INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR
MODEL 1700EC ANALOGUE ADDRESSABLE IONISATION SENSORS
Before installing the sensor, please thoroughly read System Sensor's wiring and installation manual, I56-407-XX, Guide for Proper Use of System
Smoke Detectors . This manual includes detailed information on sensor spacing, placement, zoning, and special applications. Copies of this
manual are available at no charge from Ademco.
GENERAL DESCRIPTION
Model 1700EC analogue addressable ionisation sensors use state-of-the-art sensing chambers coupled with high standards of reliability to
provide early warning of developing fires . These sensors are designed for open area protection and must only be connected to control panels that
use a compatible proprietary analogue addressable communication protocol for monitoring and control.
Two LEDs on each sensor light to provide a local 360 0 visible sensor indication. The LEDs can be latched on by code command from the control
panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code command. Remote LED indicator capability is
available as an optional accessory wired to the standard base terminals.

WIRING GUIDE
Refer to the installation instructions supplied with the plug-in sensor bases for wiring details. All bases are provided with terminals for power and
an optional Remote Indicator.
NOTE: All wiring must conform to applicable local and national codes and regulations.
NOTE: Verify that all sensor bases are installed and that polarity of the wiring is correct at each base.
Disconnect loop power before installing sensors.
1. Sensor Installation
a. Set the sensor address (see Figure 3) by using a flat blade screwdriver to turn the two rotary switches, selecting the desired number between
01 and 99. Record the address on the label attached to the base.
b. Insert the sensor into the base and rotate it clockwise with gentle pressure until it drops into place.
c. Continue to rotate the sensor until it locks into the base.
2. Tamper-Resistance
Model 1700EC includes a feature that, when activated, prevents removal of the sensor without the use of tool. Refer to the installation
instructions for the sensor base for details of how to use this feature.
3. After all sensors have been installed, apply power to the system.
4. Test the sensor as described under TESTING.
5. Reset the sensor by communication command from the panel.
Dust covers help to protect units during shipment and when first installed. They are not intended to provide complete protection
against contamination therefore sensors should be removed before beginning construction, major re-decoration or other dust producing
activity. Dust covers must be removed before the system can be made operational.
MAINTENANCE
Before cleaning, notify the proper authorities that the system is undergoing maintenance and will be temporarily out of service. Disable the system
to prevent unwanted alarms.
1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover. (Note: Regulations in some countries may prohibit this operation on ionisation type sensors). Use a small flat
blade screwdriver to gently release each of the four cover removal tabs that hold the cover in place (see Figure 2).
3. Vacuum the outside of the screen carefully without removing it.
4. Remove the sensor screen. Pull the screen straight away from the sensing chamber until it snaps out of place. Replacement screens are
available.
5. Use a vacuum cleaner and/or clean, compressed air to remove dust and debris from the sensing chamber.
6. Reinstall or replace the sensing chamber screen by sliding the edge without the tabs over the sensing chamber. Make sure that one of the
screen contacts engages with the circuit board contact.
7. Reinstall the sensor cover. Use the test module socket and LEDs to align the cover with the sensor. Snap the cover into place.
8. When all sensors have been cleaned, restore power to the loop and test the sensor(s) as described under testing.

TESTING
Sensors must be tested after installation and following periodic maintenance. However,
before testing, notify the proper authorities that the smoke detector system is undergoing
maintenance and the system will be temporarily out of service. Disable the zone or system
undergoing maintenance to prevent unwanted alarms.
In addition, check to ensure that the LEDs blink (if this feature is operational under software
command). If they do not, power has been lost to the sensor (check the wiring), if it is
defective (return it for repair).
Test the sensors as follows:
A. Test Magnet (Model M02-24 - optional)
1. Test the sensor by positioning the test magnet against the sensor body approximately 2cm from LED1 in the direction of the metering
socket, as shown in Figure 1.
2. Both LEDs should latch on within 30 seconds, indicating an alarm and activating the panel.
B. Calibrated Sensitivity Test (MOD400R)
1. Use the MOD400R Test Module with a digital or analogue voltmeter to test calibrated sensor sensitivity as described in the test module
manual.
After completion of all tests notify the proper authorities that the system is operational.
Sensors that fail these tests should be cleaned as described under MAINTENANCE and retested. If the sensors still fail these tests they
should be returned for repair.

LIMITATIONS OF SMOKE DETECTORS
This smoke detector is designed to activate and initiate emergency action, but will do so only when used in conjunction with other equipment.
Smoke detectors will not work without power.
Smoke detectors will not sense fires which start where smoke does not reach the detectors. Smoke from fires in chimneys, in walls, on
roofs, or on the other side of closed doors may not reach the smoke detector and trigger the unit.
A detector may not detect a fire developing on another level of a building. For this reason, detectors should be located on every level of a
building.
Smoke detectors also have sensing limitations. Ionisation detectors offer broad range fire-sensing capability, but they are better at detecting
fast, flaming fires than slow, smouldering fires. Photoelectronic detectors sense smouldering fires better than flaming fires. Because fires develop
in different ways, and are often unpredictable in their growth, neither type of detector is necessarily better and a given detector may not always
provide warning of a fire. In general, detectors can not be expected to provide warnings for fires resulting from inadequate fire protection
practices, violent explosions, escaping gas, improper storage of flammable liquids like cleaning solvents, other safety hazards, or arson. Smoke
detectors used in high air velocity conditions may fail to alarm due to dilution of smoke densities created by such frequent and rapid air exchanges.
Additionally, high air velocity environments may create increased dust contamination, demanding more frequent maintenance.
Smoke detectors cannot last forever. Smoke detectors contain electronic parts. Even though detectors are made to last over 10 years, any of
these parts could fail at any time. Therefore, test your smoke detector system at least semiannually. Clean and take care of your smoke detectors
regularly. Taking care of the fire detection system you have installed will significantly reduce your liability risks.
