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 (UL/ULC 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 sig-
nal 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. Dur-
ing an alarm the LED will flash 1/second and the sounder will
sound the evacuation temporal pattern (UL, EU) or con-
tinuous beeps (ULC).

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.
a “tamper” transmission. The tamper condition is restored
after the detector is mounted on the plate.
Wireless Transmissions
A supervisory message is transmitted at 64 minute intervals
(12 minutes in EU model) to the control panel. If the signal is
not received the control panel determines that the detector is
missing.
The detector transmits the following:

Batteries
NOTE: The batteries must be replaced by service persons
only.
The wireless smoke heat alarm is powered by 3 AAA Dur-
acell 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 bat-
teries 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. Be
sure to replace the batteries with fresh ones.

Battery Installation and Replacement
To replace batteries:
1. Remove the detector from its mounting base by twisting
the detector counterclockwise. Remove and dispose of
the batteries according to local regulations.
the batteries according to local regulations.
2. To ensure a proper power-down sequence, wait a min-
imum of 20 seconds before installing new batteries.
3. Install 3 new AAA batteries (available from a local Dur-
acell or Energizer dealer) in the battery compartment. If
the batteries are incorrectly inserted, please remove
them carefully with a non-conductive tool and correctly
re-insert them.

re-insert 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 oper-
ation. If the batteries are not installed correctly, the
detector will not operate and the batteries may be dam-
aged. If the detector does not power up, check that the
batteries are installed correctly and fully charged.

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 training and experience
necessary to be aware of hazards to which that person may
be exposed in performing a task and of measures to minimize
the risks to that person or other persons.)

1. Smoke Detector Placement
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, unin-
sulated ceilings, etc. Consult National Fire Alarm Code NFPA
72 Chapter 11, CAN/ULC- S553- 02 or other appropriate
national standards for installation recommendations.

l
Do 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. Avoid areas
with turbulent air flow, such as near doors, fans or win-
dows. Rapid air movement around the detector may pre-
vent smoke from entering the unit.
