D263/D273 Series | Installation Instructions | 1.0 Overview
Notice
Install, test, and maintain the D263/D273 Series according
to these instructions, NFPA 72, Local Codes and the
authority having jurisdiction (AHJ). Failure to follow these
instructions can result in the detectors not operating
properly.
Bosch is not responsible for improperly
installed, tested, or maintained devices.
Follow the procedures in these instructions
to avoid personal injury or damage to
equipment.
NFPA 72 requires performing a complete
system-wide functional test following
modifications, repairs, upgrades, or
adjustments to the system’s components,
hardware, wiring, programming, software,
and firmware.
FCC Compliance
This device complies with Part 15 of the FCC Rules and the
RSS-210 of Industry and Science Canada.
Operation is subject to the following two conditions:
1. this device may not cause harmful interference, and
2. this device must accept any interference received,
including interference that may cause undesirable
operation.
Changes or modifications not expressly approved by Bosch
Security Systems can void the user’s authority to operate the
equipment.
1.0 Overview
These instructions cover the D263/D273 Series Photoelectric
Smoke Detector installations in a fire system supervised by a
Bosch fire alarm control panel (FACP).
The D263/D273 Series are UL Listed, open-area
detectors designed for use with commercial fire protective
signaling and household fire warning systems (refer to
NFPA 72).
For commercial and industrial installations, space the
detectors 30 ft (9.2 m) apart as recommended by
NFPA 72.
An LED indicator flashes approximately every 3.5 sec to
verify the detector has power and the smoke sampling
circuitry is functioning. The LED latches ON during an
alarm, allowing the user to easily verify individual
detector alarms. After you clear the alarm condition, reset
the detector by interrupting power.
The LED on the D273IS latches on during an alarm from
heat but not from smoke.
Power supervision requires an optional end-of-line (EOL)
power supervision device such as a D275, on the D273
Models without EOL relay, and an EOL resistor as specified
by the control panel manufacturer. The D273ES, D273THE
and D273THES have a built in EOL supervision relay and
can be used as an equivalent to the D275.

1. Remove the dust cover. The dust cover can be replaced
during construction periods, but it must be removed
after the alarm system is enabled.
2. Remove the detector from the mounting plate by
pressing the locking tab and twisting it
counterclockwise. If you do not want the locking tab,
break if off now (refer to Figure 2).
Install the mounting plate, insert the wiring, and pull

3.0 Wiring
Before connecting or disconnecting any
D263/D273 Series Detectors, remove all
The terminal block is removable. It might be easier to
remove the terminal block from the detector before making
the wire connections. Remove the terminal block by pulling
it back and then pulling up. Refer to Figures 3 through 8 on
pages 3 through 5 for wiring details.
When all wiring connections are made, connect the detector
to the mounting plate by twisting it clockwise into place.
AC and battery power from the FACP.
Failure to do so can result in personal injury
and damage to the equipment.
Refer to your control panel’s installation
instructions for EOL resistor selection.
