INSTALLATION PREPARATION

WeR@Home+™ Smoke Alarm User Guide

2. Installation Preparation

It is important to determine in which rooms and where in each room to install the SKs so that their

positioning is most effective.

2.1. Required Equipment

Caution: Do not use the SK with smoke detector guards unless the usage has

been evaluated and found suitable for the SK.

Before beginning, prepare the following equipment:

 A drill with a standard 5 mm (3/16 in.) bit

 A standard Phillips screwdriver

 Two DIN 7982 cross recessed countersunk head tapping screws (3.5 x 16 mm (.14 x .63 in.)) and

wall anchors - provided

 Two 1.5V AA alkaline batteries - not provided.

Refer to Appendix A Certification Notes on page 28.

2.2. Location Recommendations

As a fire prevention device, there are standard locations and conditions for installing the SK.

2.2.1 Acceptable Structures for SK Usage

The SK is designed for residential units only. The SK can be used in a single family home or in an

apartment building. In multi-family buildings, each residence should install its own SKs. The SKs should

be installed in the appropriate rooms, according to section 2.2.2.

SKs installed in common areas, such as on porches or in outside hallways, may not provide sufficient

early warnings for residents.

INSTALLATION PREPARATION

WeR@Home+™ Smoke Alarm User Guide

WARNING! Do not use this alarm in non-residential buildings. Warehouses,

industrial buildings, commercial buildings, and other non-residential buildings

require special fire detection and alarm systems. See NFPA 101 (Life Safety Code),

NFPA71, 72A, 72B, 72C, 72D, and 72E for fire alarm requirements in buildings not

defined as “households”.

The SK is not a substitute for a complete fire detection system for places where many people live or

work, such as hotels, motels, dormitories, hospitals, nursing homes, and group homes of any kind,

even if they once were single family homes.

2.2.2 Acceptable Installation Locations

For complete coverage in residential units, SKs should be installed in all rooms in each family residence

including:

 Halls and passageways

 Storage areas

 Basements

 Attics

Minimum coverage is one SK on each floor and one in each sleeping area.

For optimal detection, consider the following recommendations when selecting an installation

location for the SK:

 Install the SK on the ceiling.

 Install the SK in the hallway outside every separate bedroom area, as shown in Figure 2.

 Install two SKs in homes with two bedroom areas, as shown in Figure 3.

INSTALLATION PREPARATION

WeR@Home+™ Smoke Alarm User Guide

Figure 2 shows an example of locations for installing SKs in a single residence with one bedroom.

Figure 2 – Single Sleep Area in a Single-floor Residence

Figure 3 shows an example of locations for installing SKs in a single-floor residence with more than one

bedroom.

Figure 3 – Multiple Sleep Areas in a Single-floor Residence

 Install an SK on every floor of a multi-floor residence, as shown in Figure 4 below.

Figure 4 – Multi-floor Residence

INSTALLATION PREPARATION

WeR@Home+™ Smoke Alarm User Guide

WARNING! Be sure doors or other obstructions do not block the path of smoke

to the alarm.

 Install a minimum of two SKs in any household.

 Install the SK inside every bedroom.

 Install an SK at both ends of a hallway, if the hallway is more than 12 m (40 ft.) long.

 Install an SK inside every room where one sleeps with the door partly or completely closed.

The smoke could be blocked by the door. An SK installed in a hallway may not wake up the

sleeper if the door is closed.

 Install the SK in the basement at the bottom of the basement stairwell.

 For a two floor residence, install the SK at the top of the first-to-second floor stairwell.

 Install additional SKs in the residence in the following areas:

 Living room

 Dining room

 Family room

 Attic

 Utility

 Storage rooms

 Install the SK as close to the center of the ceiling as possible. If this is not practical, install the

SK on the ceiling no closer than 10 cm (4 in.) from any wall or corner.

 If ceiling mounting is not possible and wall mounting is permitted by the local and state codes,

mount the SK on a wall 10 ~ 15 cm (4 to 6 in.) from the ceiling.

 In rooms with sloped, peaked, or gabled ceilings, mount the SK 0.9 m (3 ft.) measured

horizontally from the highest point of the ceiling.

Essence recommends using additional smoke alarms to obtain increased protection for areas

separated by a door from the areas protected by the smoke alarms required under the NFPA Standard

72, Section 2-4.1.1.

The recommended additional areas are:

 Living room

 Dining room

 Bedroom

 Kitchen

INSTALLATION PREPARATION

WeR@Home+™ Smoke Alarm User Guide

 Attic (finished or unfinished)

 Furnace rooms

 Utility room

 Basement (finished or unfinished)

 Garage (integral or attached)

 Hallways

2.2.3 Unacceptable Installation Locations

False alarms occur if SKs are installed where they do not work properly. To avoid false alarms, do not

install an SK in the following locations:

 Areas where combustion particles are present, such as:

 Kitchens with few windows or poor ventilation

 Garages where there may be vehicle exhaust

 Near furnaces

 Near hot water heaters

 Near space heaters

 Less than 6 m (20 ft.) from places where combustion particles are normally present, like

kitchens.

If a 6 m (20 ft.) distance is not possible, as in a mobile home, install the SK as far away from the

combustion particles as possible, preferably on the ceiling.

To prevent false alarms, provide good ventilation in such places.

Combustion particles are the by-products of something that is burning. An SK can sense combustion

particles in normal air-flow paths. An SK should avoid air streams that have combustion particles. They

should be located where air streams pass by kitchens.

 Damp/humid areas or near bathrooms with showers:

Moisture in the air can enter the detection chamber. Upon cooling, water droplets can cause

false alarms.

Install SKs at least 3 m (10 ft.) from bathrooms.

 Very cold or very hot areas, including unheated buildings and outdoor rooms:

If the temperature goes above or below the operating range of the SK, the SK will not work

properly. Refer to 7 Specifications on page 26.

 Very dusty or dirty areas:

INSTALLATION PREPARATION

WeR@Home+™ Smoke Alarm User Guide

Dirt and dust can build up in the alarm’s detection chamber, making it overly sensitive. In

addition, dust or dirt can block openings to the detection chamber and keep the alarm from

sensing smoke.

 Drafty areas and areas near fresh air vents, air conditioners, heaters or fans:

Fresh air vents and drafts can drive smoke away from SKs.

 Dead air spaces near the top of a peaked roof or in the corners formed by ceilings and walls:

Dead air can prevent smoke from reaching an alarm.

 In insect-infested areas:

If insects enter an alarm’s detection chamber, they may cause a false alarm.

Where bugs are a problem, get rid of them before installing an alarm.

 Near fluorescent lights:

Electrical discharges from fluorescent lights can cause false alarms.

Install SKs at least 1.5 m (5 ft.) from fluorescent lights.

WARNING! To prevent injury, the SK must be securely attached to the ceiling (or

wall) in accordance with the installation instructions.

OPERATION

WeR@Home+™ Smoke Alarm User Guide

4. Operation

The SK senses the smoke that enters the smoke detection chamber. The SK does not detect gas, heat,

or flames. When properly positioned, installed, and maintained, the SK is designed to give early

warnings of fire by sounding an alarm. Sounding the alarm allows time for the residents to escape

before the fire spreads.

When the SK detects smoke:

 An alarm is sounded.

 The alarm LED lights up Red.

 A notification is sent to the CP.

If the alarm sounds and you are not testing the SK, the SK may have detected smoke. Proceed as

follows:

1. Determine if:

 The alarm is real

 There is smoke

 A possible fire

 The alarm is false.

2. If the alarm is triggered by a real threat of fire, evacuate as rehearsed and call the fire department.

3. If the alarm is triggered by smoke from a non-serious event such as smoke from cooking, open a

window and fan the air to remove the smoke or dust. The alarm turns off as soon as the air is

completely clear of smoke.
