D7024 Reference Guide
9.0 Installation Guide for U.L. Listed Systems
9.1 D7024 U.L. Listings
The D7024 is U.L. Listed for the following:
• Commercial Fire Alarm (Type Service: Local,
Central Station, and Remote Station; Type Initiating:
Automatic, Manual, Sprinkler Supervisory, and
Waterflow), U.L. Standard UL864.
The control panel should be installed in accordance with
NFPA 72 for Commercial Fire installations.
9.2 Installation Considerations
• Failure to install and program the control in accor-
dance with the requirements in this section voids
the listing mark of Underwriters Laboratories, Inc.
• The standby battery capacity is 35 AH @ 24 VDC.
• The total nominal current must not exceed 970 mA
in standby nor 4 A when in alarm.
• The control must be mounted indoors and within the
protected area.
• Grounding must be in accordance with article 250 of
the NEC (NFPA 70).
• Zones must be connected to U.L. Listed, compatible
devices.
• The ground wire provided with the enclosure must
be connected between the door and the enclosure
using the supplied nuts.
• The ground start feature shall not be programmed.
• Phone monitoring must be selected if the DACT
(Digital Alarm Communicator Transmitter) feature is
used.
9.3 Programming the D7024
When used in U.L. Listed installations, the control must
conform to certain programming requirements. The
following is a list of the required program entries and
required accessories for specific U.L. Listed installations.
Commercial Fire Alarm (Central Station (DACT) and
Local)
Required Accessories:
• At least one Radionics, Inc. Model D285 smoke
detector with a D287, D288, D292, or D293 Series
base; or another Listed compatible smoke detector.
• At least one Radionics D601S horn/strobe or D443
bell (will provide 85 db for UL985 and NFPA 72
requirements; other Listed compatible devices with
a voltage range of 20 to 31 V may be used) is
required for this application and must be installed
inside the protected area.
• Four-wire detectors must be used with Listed power
supervision devices. A compatible Listed 4-wire
detector is the Radionics, Inc. D285 in a D292 or
D293 Series base. A compatible Listed EOL relay is
the Radionics, Inc. D275.
• All points must be used with the EOL resistor
provided.
A. Report Programming:
• Non-supervisory and supervisory reports must be
programmed for those points used.
• Trouble reports must be programmed.
• AC failure report delay must be set for 75% of
estimated standby time, or set to report at 25% of
battery capacity.
• Automatic test report frequency must be set at
least every 24 hours.
B. Timer Programming:
• Autosilence time must be programmed for not less
than 5 minutes.
C. Point Programming:
• For fire points: open = trouble, latching.
D. Alarm Output Programming:
• Notification Appliance Circuits must be pro-
grammed to activate from the appropriate input
points.
E. Communications Programming (if Used for Central
Station Service):
• Central Station report/monitor must be enabled.
• Monitoring of both phone lines must be enabled.
9.4 Reversing Modules
A. D132:
The D132 Smoke Detector Reversing Relay Module
allows the D7024 Control/Communicator to sound all
smoke detectors connected to Point 1 when a single
detector on the loop goes into alarm. To restore the
detectors to normal, reset the sensors.
B. D185:
The D185 Reverse Polarity Module is a UL Listed
module that connects the control panel with either a
single set or a pair of leased Telephone Company
(Telco) lines in NFPA 72 remote station applications. It
relays system alarm status information from the panel
to a monitoring station. The D185 operates with either
12 or 24VDC supply.
