Before Installing
This detector must be installed in compliance with the con-
trol panel system installation manual. The installation must
meet the requirements of the Authority Having Jurisdiction
(AHJ). Detectors offer maximum performance when
installed in compliance with the National Fire Protection
Association (NFPA); see NFPA 72.
General Description
Models ED-P, ED-PT and ED-DP are intelligent photoelec-
tric, spot-type smoke detectors utilizing sensing chambers
that are designed to respond rapidly to a broad range of
fires. The sensing chamber employs features that minimize
the effects of settled dust on performance. Model ED-PT
uses a thermistor based, 135°F heat detection circuit in
addition to the photoelectric sensing chamber. ED-DP is
designed for use inside the ED-DPR duct housing only. ED-
DP should not be used in open area applications.
The detector is designed with tri-color LEDs to indicate
detector status. The detector can be programmed to make
the LEDs blink or be steady green, amber or red. The detec-
tor remote output can be configured to follow the LED or
be independently controlled. A remote LED annunciator is
available as an accessory (RA400Z).
The ED-P, ED-PT and ED-DP require compatible address-
able communications to function properly. Connect these
detectors to listed-compatible control panels only.
System Sensor recommends spacing detectors in compli-
ance with NFPA 72. In low air flow applications with
smooth ceilings, the detectors should be spaced 30 feet

available
from System Sensor.
Duct Applications: ED-P and ED-PT are listed for use in

on pendant mount applications.
Wiring Guide
All wiring must be installed in compliance with the
National Electrical Code, applicable local codes, and any
special requirements of the Authority Having Jurisdiction
(AHJ). Proper wire gauges should be used. The installation
wires should be color-coded to limit wiring mistakes and
simplify system troubleshooting. Improper connections will
prevent a system from responding properly in the event of
a fire.
1. Wire the detector base (supplied separately) per the wir-
ing diagram, see Figure 1.
2. Install the detector into the base. Push the detector
into the base while turning it clockwise to secure it in
place.
3. Set the desired address using the IR configuration tool
(model no. EA–CT).
Note: Maximum range for the EA–CT is 30 ft. (9 m).
4. Test the detector(s) as described in the TESTING section
of this manual.
