Before Installing
This detector must be installed in compliance with the control 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 photoelectric, 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. EDDP 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 detector 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 addressable communications to function properly. Connect these
detectors to listed-compatible control panels only.
apart. For specific information regarding detector spacing,
placement, and special applications, refer to NFPA 72 or
the System Smoke Detector Applications Guide, available
from System Sensor.
Duct Applications: ED-P and ED-PT are listed for use in
ducts. See Duct Applications Guide A05-1004-XX for details
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 wiring 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.
Spacing
System Sensor recommends spacing detectors in compliance with NFPA 72. In low air flow applications with
smooth ceilings, the detectors should be spaced 30 feet

B.Smoke Entry:
Smoke entry testing should be performed immediately
following the functional test. The functional test initiates
an approximately 5 minute period when the detector’s
signal processing software routines are not active. Failure
to do so will introduce a time delay before the detector
alarms.
CAUTION
Dust covers provide limited protection against airborne dust
particles during shipping. Dust covers must be removed
before the detectors can sense smoke. Remove detectors
prior to heavy remodeling or construction.
Tamper-Resistance
Models ED-P and ED-PT include a tamper-resistant capability that prevents their removal from the base without the
use of a tool. Refer to the base manual for details on making use of this capability.
Home Safeguard Model 25S Smoke Detector Tester can
be used to verify smoke entry into the sensing chamber
and the corresponding alarm response. Aim the aerosol
can at the detector and spray for one to two seconds from
a distance of two to four feet until the panel alarms.
Testing
Before testing, notify the proper authorities that the system
is undergoing maintenance, and will temporarily be out of
service. Disable the system to prevent unwanted alarms.
Another method is to use the GEMINI model 501 aerosol
generator for smoke entry testing. Set the generator to
represent 4%/ft. to 5%/ft. obscuration as described in
the GEMINI 501 manual. Using the bowl shaped applicator, apply aerosol until the panel alarms.
All detectors must be tested after installation and periodically thereafter. Testing methods must satisfy the Authority
Having Jurisdiction (AHJ). Detectors offer maximum performance when tested and maintained in compliance with
NFPA 72.
C. Direct Heat (ED-PT only):
A hair dryer, heat gun, or test apparatus designed for this
purpose should be used to test the thermistors. Direct
the heat toward either of the two thermistors, using care
to avoid damaging the plastic housing. The detector will
reset only after it has had sufficient time to cool. Make
sure that both thermistors are tested individually.
A detector that fails any of these tests should be cleaned
as described under CLEANING, and retested. If the
detector fails after cleaning, it must be replaced.
The detector can be tested in the following ways:
A.Functional:
This detector can be functionally tested by using the
EA–CT. Following the instructions, initiate the detector
test sequence. The detector will then send a test alarm
message to the panel. Refer to the control panel technical documentation for further information.
When testing is complete, restore the system to normal operation and notify the proper authorities that the
system is back in operation.

Cleaning
Before removing the detector, notify the proper authorities
that the smoke detector system is undergoing maintenance
and will be temporarily out of service. Disable the zone
or system undergoing maintenance to prevent unwanted
alarms.

Cover
1. Remove the detector to be cleaned from the system.
2. Remove the detector cover by pressing firmly on each
of the four removal tabs that hold the cover in place.
3. Vacuum the screen carefully without removing it. If
further cleaning is required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or clean compressed air to
remove dust and debris from the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the sensing chamber. Turn until it is
firmly in place.
7. Replace the cover using the LEDs to align the cover
and then gently pushing it until it locks into place.
Make sure that the thermistors do not become bent
under the cover on ED-PT models.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back
on line.
