WS4916 Series Wireless Smoke Detector

Installation and Operating Instructions

Read this instruction sheet thoroughly before installation and use of the WS4916 Wireless Smoke Detector

Introduction

The WS4916 is a wireless photoelectric smoke detector with a
fixed temperature heat detector and an internal piezoelectric
alarm. Three version are available: US version (UL), Canadian ver­sion (ULC) and an International version (EU).

Alignment Marks

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 LED will flash every 50 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 automatically 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 (UL, EU) or continuous beeps (ULC).

The smoke detector has a preset warning threshold at 75% of the
alarm threshold. If the signal level stays above this threshold, but
below the alarm threshold, for more than 120 seconds, the detec­tor will go into the 'warning' state. If the signal level falls below
the early warning 'restore' threshold, the detector will restore to
its normal state automatically. If the signal level rises above the
alarm threshold, the detector will go into alarm. The LED will flash
and the sounder will chirp every 50 seconds when in the warning
state.

NOTE: This feature is intended to provide a warning if the envi­ronment is persistently close to the alarm threshold and provide
more time to investigate and either escape or correct the situa­tion.

Smoke - Drift Compensation

The detector automatically compensates for long-term environ­mentally induced changes to maintain a constant smoke sensitiv­ity. When the drift compensation has reached its high or low limit
of adjustment, the detector will go into the trouble state.

Heat Alarm

The heat detector 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). During an alarm the LED will flash 1/second
and the sounder will sound the evacuation temporal pattern (UL,
EU) or continuous beeps (ULC).

Tam pe r

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 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:

• Alarm / Alarm Restore - (heat or smoke alarm). Transmitted at
time of occurrence.

• Tamper / Tamper Restore - (tamper switch activated) 10 second
maximum delay on restore before transmission.

• Low Battery - (battery voltage falls below threshold). The batteries
are tested & transmitted at the time of a supervisory or other trans­missions.

• Trouble - (detector fault or sensor compensation limit reached).
Troubles are transmitted at the time of occurrence (one trouble
per supervisory interval).

Batteries

The WS4916 is powered by two, 3VDC lithium batteries.

Do NOT use batteries other than those listed.

The low battery threshold is set so the batteries will provide not
less than 14 days of operation and at that point the detector will
send a 'low battery' signal. If the battery is still low 7 days after
falling through the low battery threshold, the horn will 'chirp'
once every 48 seconds until battery failure. During the first 7 days
after low battery detection, (non-chirp period), if the detector is
tested or goes into alarm, the horn will 'chirp' once the test or
alarm is restored and remain 'chirping' until battery failure.

Installation Instructions
Installation

The WS4916 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, uninsulated ceilings,
etc. Consult National Fire Alarm Code NFPA 72 Chapter 11, CAN/
ULC-S553-02 or other appropriate national standards for installa­tion recommendations.

•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 windows. Rapid air movement around
the detector may prevent smoke from entering the unit.

•Do NOT locate detectors in areas of high humidity.

•Do NOT locate detectors in areas where the temperature rises
above 38ºC (100ºF) or falls below 5ºC (41ºF).

Install Smoke detectors in
accordance with NFPA 72,
Chapter 11.

“Smoke detectors shall be
installed outside of each
sleeping area in the
immediate vicinity of the
bedrooms and on each
additional story of the
family living unit, includ­ing basements and
excluding crawl spaces
and unfinished attics. In
new construction, a
smoke detector also shall
be installed in each sleep­ing room.”

2. Mount Smoke Detector Backplate

Secure backplate to the mounting surface using the screws pro­vided.

Mounting Holes

Installer Compensation Reset

Cleaning or replacement of the smoke sensor chamber changes
the background signal/noise of the detector; this requires the
drift compensation be reset. Compensation trouble is one of the
faults indicated when the LED indicator is OFF while the sounder
is chirping.

1. Remove batteries, then short the detector battery contacts for 5
seconds to power down unit.

2.Replace batteries to power up unit while pressing the test but-

ton.

3.The tamper switch must not be pressed.

4.The LED will flash when 5 seconds has elapsed. Release the test

button within 2 seconds of the LED flash.

5.The LED will flash every 2 seconds for 1 minute. During this

period, the detector must be mounted.

Allow an additional 2 minutes for the detector to make
background level checks.

6.Test the detector to verify normal operation.

CAUTION: The dust cover protects the unit when not in service.
Remove the dust cover before use.

5. 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 activations. 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.

• Tamper, (detector not installed on mounting plate)

• Compensation Trouble

• Other internal faults that could prevent a smoke or heat alarm.

NOTE: Smoke sensitivity of installed detectors can be measured
without removal or an alarm being generated using the FSD-100
Smoke Detector Test Meter.

To test the unit using the FSD-100, set the test meter up to read
devices as per the instructions supplied. Depress the test button
on the smoke detector for 1 second and release.

NOTE: If the test button is held for 5 seconds or longer, an alarm
will be generated.

Move the test meter over the center of the detector, wait until
you hear the test meter beep, remove the unit and the informa­tion can be immediately reviewed. Please see the instructions
supplied with the FSD-100 Smoke Detector Test Meter for more
information.

6. 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.

Owners 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 chil-

dren?

4.Are furnaces and wood burning appliances properly installed,

clean, and in good working order? If in doubt, have a profes­sional evaluation.
