DESCRIPTION
The DMP 505 Series Power Supplies
are regulated, power limited,
switching power supplies. They
are rated for 12 VDC at 5 Amps

Each power supply includes a
transformer, battery leads and is
mounted in an enclosure. The 505
Series power supply also provides
connections for AC input, DC
output, and a standby battery.
Each power supply also includes a
low AC input LED indicator, a low
standby battery LED indicator, AC
trouble and battery trouble relays,
and on‑board transient protection
for the AC input and the DC output.
The 505‑12LX includes two Model
867 Style W Notification Modules.
Compatibility

MOUNT THE ENCLOSURE
Mount the power supply metal enclosure in a secure, dry location
to protect the unit from damage due to tampering or the
elements. It is not necessary to remove the PCB or transformer
when installing the enclosure.
Mount Optional NAC Modules
The power supply enclosure can accommodate two NAC modules
for powering various listed notification appliances. Use either the
DMP Model 865 conventional Class A NAC module, the Model 866
conventional Class B NAC module, or the Model 867 LX‑Bus NAC
module. Install any of the modules inside the enclosure using the
3‑hole mounting configuration. Plastic standoffs are provided with
each module that attach to the enclosure.
To mount a NAC module in a DMP enclosure, complete the
following steps:
1. Mount the plastic standoffs to the enclosure using the three
included Phillips head screws.
2. Insert the screws through the holes on the enclosure
exterior side and into the plastic standoffs which mount on
the enclosure inside. Tighten the screws into place and snap
the NAC module onto the standoffs.

WIRE THE 505 SERIES POWER SUPPLY
Refer to Figure 2, 3, and 4 for wiring details. Refer to 505 Series
standalone wiring diagrams LT‑0454 and LT‑0849 for specific
wiring applications.
Caution: Be sure to observe polarity when connecting wires to
avoid risk of personal injury and equipment damage.
Connect AC Power
Connect the transformer to an unswitched 120 VAC 60 Hz
power source with at least 1.5 Amps of available current. Start by
connecting AC power to the black and white transformer leads,
then connect AC power to the terminal block. Be sure to secure
the green wire lead to an earth ground.
Connect Batteries
Connect the black battery lead to the negative battery terminal
and the red battery lead to the positive battery terminal. Only
use sealed lead‑acid batteries and replace every 3 to 5 years. For
information about calculating standby battery power, refer to
Additional Information.
Connect AC and Battery Trouble Relays
Connect AC TRBL and BATT TRBL supervisory relay outputs
marked NC (normally closed) and C (common) to a control panel
or an 867 NAC zone.
Connect DC Output
Measure and verify output voltage before connecting devices to
ensure proper equipment operation. Connect devices that require
power to output terminals marked ‑ DC +.
