Table 1: Detector and Status Indication
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 transmits the following:
Alarm / Alarm Restore - (heat or smoke alarm). Transmitted at time of occurrence.
l
Tamper / Tamper Restore - (tamper switch activated) 10 second maximum delay on restore
l
before transmission.
Low Battery - (battery voltage falls below threshold). Battery voltage is tested & transmitted at
l
the time of supervisory or other transmissions.
Trouble - (detector fault or sensor compensation limit reached). Troubles are transmitted at the
l
time of occurrence.
Batteries
NOTE: The batteries must be replaced by service persons only.
The wireless smoke and heat alarm is powered by 3 AAA batteries. Use Duracell Procell PC2400
or Energizer E92 for the WS4936. Use Duracell Procell MN2400 for the WS4936EU/WS8936.
Expected battery life is 3 years under typical use. 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 dis-
plays 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 bat-
teries 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 by lifting 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, remove them carefully by lifting them out from the "+"
