The WS8920 is a wireless repeater designed to extend the range of DSC one-way wireless
transmitters and to improve signal quality between the transmitter and receiver. Use the
WS8920 to remedy transmission problems caused by excessive noise or other interference, or
by long distances between devices and receivers. The maximum recommended number of
WS8920’s per alarm system is 4.
Each enrolled WS8920 occupies a zone slot. The WS8920 does not increase the number of
supported wireless zones. This is determined by the control panel’s wireless receiver. Only zones
requiring repeat functionality need to be enrolled on the WS8920. Ensure these zones are enrolled on
both the WS8920 and the receiver/control panel.

Install the WS8920 in the following order.
NOTE: When enrolling and placement testing the WS8920 with the alarm panel, refer to the
compatible control panel installation instructions for the appropriate programming sections.
Step 1: Temporarily Mounting the WS8920
Select a suitable location for the WS8920. Use the following list as a guide:
• Locate device near a power outlet
• Location should be free from vibration and shock
• Mount on a flat, stable surface
• Ideal location is mid-way between the wireless transmitter and receiver. The minimum distance
between the WS8920 and the receiver should be no less than 1 meter (3.28 feet)
Do not permanently mount the WS8920 until it has been placement tested. Temporarily
mount the unit using tape or other non-permanent, non-marking method. If the selected
location fails the placement test, the device must be repositioned.

Step 3: WS8920 Repeater Placement Testing (Interference
Detection)
Repeater placement test ensures the WS8920 is located in an area with low noise and
interference and can successfully receive signals from one-way wireless devices.
To perform a Repeater placement test:
1. Press and hold Programming button for 1 second to enter Programming mode. The “Mode
Entered” tone sounds (1 long beep). Repeater placement test is continuously active until
Programming mode is exited, times out after 4 hours or cover is put back on unit.
2. If RF traffic level or noise floor level is too high, the yellow LED lights steadily. If this occurs,
reposition unit until yellow LED turns off.
3. To exit Enroll/Placement mode, press Programming button again for 1 second or place cover
back on WS8920. The “Mode Exited” (3 beeps) tone sounds.
Step 4: Enrolling the WS8920 with the Alarm Panel
The WS8920 has a six-digit electronic serial number (ESN) that must be input to the alarm
panel during enrollment.
To quick enroll the WS8920 (available on selected alarm panels):
1. Enter Wireless Enrollment mode on alarm panel (see panel installation instructions).
2. Tamper WS8920 to transmit ESN.
3. Confirm ESN on alarm panel. Panel prompts for zone number.
4. Select and accept zone number for WS8920 to complete enrollment.
To manually enroll WS8920, consult alarm panel installation manual.
NOTE: For PowerSeries, Alexor, and SCW9045/47, use the serial number beginning with “2.” The
serial number beginning with “A” is for future use.
NOTE: Non-alarm zone type 26 is recommended. With this zone type, loss of AC or a low battery
condition are not reported to the central station. The alarm panel does not show a trouble for the zone
but will indicate it as open. Select the Force Arm attribute for this zone. Program a zone label to
identify the WS8920. e.g.,“Rpter 1 Pwr Trbl.”
Step 5: Placement Testing the WS8920
For optimal performance between the WS8920 and the alarm panel, the RF signal between the
two units should be as free from interference as possible.
To test the RF link between the WS8920 and the alarm panel:
1. Place alarm panel into placement test (see panel installation instructions) and select zone
where WS8920 is enrolled.
2. Tamper the WS8920.
• If alarm panel receives a strong signal, panel siren squawks once and “Location is Good” is dis-
played on alarm keypad.
• If alarm panel receives a weak signal, panel siren squawks three times and “Location is Bad” is
displayed on alarm keypad.
3. If alarm system indicates a weak signal or no response, check panel programming or reposition
WS8920 and repeat test. WS8920 should only be placed in location where multiple good results
are received.

Step 6: Quick Enroll/Placement Testing Devices
Up to 164 1-way wireless devices can be enrolled on the WS8920. During the first 4 hours of power
up, the WS8920 can be placed into Enroll/Placement Test modes. After the 4 hour time-out, access
to these modes is denied and the unit must be powered up again to enter Enroll/Placement mode.
NOTE: DLS cannot be used to enroll wireless devices on the WS8920. All wireless devices being
enrolled on the WS8920 must also be enrolled on the receiver/control panel.
To both enroll and placement test a device at the same time:
1. Press and hold Programming button for 1 second. “Mode Entered” tone (1 long beep) sounds.
The WS8920 is now in Enroll/Programming mode.
2. Trip and restore zone to be enrolled 3 times:
• Door and window contact - open/close or tamper/restore
• PIR and other stationary devices - tamper/restore
• Panic pendant - 3 to 4 button presses
• Wireless key - 3 separate button presses
3. Red LED (X) flashes until zone is enrolled. Once WS8920 has received signal from zone, Green
LED ( ) lights for 1 second and sounder emits “Zone Enrolled” (low to high) tone.
NOTE:
• If another zone is tripped during the enroll sequence, the enroll process must be restarted by trip-
ping and restoring the appropriate zone 3 times.
• A WS8920 can not enroll another WS8920.
•Stationary (permanently mounted) devices should only be enrolled with one WS8920. The
only exception is in Residential Fire installations, where smoke and CO detectors that are
enrolled with a WS8920 must be enrolled with at least two WS8920’s.
• Fobs and panic pendants may be enrolled with multiple WS8920’s.
• If an enrollment is attempted after all 164 device slots have been filled, the WS8920 emits a 2-
second error tone and all three LEDs light for 20 seconds to indicate that no further devices may
be enrolled.
4. After zone is enrolled, trip again to perform placement test (to test the signal between the
wireless device and the WS8920). Green LED flashes if signal is received.
• If “Good Zone Placement” tone (1 beep) sounds, device location is satisfactory and unit may be
permanently mounted.
• If “Bad Zone Placement” tone (3 loud beeps) sounds, reposition device and trip zone again. Con-
tinue until “Good Zone Placement” (1 beep) tone sounds.
5. Repeat steps 2-4 to enroll and placement test other zones.
• To exit, press Programming button again for 1 second or place cover back on WS8920. “Mode
Exited” (3 beeps) tone sounds.
NOTE: If the WS8920 tone can not be heard while testing the device, set the alarm panel into
individual placement test mode using the WS8920 serial number. The WS8920 placement test
results are sounded through the alarm panel siren.
• Although good results may be obtained on the WS8920, bad results are still possible from the
alarm panel due to collisions.
• Subsequent violations from an enrolled zone while the WS8920 is in programming mode will
initiate a placement test.

7
Global Placement Testing Devices
Conduct placement testing with doors and windows both open and closed to ensure acceptable
placement. To placement test a 1-way wireless device after the initial Enroll/Placement test process:
1. Place the alarm panel into individual placement test mode for the WS8920 zone (see control
panel installation instructions).
2. Press and hold Programming button for 1 second. “Mode Entered” tone (1 long beep) sounds.
WS8920 is now in global placement test mode. Each zone enrolled on WS8920 gives placement
test result when tripped.
• If “Good Zone Placement” tone (1 beep) sounds, device location is satisfactory and unit may be
permanently mounted.
• If “Bad Zone Placement” (3 loud beeps) tone sounds, reposition device and trip zone again.
Continue until “Good Zone Placement” tone (1 beep) sounds.
3. To exit, press Programming button again for 1 second or place cover back on the WS8920.
“Mode Exited” (3 beeps) tone sounds.
Step 7: Mounting the WS8920
Permanently mount the WS8920 only after completing multiple successful placement tests.
To mount the WS8920:
1. Ensure AC wire is run through channel on back of WS8920.
2. Remove front cover and secure unit to wall through mounting holes using all 4 wall plugs and
screws provided.
3. Place cover back on WS8920.
4. Plug AC adaptor into unswitched AC outlet.
Restoring the WS8920 to Factory Defaults
To restore factory default settings:
1. Within 1 minute of power up, press and hold Programming button for 10 seconds. Sounder
beeps after first second to indicate WS8920 is in Installer mode. After 10 seconds, WS8920
emits double long tone and all LEDs light.
2. Release Programming button and immediately press and hold again for 10 seconds. After 10
seconds, WS8920 emits a 4-second tone and all three LEDs flash.
NOTE: The second button press must occur within 20 seconds of the first or the WS8920 will exit
Enroll/Placement mode.
3. WS8920 beeps three times and LEDs return to normal state, indicating Installer mode exit. If
Installer mode exits before reset is complete, due either to time-out or tamper, repeat procedure.

Le WS8920 est un répéteur sans fil conçu pour étendre la portée des émetteurs sans fil à
communication unilatérale de DSC et pour améliorer la qualité du signal entre l’émetteur et le
récepteur. Utilisez le WS8920 pour remédier à des problèmes de transmission provoqués par
un bruit excessif ou autre interférence ou par de grandes distances entre les dispositifs et les
récepteurs. Le nombre maximum recommandé de WS1920 par système d'alarme est 4.
REMARQUE: Chaque WS8920 enregistré occupe un emplacement de zone. Le WS8920 n'aug-
mente pas le nombre de zones sans fil prises en charge. C'est le récepteur sans fil du panneau de con-
trôle qui le détermine. Seules les zones exigeant la fonctionnalité répéteur doivent être enregistrées
sur le WS8920. Vérifiez que ces zones sont enregistrées à la fois sur le WS8920 et le récepteur/pan-
neau de contrôle.
Le WS8920 est compatible avec les dispositifs sans fil DSC suivants :
REMARQUE: WS8920 n'est pas compatible avec les dispositifs à communication
bilatérale.

Installez le WS8920 dans l’ordre suivant :
REMARQUE: Lorsque vous enregistrez et faites un test de portée du WS8920 avec le panneau
d'alarme, consultez les instructions d'installation du panneau de contrôle compatible pour les sec-
tions de paramétrage appropriées.
Étape 1 : Installation temporaire du WS8920
Choisissez un endroit approprié pour le WS8920. Utilisez la liste suivante pour vous guider:
• Placez le dispositif près d’une prise électrique
• L’emplacement ne doit pas subir de vibration ou de choc
• Installez sur une surface plane et stable
• L’emplacement idéal est au milieu entre l’émetteur sans fil et le récepteur. La distance minimale
entre le WS8920 et le récepteur doit être d'au moins 1 mètres (3.28 pieds).
N’installez pas le récepteur définitivement avant d’avoir fait le test de portée.
Installez temporairement le dispositif à l’aide de ruban adhésif ou autre méthode non
permanente qui ne laisse pas de traces. Si l’emplacement choisi ne passe pas le test de portée,
le dispositif doit être déplacé.
Étape 2 : Mise sous tension
Connectez la pile de secours d’abord, puis branchez au secteur :
Pour connecter la pile :
1. Ouvrez le couvercle avant précautionneusement en mettant la tête plate d'un petit tournevis
dans les trous prévus à cet effet (voir Figure 3).
2. Connectez le câble de batterie à la borne sur la carte de circuit imprimé.
Selon l’état de charge de la pile, un trouble pile faible pourrait être enregistré à la première
mise sous tension. Le trouble pourrait prendre plusieurs heures avant d’être résolu.
Pour connecter l’adaptateur c.a.
1. Faites passer le fil c.a. dans le canal au dos du WS8920 et passez-le dans le trou du boîtier.

2. Connectez les fils c.a. aux bornes de la carte de circuit imprimé (voir Figure 4).
3. Faites passer le fil dans les pattes de fixation pour qu’il reste bien à sa place.
4. Branchez l’adaptateur c.a. dans la prise de courant murale.
Étape 3 : Test de portée du répéteur WS8920 (Détection des
interférences)
Le test de portée du répéteur assure que le WS8920 est placé à un endroit où il y a peu de bruit
et d’interférence et où il peut recevoir sans problème les signaux des dispositifs sans fil à
communication unilatérale.
Pour effectuer un test de portée du répéteur :
1. Appuyez et maintenez la Bouton Programmation pendant une seconde pour entrer dans le
mode de programmation. La tonalité « Entrée dans le mode » (1 long bip) est émise Le test de
portée est continuellement actif jusqu’à ce que l’on sorte du mode de programmation, qui
expire 4 heures plus tard ou lorsque le couvercle est remis sur le dispositif.
2. Si le niveau de trafic RF ou le niveau du plancher de bruit est trop élevé, le voyant DEL jaune
s’allume en continu sur le WS8920. Si cela se produit, déplacez le dispositif jusqu’à ce que le
voyant jaune s’éteigne.
3. Pour sortir du mode Enregistrement/Test de Portée, appuyez à nouveau sur la Bouton
Programmation pendant une seconde ou replacez le couvercle sur le WS8920. La tonalité de
« Sortie du mode » est émise.

Étape 4 : Enregistrez le WS8920 sur le panneau d'alarme
Le WS8920 possède un numéro de série électronique (NSE) à six chiffres qui doit être entré
dans le panneau d’alarme durant l’enregistrement.
Pour un enregistrement rapide du WS8920 (offert sur certains panneaux d’alarme) :
1. Saisissez le mode d’enregistrement sans fil sur le panneau d’alarme (voir instructions pour
l’installation du panneau).
2. Sabotez WS8920 pour transmettre le NSE.
3. Confirmez le NSE sur le panneau d’alarme. Le panneau affiche un message-guide demandant le
numéro de zone.
4. Choisissez et acceptez le numéro de zone pour le WS8920 pour finir l'enregistrement.
Pour enregistrer manuellement le WS8920, consultez le manuel d’installation du panneau.
REMARQUE: Pour PowerSeries, Alexor, et SCW9045/47, utilisez le numéro de série commençant
par un « 2 ». Le numéro de série commençant par un « A » est destiné aux panneaux futurs.
REMARQUE: Le type de zone 26 non-alarme est recommandé. Avec ce type de zone, la panne de
courant ou la pile faible ne sont pas signalées à la station centrale. Le panneau d’alarme n’indique
pas un trouble pour la zone, mais indique qu’elle est ouverte. La caractéristique « Armement forcé »
doit être choisie pour cette zone Programmez une étiquette de zone pour identifier le WS8920. Par
ex., « Rpter 1 Pwr Trbl. »
Étape 5 : Test de portée du WS8920
Pour une performance optimale entre le WS8920 et le panneau d'alarme, le signal RF entre les
deux unités doit avoir aussi peu d'interférences que possibles.
Pour tester le lien RF entre le WS8920 et le panneau d’alarme :
1. Faites un test de portée pour le panneau d’alarme (voir les instructions d’installation du
panneau) et choisissez la zone dans laquelle le WS8920 est enregistré.
2. Sabotez le WS8920.
• Si le panneau d’alarme reçoit un signal fort, la sirène du panneau fait un bruit de sonnerie une
fois et « Emplacement bon » est affiché sur le clavier d’alarme.
• Si le panneau d’alarme reçoit un signal faible, la sirène du panneau émet trois bruits de sonnerie
et « Emplacement mauvais » est affiché sur le clavier d’alarme.
3. Si l'alarme indique un signal faible ou pas de réponse, vérifiez le paramétrage du panneau ou
repositionnez le WS8920 et refaites le test. Le WS8920 ne doit être placé qu’à un endroit où
plusieurs bons résultats sont reçus.
