System Sensor 2151E Instrucciones De Instalación Y Mantenimiento

INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR MODEL 2151E
LOW PROFILE PHOTOELECTRONIC SMOKE DETECTOR
Before installing detectors, please thoroughly read System Sensor's Guide to conventional fire systems which provides detailed information on
detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are available at no charge from System Sensor.
GENERAL DESCRIPTION
Model 2151E photoelectronic detectors use state-of-the-art optical sensing chambers. These detectors are designed to provide open area
protection and to be used with compatible control panels only. The ability to plug these detectors into a variety of base options extends panel
compatibility and application flexibility.
0
Two LEDs on each detector light to provide a local 360 visible alarm indication. These detectors also have a latching alarm feature. The alarm
can be reset only by a momentary power interruption. These detectors may be tested by activating an internal reed switch with a magnet.

COVERAGE
As a general guide, the 2151E smoke detector should provide adequate protection of an area 70-90m
significant air movement. Where installation conditions or response requirements vary, different spacing may be necessary. It is essential to
consult local codes of practice for the installation of fire alarm systems before installing smoke detectors.
BASE SELECTION AND WIRING GUIDE
Refer to the installation instructions supplied with the plug-in detector bases for wiring details. System Sensor has a variety of detector bases
available for this smoke detector, including standard 2-wire with or without current limiting resistors or schottky diode or changeover relay.
All bases are provided with screw terminals for power and remote indicator connections and relay contact connections, if applicable. The
electrical ratings for each detector-base combination are also included in the base installation instructions.
INSTALLATION
NOTE: All wiring must conform to applicable local and national codes and regulations.
Verify that all detector bases are installed, that the detector monitoring circuits have been tested and that the wiring is correct. (Refer to
detector base instructions for testing procedure)
Remove power from detector monitoring circuits before installing detectors.
Install Detectors
1. Place the detector into the detector base.
2. Rotate the detector clockwise with gentle pressure until the detector drops into place.
3. Continue rotating the detector clockwise to lock it in place.
4. After all detectors have been installed, apply power to the detector monitoring circuits.
5. Test the detector as described under TESTING.
6. Reset the detector at the system control panel.
Tamper-Resistance
The detector bases include a feature that, when activated, prevents removal of the detector without the use of a tool. See the installation
instructions for the detector base for details of how to use this feature.
Dust covers are fitted to the detectors to help protect units during shipment and when first installed. They are not intended to
provide complete protection against contamination, therefore detectors 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.

TESTING
Detectors 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.
Test the detector as follows:
Test Magnet (Model M02-24 - optional)
1. Test the detector by positioning the test magnet against the detector body approximately 2 cm from LED1 in the direction of the metering
socket (see Figure 1).
2. Both LEDs should latch on within 30 seconds, indicating an alarm and activating the panel.
Calibrated Sensitivity Test (MOD400R)
1. Use the MOD400R Test Module with a digital or analogue voltmeter to check detector sensitivity as described in the test module manual.
After completion of all tests notify the proper authorities that the system is operational.
Detectors that fail these tests should be cleaned as described under MAINTENANCE and re-tested. If the detectors still fail these tests they
should be returned for repair.
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 detector to be cleaned from the system.
2. Remove the detector cover. 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. Remove the chamber cover by pulling it gently away from the sensing chamber until it snaps out of place.
6. Use a vacuum cleaner and/or clean, compressed air to remove dust and debris from the sensing chamber and sensing chamber cover.
7. Re-install the sensing chamber cover by aligning the arrow moulded on the cover with the arrow printed on the circuit board and sliding the
cover over the chamber, gently pressing it home until it until it snaps into place.
8. Re-install or replace the sensing chamber screen by sliding it over the sensing chamber. Rotate the screen until the locating tabs on the
bottom rim locate in the cutouts in the chamber base, and the top of the screen is flush with the top of the chamber.
9. Reinstall the detector cover. Use the test module socket and LEDs to align the cover with the sensor assembly. Snap the cover into place
making sure all tabs are engaged.
10. When all sensors have been cleaned, restore power to the loop and test the sensor(s) as described under TESTING.
WARNING - 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. 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.
