Note: Devices that require power from the PS4085
shall be UL Listed for the intended application and
operation over the range 11.5-12.6VDC
Terminal Descriptions
AC - Supervised input. Connect the secondary of the transformer to these terminals. Connect the
primary of the transformer to a dedicated electrical circuit (commercial fire installations) or to an
unswitched AC source (other applications).
+12V/COM - Special applications output circuit, power limited. Connect to devices that require
power. Connect the positive lead of powered devices to the +12V terminal and the negative lead to the
COM terminal.
ACT - This open collector output activates when an AC Trouble is detected: Rated 50mA.
LBT - This open collector output activates when a Battery Trouble condition is detected: Rated 50mA.
TEST - This open collector output activates when the charging circuit is in a trouble condition: Rated
50mA. These outputs may be used to activate an indicating device, such as an LED, or a relay to
activate devices requiring more current. The terminals may also be connected to a control panel zone
input to generate an alarm and to have the system report trouble conditions.
To report AC failure and low battery conditions with individual reporting codes, connect the ACT and
LBT to individual alarm zones. The ACT and LBT terminals may also be connected to a single alarm
zone. When so connected, both trouble conditions are reported with a single reporting code.
+BAT/-BAT - Used to connect the standby battery, non-power limited. Use single or dual lead battery
wire assembly.
Battery Charge Current
Select the battery charge current using jumper “CON1”. To avoid damage to the battery, do not select
a battery charge rate greater than 0.1 times the battery AHr rating.
Jumper Setting Charge Current Battery Size
A-B 400mA 4Ah
B- C 700mA 7Ah, 14Ah
None Future Use N/A
Note: For UL Listed installations use only 700mA setting.
Applying Power
After all wiring is complete, connect the battery leads to the battery, then connect the AC trans-
former. For information on the power requirements of specific devices, refer to the instructions sup-
plied with the device.
IMPORTANT! Do not connect power until all wiring is complete.
Mounting the Cabinet
When mounting the cabinet, select a dry location within 1m/3.3ft of the control panel.
To mount the cabinet:
1. Press 4 white circuit board stand-offs into the raised mounting holes at the back of the cabinet.
2. Hold the cabinet in position and pull all wiring through the holes in the back.
3. Using the provided mounting screws and appropriate wall anchors, mount the cabinet securely to
the wall.
4. Press the PS4085 module onto the plastic stand-offs.
Enclosures
The PS4085 can be installed in the metal enclosure described below. Tamper protection switches can
be installed on all enclosures, including door opening protection and/or removal from the mounting pos-
ition. Doors can be secured using screws or keylock.
Internal and/or external wiring for this module shall be routed, supported, clamped or secured in a
manner that reduces the likelihood of the following:
• excessive strain on wire and on terminal connections.
• loosening of terminal connections.
• damage of conductor insulation.

FCC COMPLIANCE STATEMENT
CAUTION: Changes or modifications not expressly approved by Digital Security Controls could void
your authority to use this equipment.
This equipment generates and uses radio frequency energy and if not installed and used properly, in
strict accordance with the manufacturer’s instructions, may cause interference to radio and television
reception. It has been type tested and found to comply with the limits for Class B device in accord-
ance with the specifications in Subpart “B” of Part 15 of FCCRules, which are designed to provide
reasonable protection against such interference in any residential installation. How¬ever, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
inter¬ference to television or radio reception, which can be determined by turning the equipment off
and on, the user isencouraged to try to correct the interference by one or more of the following meas-
ures:
• Re-orient the receiving antenna
• Relocate the alarm control with respect to the receiver
• Move the alarm control away from the receiver
• Connect the alarm control into a different outlet so that alarm control and receiver are on different
circuits. If necessary, the user should consult the dealer or an experienced radio/television technician
for additional suggestions. The user may find the following booklet prepared by the FCC useful: “How
to Identify and Resolve Radio/Television Interference Problems”. This booklet is available from the
U.S. Government Printing Office, Washington D.C. 20402,Stock # 004-000-00345-4.
