Section 1 Overview of D Series Smoke and Heat Detectors

The D Series family of detectors is comprised of a variety of detection technologies to meet
the needs of the fire protection community. The detectors are constructed of a white,
high-impact polymer. All detectors plug into DB-M01mounting base. The table below lists
the available detector models.

D Series Smoke and Heat Detectors Model Description

D series of smoke and heat detectors contain their own microprocessors which allow them
to make alarm decisions based on the information collected by their sensors. Depending on
the detector, decisions may be based on the information gathered by up to two independent
sensing elements.

DI-M9103/M9102/M9101 are intelligent addressable devices. The addressing is electronic
and can be configured using a hand held tool P-9910B, refer to the P-9910B programmer
operation manual for detail information. DC-M9103/M9102/M9101 are conventional
devices.

The D series detectors provide a red LED indicate the detector’s condition. The LED
indicator displays the following states:
DI-M9101,DI-M9102 and DI-M9103:

• Normal: Red LED flashing or off, modified by the hand held tool P-9910B

• Alarm/active: Red LED steady

DC-M9101, DC-M9102 and DC-M9103:

• Normal: Red LED flashing • Alarm/active: Red LED steady

Multiple sensing technologies are incorporated into DI/DC-M9101detectors, which makes
them suitable for a wide range of applications. The tables Smoke Detector Application
section of this document list the applications suitable for the DI/DC-M9101.

Section 2 Heat Detector Applications

WARNING: These detectors are intended for use with ionization and/or photoelectric smoke

detectors. A heat detector by itself does not provide life safety protection.
Heat detectors sense change in air temperature and initiate alarm conditions based on a

fixed-temperature point, rate of temperature rise, or amount of temperature rise above
ambient condition. Spot type heat detectors should be selected so that the rating is at least
20o F (11o C) above maximum expected ceiling temperature. Ceiling height, construction,
and ventilation play significant roles in detector performance and must be considered when
determining detector placement. The operating temperature range is 32℉to 100℉(0℃ to

37.8℃)。

2.1 Spacing of Heat Detectors

Spot type heat detector spacing ratings are based on detector installation on a flat smooth
ceiling that is 10 feet (3m) high. The listed spacing equates detector operation with the
opening of a standard sprinkler head within 2 minutes (+/- 10 seconds) located 10 feet (3m)
from the same fire. Spot type detector spacing is shown in the figure below. Detector
coverage is typically represented as a square because most structures have flat sidewalls.
Actual detector coverage covers a circle whose radius is 0.7 times the listed spacing. Since

all of the area within the detector’s circle of coverage is suitable for detecting a fire, the

shape and dimensions of the detector coverage “square” in the figure below may be

modified. Note that, although the coverage “square” is now a “rectangle,” the coverage area

remains within the overall detector circle of coverage.

A spot type heat detector will cover all points located within 0.7 times the listed spacing. The
listed spacing for heat detectors is S = 50 ft. (15.3 m).

Figure 3: Alternative heat detector coverage configurations

When installed on the ceiling, spot type heat detectors must be located a minimum of 4 in.
(10 cm) from side walls. When installed on side walls, the detector must be between 4 in. (10
cm) and 12 in. (30 cm) from the ceiling, as shown below.
