If the DASAlert Panel is located close to the building’s Fire Panel (which has an audible alarm triggered by the DAS alarms) then the DASAlert buzzer can be permanently disabled by setting DIP switch SW-2 (switch 9) to the ON position. If the key is lost, contact Technical Support for alternative ways to silence the buzzer. -

Panel. • The length of the cables from the DAS equipment to the Panel is another variable. If the cables are shorter than 20 feet, then no End-of-Line Resistors (EOLR) are required by code to supervise the connections. - Page 10 Figure 3.

Page 14: Dip Switch Settings
DIP SWITCH SW2 (switches 1-8) are used to set the Alarm Detection mode for the signals from the dry relay contacts in the DAS equipment. If the relay closes (is shorted) when there is an alarm, set the switch OFF. If the alarm relay is normally closed (shorted), but is open when there is an alarm, turn the switch ON. - Page 15 Table 3. Factory Default DIP Switch Settings Table 4. Fire Panel Relays - 12 -...

AMAZON. Typically, the best practice is to replace them annually when the rest of the DAS is tested. For the backup batteries to operate, DC primary power must be on first. After that, the battery power will cut in automatically if primary DC power on J10 is lost. -
Page 17: Connections To Building's Fire Panel
Connections to Building’s Fire Panel (See Figure 7) The Fire Panel should be connected to J5, J12, J14 and J16 at the bottom of the panel’s main PC board. The connectors as shown will mate with the panel’s independent internal dry relays to signal alarms to the Fire Panel. -

Page 19: External Detection Of Donor Antenna Disconnection
Figure 8. Antenna Monitor Connection Diagram External Detection of Donor Antenna Disconnection UL-2524 requires that if the outdoor donor antenna is disconnected an alarm should be triggered. In the event that the BDA in use does not sense this condition to output an alarm relay closure, an external method using a bias-T can be configured as shown in Figure 8. -
