AES 7707 RF Subscriber 42
Part No. 40-7707 Rev. 3a 10/23/2017
 DC Report Delay: DC Report Delay is active when Suppress DC Power Fault is set to No. The
report delay is the time that must pass before the Model 7707 Subscriber will send a primary power
failure or primary restoral message. This feature helps prevent mesh network congestion in an area
where many subscribers have a power outage at the same time. Messages can be set to transmit in a
staggered fashion using the Random time setting.
Note: Primary power (24 V DC) failure fault reporting must be enabled for compliance with UL-864
standard in fire installations.
The combined DC fail detection time delay of 100 minutes plus the random DC Report Delay between 0‒
60 minutes results in time that does not exceed 160 minutes. This is within the UL-864 requirement of
reporting DC power failure within 180 minutes (3 hours) of loss.
Primary (24 V DC) power must be lost for 100 minutes in order to be reported as a failure. Primary (24 V
DC) power must be restored for at least 100 minutes to be reported as a restore. Once either is detected, a
message is created by the Subscriber to send to the central station. A DC Report Delay is selected based on
this parameter and the setting of Suppress DC Fault reporting. Available settings:
─ Random Delay ─ A random time ranging from 0‒60 minutes after 100 minutes of primary (24 V
DC) power loss. Enter R in the box to select this option.
─ Fixed Delay ─ A specific time ranging from 1‒60 minutes after 100 minutes of primary (24 V DC)
power loss.
─ No Delay ─ Immediate transmission after 100 minutes of primary (24 V DC) power loss.
 Locally Announce DC Fault
Important! UL-864 compliant Fire Alarm installations require Locally Announce DC Fault to be set to
Yes. See the Programming Options (UL Notice to Users) on page 23 for software settings permitted for the
following parameter.
Set Locally Announce DC Fault to Yes/No by clicking the Locally Announce DC Fault switch.
 Suppress DC Power Fault
Important! UL-864 compliant Fire Alarm installations require Suppress DC Power Fault to be set to
No. See the Programming Options (UL Notice to Users) which starts on page 23 for software settings
permitted for the following parameter.
Set Suppress DC Power Fault to Yes/No by clicking the Suppress DC Power Fault switch.
 Suppress Battery Fault Reporting
Important! UL-864 compliant Fire Alarm installations require Suppress Battery Fault Reporting to be
set to No. See the Programming Options (UL Notice to Users) which on page 23 for software settings
permitted for the following parameter.
 Suppress Charger Fault Reporting
Important! UL-864 compliant Fire Alarm installations require Suppress Charger Fault Reporting to be
set to No. See the Programming Options (UL Notice to Users) which starts on page 23 for software settings
permitted for the following parameter.
Set Suppress DC Power Fault to Yes/No by clicking the Suppress Charger Fault Reporting switch.
 Power From: 24 V DC Only
Refer to the diagram shown in the Power Options section on page 10 for supply and connection
requirements.
Note: Selecting the 24 V DC only option causes Suppress Battery Fault and Suppress Charger Fault to
