Before Installing
This detector must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Detectors offer maximum performance
when installed in compliance with the National Fire Protection Association
(NFPA); see NFPA 72.
Product Description
Model ED-TI is an intelligent, spot-type heat detector, designed to be program-
mable for a setpoint range of 135ºF to 174ºF for ordinary detection or 175ºF
to 190ºF for intermediate detection. Detectors in the ordinary range may be
programmed for either fixed or 15ºF rate of rise operation. Detectors set be-
tween 135ºF to 155ºF or 175ºF to 190ºF are designed 50 foot spacing. Detec-
tors set between 156ºF to 174ºF are designed for 15 foot spacing.
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 in-
dependently controlled. A remote LED annunciator is available as an accessory
(RA400Z). The detector has on-board short circuit isolators to prevent shorts on
the signaling line circuit from disabling all devices on the intelligent loop.
Wiring Guide
All wiring must be installed in compliance with the National Electrical Code,
applicable local codes and the Authority Having Jurisdiction. Proper wire
gauges should be used. The installation wires should be color coded to limit
wiring mistakes and ease 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).
4. Test the detector as described in the TESTING section of this manual.

Branch Markers
In order to determine the beginning of a branch, a branch marker can be
set at a particular device. The branch marker can be physical or electronic.
Electronic branch markers are set with the IR configuration tool, EA‑CT. An
electronic branch marker is a value from 0 to 255 stored in the device memory.
Physical branch markers are resistors that are wired from the detector remote
LED terminal to the (–) communication terminal.
There are five possible values:
Resistive Value
33k ohm
15k ohm
6.8k ohm
2.2k ohm

*A 100 ohm branch marker precludes the use of the RA400Z.
Tamper Resistance
The detector bases have a tamper-resistant capability. When this capability is
enabled, detector cannot be removed from the base without the use of a tool.
Refer to the detector base installation instruction manual for details in using
this capability.
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.
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.
B. Direct Heat:
A hair dryer, heat gun, or test apparatus designed for this purpose should
be used to test the sensing circuit. Direct the heat toward the thermistor,
using care to avoid dam-aging the plastic housing. The detector will reset
only after if has had sufficient time to cool.
Detectors that fail these tests should be cleaned as described under CLEAN-
ING and retested. If the detectors still fail these tests they should be returned
for repair.
Cleaning
NOTE: Before cleaning notify the proper authorities that the system is undergoing
maintenance, and therefore the system will temporarily be out of service. Disable
–
the loop or system undergoing maintenance to prevent unwanted alarms.

It is recommended that the detector be removed from its mounting base for
easier cleaning and that detectors be cleaned at least once a year. Use a vac-
C0360-00 ^{uum cleaner to remove dust from the sensing chamber.}
