door Strike 

Relay Specifications in this document.  Once the door strike relay is activated, the user has 5 seconds to open the 

door connected to zone 2.  The zone is then shunted for 40 seconds.  Door contacts may be N/C or N/O.
