WS4936/WS4936EU(433MHz)/WS8936(868MHz) Series Wireless Smoke Detector
Installation and Operating Instructions
Read this instruction sheet thoroughly before installation and use of the WS4936/WS4936EU/WS8936
Introduction
The WS4936/WS4936EU/WS8936 is a wireless photoelectric smoke detector with a fixed tem-
perature threshold, a rate of rise heat detector and an internal piezoelectric alarm. Three versions
are available: a 433MHz North American version (WS4936), 433MHz European/International and
Australian 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
Compatible Devices
This smoke detector is compatible with the following UL/ULC Listed DSC Wireless Control Panels
and Wireless Receivers: 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 .
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.
NOTE: The sounder and LED are not synchronised.
