If looking to apply power (complete the circuit): NO of the DS150 to the Positive of the Maglock. From the negative of the Maglock to the negative of the power supply. From the Positive of the power supply to Common on the DS150.   If looking to remove power (break the circuit): NC of the DS150 to the Positive of the Maglock. From the negative of the Maglock to the negative of the power supply. From the Positive of the power supply to Common on the DS150.   Note: Generally we do fail safe not fail secure and the relay timer needs to be incremented. ... View more

If there is no G in the panel's name, there is no ground fault detection and the panel does not have an S4 pin. If it has a single G in the name it has the chance it could be enabled if S4 is latched and under area 5 silent alarm relay there is a value other than 0. If it’s a GV2, GV3 or GV4 and S4 is latched, ground fault detection is enabled. If there is ground fault detection, latch S4 and measure DC voltage on Terminals 9 and 10: You should get 6.5-6.8 VDC Steady (not jumping around) when there isn't a ground fault. If there is a ground fault it can take up to a minute to display and clear at the keypad. ... View more

Test Reports can be set up from Teraterm or RPS (requires firmware 2.0 or above). The test report timer (re)starts when the panel item is changed or when the module reboots, once the timer expires the test report is sent. Step-by-step guide   Teraterm/RPS: Go to System Configuration > Test Report Settings > Test Report Interval The timer options are  Off, 4hr, 6hr, 12hr, or 24h ... View more

  Cause:   When the B420 or B426 has been programmed through the web interface and the setting; Panel Programming Enable has been set to NO, the B420 or B426 Ethernet Communicator module programming screen will look as displayed below with programming parameters not available for changing.   Solution:   The card will need to be accessed again through the web interface and Panel Programming Enable must be changed to read YES. Log into the Web-Browser and select Maintenance. Click on the drop-down arrow beside the field: Panel Programming Enable  and change it to Yes. When programming the B420 or B426 to be connected to a GV3 or older panel the web interface is used. When programming the B420 or B426 to be connected to a GV4 panel, use keypad programming. ...

You can use the Advantech ADAM-4541 Fiber Optic Converter to connect SDI2 devices via fiber optic cabling. Using fiber optic cabling allows you to extend the distance between SDI2 devices. Do not include the length of the fiber cabling in your wire length calculations for the SDI2 bus. Building-to-building SDI2 connections of SDI2 devices such as keypads, access control modules, power supplies, wireless receivers, input modules, and output modules are easily made. Notice: Use of the Advantech ADAM-4541 Fiber Optic Converter and SDI2 devices has not been investigated by Underwriter’s Laboratories. Do not use for UL applications or applications that include fire alarm components.   Products affected B9512/B8512 Control Panels B5512/B4512/B3512 Control Panels D9412GV4/D7412GV4/D7212GV4 Control Panels B520 Auxiliary Power Supply Module SDI2 Devices (Keypads and Modules)   Step-by-step guide   Install the ADAM-4541 Read the instructions provided with the ADAM-4541 before beginning the installation. You must provide power for the converters at both ends of the fiber cabling. The converter on the control panel end of the fiber cabling can be powered by the control panel or a B520 Auxiliary Power Supply Module (or other auxiliary power supply). The converter on the remote end of the fiber cabling must be powered by a B520 Auxiliary Power Supply Module (or other auxiliary power supply). The B520 is a fully supervised power supply and communicates its status to the control panel via SDI2 bus. The B520 allows you to power both the converter and SDI2 devices. Connect the data wires of the SDI2 bus to TX- (Green) and TX+ (Yellow).   Configure the ADAM-451 1 Set the ADAM-4541 Baud Rate (SW2) to 115,200 by setting Switch 8 to ON. Set the ADAM-4541 Operation Mode (SW3) to Normal by setting Switch 1 and 2 to OFF. Set the ADAM-4541 Data Format (SW1) to 11 bit by setting Switch 1 to OFF and Switch 2 to ON. ... View more
