Data Sheet

Summary Trouble Relay
The Summary Trouble Relay is used as a common
trouble indicator. Set the DIP switches to activate the
relay for one or more of the following trouble
conditions:
• AC Power Failure
• On-Board AC Fuse Failure
• Power Output Fault
• Battery Test Failure
• Battery Trouble: Low, Missing or Shorted
These trouble conditions can be individually identified
to the central station or grouped to activate the
Summary Trouble Relay.
Switched Output Control
A remote device can switch the power output on or off
with a 12 VDC trigger voltage or a dry contact closure.
Use this feature to remove power from devices or to
apply power to notification devices that require power
during a fire alarm such as horns, strobes and bells.
When used for notification appliances, the power
supply must be installed within 20 ft (6 m) of the
control unit and the trigger wire must be in conduit.
System Power
The power supply provides power to and receives low
voltage AC power back from the D1601 Transformer.
The power supply can also provide 16.5 VAC, 40 VA to
power the control panel. If the power supply is used to
power the control panel, mount the D8109L Enclosure
next to the control panel's enclosure and run the wire
through conduit.

Installation/configuration notes
Battery Requirements
The power supply uses two sealed lead acid batteries
connected in series to provide a 24 V of standby
power. Two batteries must be used. The power supply
does not provide standby power with only one battery
connected.
Notice
You must use sealed lead acid batteries: The
power supply is designed to charge only sealed
lead acid batteries. Using any other type of
battery might cause damage to the power supply
or the batteries.
Selecting the correct batteries for the system depends
on the total continuous current draw of all devices, the
amount of standby time required, the amount of
intermittent current draw (in alarm) needed, and
finally the time it takes to recharge the batteries. For
calculating standby power requirements, see the
D9142F Operation and Installation Guide.
Compatible Products
It is compatible with all Bosch Security System control
panels but only use it with a UL-Listed control panel
for fire alarm applications. For devices compatible
with the power supply, refer to the D9142F
Compatibility List).
Enclosure Information
The D8109L is a louvered version of the standard
D8109, UL‑Listed fire enclosure. It is supplied with the
standard D101F lock and key set. The D8109L is
designed to house the D9142M, the D1601
Transformer and the batteries. Standard sized
knockouts are provided for conduit connections.
Only use the D8109L Enclosure with the D9142M,
D9142LC, or D9142EXP Power Supplies. This
enclosure is designed to allow the air circulation
needed to keep the power supply cool. The enclosure
requires 0.5 in. (1.3 cm) clearance on all sides.
Mounting Considerations
Typically, the power supply is installed adjacent to the
control panel. To attach the enclosure to the wall, use
mounting hardware that is capable of supporting
55 lbs (25 kg) of equipment. You might need to mount
a plywood sheet to the wall in order to support the
weight of the power supply and batteries.
