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).
3.
Install the mounting plate, insert the wiring, and pull
the wiring through the wire entrance.
