DSC WS4936EU User manual

Introduction
The WS4936 / WS4936EU / WS8936 is a wireless photoelectric smoke detector with a fixed tem-
perature and rate of rise heat detector, and an internal piezoelectric alarm. Three versions are
available: a 433MHz North American version (WS4936), 433MHz European/International and Aus-
tralian version (WS4936EU) and an 868MHz European version (WS8936).
NOTE: Heat detection based on rate of rise has not been investigated by cULus.
NOTE: AUS and EU versions do not include a fixed temperature heat alarm, but DO include a rate
of rise alarm.

HUSH/TEST BUTTON
Operation
Approximately every 7 to 8 seconds the unit tests for a smoke or heat alarm condition. During this
sequence the unit also performs self diagnostics, and checks for tampers and faults. During normal
operation the green LED will flash every 12 seconds and the sounder will not sound.
Smoke Alarm
The smoke detector will go into alarm when the signal level exceeds the “alarm” threshold and auto-
matically restore when the signal level falls below the alarm “restore” threshold. During an alarm
the LED will flash 1/second and the sounder will sound the evacuation temporal pattern.
Alarm Silencing
This smoke alarm is provided with an automatically resettable alarm silencing feature. When the
sensor is in alarm, by pressing the Test/Silence/Reset button it will silence the local annunciation of
the alarm and transmit an alarm restoral event to the control panel. The LED will flash every 8
seconds (for up to 10 minutes) to indicate the alarm has been silenced.
The flashing LED will stop when the unit returns to normal operation. The alarm silence feature has
a fixed time setting that desensitizes the smoke alarm for 8 minutes.
Alarm silencing does not disable the smoke alarm but rather reduces its smoke sensitivity. Fol-
lowing the silenced period the smoke alarm restores automatically to its intended operation. If
smoke around the unit is dense enough to suggest a potentially dangerous situation, it will stay in
alarm, or may return to the alarm state quickly.
Detector Trouble
When the detector has a general fault, the yellow LED blinks once every four seconds and there is
a chirp every 48 seconds. After 12 hours,the panel will display a loss of supervision message.

Detector Dirty Feature
When the detector has been contaminated, the yellow LED blinks once every 8 seconds and there
is a chirp every 48 seconds. Refer to the MAINTENANCE section for cleaning the detector. After 12
hours, the panel will display a loss of supervision message.
Heat Alarm
The heat detector (cULus versions only) will go into alarm when the heat signal level exceeds the
heat alarm threshold (135ºF/57ºC); and will automatically restore when the heat signal level falls
below the heat alarm threshold (restore). The detector will also go into heat alarm if there is a rapid
increase in the temperature over a short period of time. During an alarm the LED will flash 1/second
and the sounder will sound the evacuation temporal pattern.
Tamper
The removal of the detector from the mounting plate initiates a “tamper” transmission. The tamper
condition is restored after the detector is mounted on the plate.
Wireless Transmissions
A supervisory message is transmitted to the control panel at 64-minute intervals for the WS4936
and 12-minute intervals for the WS4936EU/WS8936 models. If the signal is not received the control
panel determines that the detector is missing. The detector transmitsthe following:
lAlarm /Alarm Restore - (heat or smoke alarm). Transmitted at time of occurrence.
lTamper / Tamper Restore - (tamper switch activated) 10 second maximum delay on restore
before transmission.
lLow Battery - (battery voltage falls below threshold). Battery voltage is tested & transmitted at
the time of a supervisory or other transmissions.
lTrouble - (detector fault or sensor compensation limit reached). Troubles are transmitted at the
time of occurrence (one trouble per supervisory interval).
Batteries
NOTE: The batteries must be replaced by service persons only.
The wireless smoke heat alarm is powered by 3 AAA Duracell Procell PC2400 or 3 AAA Energizer
E92 batteries (included). The detector regularly checks for a low battery. If a low battery is detected,
the transmitter sends a low battery message to the control panel, which displays the detector's ID at
low battery. In addition, the yellow LED of the detector will blink every 12 seconds. The detector's
sounder will chirp every 48 seconds (yellow LEDcontinues to blink) until the batteries are replaced.
Pressing the hush button will silence the chirps for 12 hours,if no other trouble conditions exist. The
batteries should be replaced when the chirps begin. Replace the batteries with new ones.
Battery Installation and Replacement
To replace batteries:
1. Remove the detector from its mounting base by twisting the detector counterclockwise. Care-
fully remove batteries bylifting from the “+” end using a flathead screwdriver and dispose of
them according to local regulations.
2. To ensure a proper power-down sequence, wait a minimum of 20 seconds before installing
new batteries.
3. Install 3 new AAA batteries (available from a local Duracell or Energizer dealer) in the battery
compartment.Install the batteries by inserting the “-” end first, then pushing the “+” end down.
If the batteries are incorrectly inserted, please remove them carefully by lifting them out from

the “+” end and correctly re-inserting them.
BATTERY COMPARTMENT

4. Re-install the detector on its mounting base by turning the detector clockwise until the mating
marks align.
5. After the power-up sequence, the green LED should blink once every 12 seconds to indicate
normal operation. If the batteries are not installed correctly, the detector will not operate and
the batteries may be damaged. Ifthe detector does not power up, check that the batteries are
installed correctly and fully charged.
6. Test the detector (as described later).
CONSTANT EXPOSURES TO HIGH OR LOW TEMPERATURES OR HIGH HUMIDITY MAY
REDUCE BATTERY LIFE.
Installation Instructions
The WS4936 / WS4936EU / WS8936 Series wireless smoke detector shall be installed and used
within an environment that provides the pollution degree max 2 and overvoltages category II in non-
hazardous locations, indoor only. The equipment is designed to be installed by SERVICE
PERSONS only; (SERVICE PERSON is defined as a person having the appropriate technical train-
ing and experience necessary to be aware of hazards to which that person maybe exposed in per-
forming a task and of measures to minimize the risks to that person or other persons).
1. Smoke Detector Placement
Research has shown that all hostile fires in homes generate smoke to a greater or lesser extent.
Experiments with typical fires in homes indicate that detectable quantities of smoke precede detect-
able levels of heat in most cases. For these reasons, smoke alarms should be installed outside of
each sleeping area and on each storey ofthe home.
The following information is for general guidance only and it is recommended that local fire codes
and regulations be consulted when locating and installing smoke alarms. It is recommended that
additional smoke alarms beyond those required for minimum protection be installed. Additional
areas that should be protected include: the basement; bedrooms, especially where smokers sleep;
dining rooms; furnace and utility rooms; and any hallways not protected by the required units. On
smooth ceilings, detectors may be spaced 9.1m (30 feet) apart as a guide. Other spacing may be
required depending on ceiling height, air movement, the presence of joists, uninsulated ceilings,
etc. Consult National Fire Alarm Code NFPA 72, CAN/ULC-S553-02 or other appropriate national
standards for installation recommendations.
lDo not locate smoke detectors at the top of peaked or gabled ceilings; the dead air space in
these locations may prevent the unit from detecting smoke.
lAvoid areas with turbulent air flow, such as near doors, fans or windows. Rapid air movement
around the detector may prevent smoke from entering the unit.
lDo not locate detectors in areas of high humidity.
lDo not locate detectors in areas where the temperature rises above 38ºC (100ºF) or falls below
5ºC (41ºF).
lSmoke detectors must always be installed in USA in accordance with Chapter 29 of NFPA 72,
the National Fire Alarm Code: 29.5.1.1.
Where required by applicable laws, codes, or standards for a specific type of occupancy, approved
single- and multiple-station smoke alarms shall be installed as follows:
1. In all sleeping rooms and guest rooms.
2. Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft) of any door to a
sleeping room, the distance measured along a path of travel.
3. On every level of a dwelling unit, including basements.
4. On every level of a residential board and care occupancy (small facility), including basements
and excluding crawl spaces and unfinished attics.
5. In the living area(s) of a guest suite.
6. In the living area(s) of a residential board and care occupancy (small facility).
NOTE: In Australia the device shall not be installed in locations where the normal ambient
temperature is lower than 5ºC or higher than 45ºC.

2. Mount Smoke Detector Backplate
NOTE: These alarm devices should only be installed by a competent engineer / technician.
This device should not be used with a guard.
Once a suitable location is found, mount the detector backplate.Install the mounting base on the ceil-
ing or on the wall (if local ordinancespermit) using screw locations as required. Use the two screws
and anchors provided. Maneuver the base so the screws are at the elbow of the screw slots and
secure.
100 mm (4 in.) minimum
100 mm (4 in.)
minimum
3. Mounting
Fit the detector inside the base by aligning it over the base (detector's alignment notch should be
slightly offset from the mounting base tamper release tab) then turn the detector clockwise until it
clicks in place.
4. Test Unit
NOTE: The central monitoring station (if used) should be notified prior to the test being generated.
This will prevent a false alarm and an unnecessary response from the central monitoring
station.
Initiate test by pressing the test button for 5 seconds minimum. Alarm activation is indicated by the
flashing LED, the sounder, and transmission of the alarm signal to the control panel. The detector
restores to normal when the test button is released.
NOTE: Allow a minimum of 20 seconds after power up and , after test, alarm or tamper restore activ-
ations. Do not use test button when smoke is present.
NOTE: If the detector is in one of the following states when a test is initiated; it will not enter an alarm
state.
lTamper, (detector not installed on mounting plate)
lCompensation Trouble
lOther internal faults that could prevent a smoke or heat alarm

5. Device Enrollment
The 6-digit serial number located on the back of the smoke detector housing must be enrolled into
the alarm control panel with Installer programming. Refer to the receiver Installation Manual for
details. For placement tests remove detector from backplate for one second (tamper) then reattach.
Wait at least 30 seconds for test result before activating again.
Owner's Instructions
Fire Safety In The Home
Most fires occur in the home, and to minimize this danger, it is recommended that a household fire
safety audit be conducted and a family escape plan be developed.
Household Fire Safety Audit
1. Are all electrical appliances and outlets in safe condition? Check for frayed cords, overloaded
lighting circuits, etc. If you are uncertain about the condition of your electrical appliances or
household service, have a professional evaluation.
2. Are all flammable liquids safely stored in closed containers, and in a cool and well ventilated
area? Cleaning the unit with flammable liquids should be avoided.
3. Are hazardous materials (i.e., matches) out of the reach of children?
4. Are furnaces and wood burning appliances properly installed, clean, and in good working
order? If in doubt, have a professional evaluation.
Family Escape Planning
There is often very little time between the detection of a fire and the time it becomes deadly.
Because of this, it is very important that a family escape plan be developed and rehearsed.
lEvery family member should participate in the escape plan.
lStudy the possible escape routesfrom each location within the house. Since many fires occur at
night, special attention should be given to the escape routes from sleeping quarters.
lIt is essential that escape from a bedroom be possible without opening the interior door. Con-
sider the following when making your escape plans:
lEnsure that doors and windows that open to the outside are easily opened. Ensure that they
are not painted shut and that the locking mechanisms operate smoothly.
lIf opening or using the exit is too difficult for children, the elderly or handicapped, plans for their
rescue should be developed. This plan includes making sure that those who are to perform the
rescue can promptly hear the fire warning signal.
lIf the exit is above the ground level,an approved fire ladder or rope should be provided, as well
as training in its use.
lExits on the ground level should be kept clear. Be sure to remove snow from exterior patio
doors in the winter and that outdoor furniture or equipment does not block exits.
lThe family should have a predetermined assembly point where everyone can be accounted for;
for example, across the street or at a neighbor’s house.
lOnce everyone is out of the house, call the Fire Department.
lA good plan emphasizes a quick escape. Do not investigate first or attempt to fight the fire, and
do not attempt to rescue belongings or valuables as this takes up time. Once outside, do not re-
enter the house; wait for the Fire Department.
lWrite the plan down and rehearse it frequently so that should an emergency ever arise, every-
one will know what to do. Revise the plan as conditions change; for example, when there are
more or fewer family members in the home or if there are changes to the house.
lMake sure your fire warning system is operational by conducting weekly tests. If you are unsure
about system operation, contact your smoke detector installer or dealer.
lDSC recommends that you contactyour local Fire Department and request further information
on home fire safety and escape planning. If available, have your local fire prevention officer con-
duct an in-house fire safety inspection.
Testing Your Smoke Detector
Follow the test procedure described here or contact your smoke detector dealer or installer for
testing instructions. DSC recommends that you test the entire alarm system at least once a
week to verify the operation of all system functions.
Smoke Detector Unit Test
Initiate testby pressing the testbutton for 5 seconds (min.), the sounder makes clicking noises dur-
ing this time. Press the button until the unit alarm sounds, an alarm should be sent to the control
panel. When the button is released, the alarm should cease. If this does not occur, ensure batteries
are the correcttype, in good condition and are installed correctly.
Upon completing the functional testing of the smoke detector, check the unit’s sensing chamber to
ensure proper operation. To test the sensing chamber, wave a lit cotton wick or punk stick around
the outside of the unit until a generous amount of smoke enters the sensing chamber or the unit
alarms. If the smoke detector does not function properly, call your smoke detector installer or dealer
for service.
Owner’s Maintenance
The smoke detector is designed to require minimum maintenance. If the case becomes dusty,
vacuum with a small brush attachment. Ifthe case is greasy, wipe the case gently with a soft cloth
slightly dampened with soapy water.

Never disassemble the smoke detector; there are no user serviceable parts inside the unit.
You may only remove detector from backplate to replace batteries if not serviced by installer.
When replacing the batteries, follow the instructions specified within the Installation Instruc-
tions.
Never paint the unit. Paint may prevent smoke from enteringthe unit. If you are planning renov-
ations or repainting, contact your installer and ask that the unit be temporarily removed until
work is complete.
If the unit is located in an area where it is exposed to high levels of dust or insects and causes false
alarms, it may require service; contact your smoke detector installer or dealer.
Testing and maintenance procedures shall be in accordance with CAN/ULC-S552-02.

Introduction
Le détecteur WS4936 / WS4936EU / WS8936 est un détecteur de fumée photoélectrique sans fil
disposant d’une consigne de température fixe, d’une fonction de détection d’élévation de la tem-
pérature et d’une alarme par capteur piézoélectrique interne. Trois versions sont disponibles: une
version à 433MHz pour l’Amérique du nord (WS4936), une version européenne/internationale et
australienne à 433MHz(WS4936EU) et une version européenne à 868MHz (WS8936).
REMARQUE: Le détecteur de chaleur basé sur l’élévation de la température n’a pas été examiné
par cULus.
REMARQUE: Les versions AUS et EU ne disposent pas d’une détection de chaleur à température
fixe, mais DISPOSENT d’une détection à élévation de température.
Dispositifs compatibles
Ce détecteur de fumée est compatible avec les centrales DSC homologuées UL/ULC et les récep-
teurs sans fil DSC suivants: SCW9045-433, SCW9047-433, SCW9055(D)(G)(I)-433, SCW9057 (D
(G)(I)-433, RF5132-433, RF5108-433, RFK5500-433, RFK5501-433, RFK5508-433, RFK5516-
433, TR4164-433, WS4920, RF4164-433, SCW9067(H)(C)-433.
Fonctionnement
L’appareil effectue une détection de fumée ou d’élévation de la chaleur toutes les 7 à 8secondes.
Au cours de cette opération, l’appareil effectue aussi un autodiagnostic et contrôle la présence de
pannes et de sabotage. Lors d’un fonctionnement normal, le voyant vert clignote toutes les
12secondes et l’avertisseur reste silencieux.
Alarme de détection de fumée
Le détecteur de fumée déclenchera une alarme lorsque le niveau de signal dépasse le seuil
«d’alarme» et se rétablira automatiquement lorsque le niveau de signal tombe en-dessous du
seuil de «rétablissement» d’alarme. Lors de l’alarme, le voyant clignotera 1fois par seconde et
l’avertisseur émettra la séquence temporelle d’évacuation.
Mise sous silence de l’alarme
Ce détecteur de fumée est doté d’une fonction de mise sous silence de l’alarme qui se réinitialise
de façon automatique. Quand le détecteur est en alarme, une pression sur le bouton Test/Si-
lence/Réinitialisation mettra sous silence l’annonce locale de l’alarme et transmettra un événement
de rétablissement d’alarme à la centrale. Le voyant lumineux clignotera toutes les 8 secondes (pen-
dant 10 minutes max.) pour indiquer que l’alarme est mise sous silence. Le clignotement du voyant
s’arrête quand l’unité retourne en fonctionnement normal. La fonction de mise sous silence de
l’alarme a une durée fixe qui désensibilise le détecteur de fumée pendant 8 minutes.
La mise sous silence de l’alarme ne désactive pas le détecteur mais réduit plutôt sa sensibilité de
détection. À la suite de la mise sous silence, le détecteur de fumée revient automatiquement au fonc-
tionnement prévu.Si la fumée autour du détecteur estsuffisamment dense pour supposer une situa-
tion de danger potentiel, il reste en alarme, ou éventuellement revient rapidement à l’étatd’alarme.
Panne du détecteur
Lorsque le détecteur rencontre une panne générale, le voyant jaune clignote une fois toutes les
quatre secondes et l’avertisseur émettra une compression d’impulsions (gazouillement) toutes les
48secondes. Après 12heures, la centrale affichera une perte de message de supervision.

Fonction de souillure du détecteur
Lorsque le détecteur est souillé, le voyant jaune clignote une fois toutes les 8secondes et l’aver-
tisseur émettra une compression d’impulsions toutes les 48secondes. Consultez le paragraphe sur
la MAINTENANCE pour nettoyer le détecteur. Après 12heures, la centrale affichera une perte de
message de supervision.
Alarme de détection de chaleur
Le détecteur de chaleur (versions cULus uniquement) sera en alarme lorsque le niveau de signal
de détection de chaleur dépasse le seul d’alarme de détection de chaleur (135°F/57°C) et se réta-
blira automatiquement lorsque le niveau de signal de détection de chaleur tombe en-dessous du
seuil d’alarme de détection de chaleur (rétablissement). Le détecteur passera aussi en alarme si
une rapide élévation de la température est détectée sur une courte période. Lors de l’alarme, le
voyant clignotera 1fois par seconde et l’avertisseur émettra la séquence temporelle d’évacuation.
Contact anti-sabotage
Le retrait du détecteur de la plaque de montage démarre une transmission de «sabotage». L’état
de sabotage estrestauré une fois le détecteur remonté sur la plaque.
Transmissions sans fil
Un message de supervision est transmis vers la centrale à intervalles de 64minutes pour le
WS4936 et à intervalles de 12minutes pour les modèles WS4936EU/WS8936. Si le signal n’est
pas reçu, la centrale considèrera le détecteur manquant. Le détecteur transmet les événements
suivants:
lAlarme/fin d’alarme - (alarme de détection de chaleur ou de fumée). Envoyé à chaque fois
qu’ils se produisent.
lSabotage/fin de sabotage - (contactanti-sabotage activé) délai de 10secondes au maximum
au rétablissement avant transmission.
lBatterie faible - (la tension de batterie estinférieure au seuil). La tension de la batterie esttes-
tée et transmise au moment des transmissions de supervision ou autres.
lProblème - (panne du détecteur ou limite de compensation du détecteur atteinte). Les pro-
blèmes sont transmis au moment qu’ils se produisent (un problème par intervalle de super-
vision).
Batteries
REMARQUE: Les batteries doivent être remplacées uniquement par des personnes qualifiées.
Le détecteur de chaleur et de fumée sans fil estalimenté par 3piles AAA Duracell Procell PC2400
ou AAA Energizer E92 (fournies). Le détecteur contrôle régulièrement si la tension des batteries
est faible. Si un problème de batterie est détecté, un message de batterie faible est envoyé à la cen-
trale qui affichera l’identifiant du détecteur avec une batterie faible. En plus, le voyant jaune du
détecteur se mettra à clignoter toutes les 12secondes. L’avertisseur du détecteur émettra une com-
pression d’impulsions toutes les 48secondes (le voyant jaune continuera de clignoter) tant que les
batteries ne sont pas remplacées. Un appui sur le bouton de mise sous silence suspendra l’émis-
sion de la compression d’impulsions pendant 12heures, si aucun autre problème n’existe. Les
