SA-61

Wireless Smoke Detector

Installation Manual

1. Introduction

The SA-61 is a battery-operated Wireless Smoke Detector.

It is available in two frequencies:

The smoke sensor unit can easily be plugged into or detached from the
wireless base unit (AS-60) for cleaning and maintenance purposes.

A mechanical key on the sensor is designed to avoid mismatching or
incorrect installation of the sensor and base. The sensor chamber is
engineered to sense smoke from a wide range of combustion sources.
The chamber is well protected from insects and dust contamination.

A LED indicator on the sensor unit shows the operating status and
Alarm mode, while an RF LED is located in the base unit and indicates
RF transmissions, such as alarms and tamper.

The SA-61 smoke detector has a low profile, as well as a professional
and trendy appearance.

Report Types

The indicated LED flashes once every 344 seconds
(to save battery life) to show it is working.

The detector goes into Alarm mode if it detects
smoke. In Alarm mode, the indicated LED and the RF
LED quickly flashes and the Piezoelectric sounder is
activated.

When the battery voltage is low, the detector beeps
every 43 seconds.

When the sensor is disconnected from the base or
the base unit from the ceiling.

Alarm Report:

• Every 20 seconds during first 3 min

• Every 3 min from 3 min till 30 min

• Alarm event is no longer sent after 30 min or

immediately upon Alarm Restore (When the am-

bient environment somke concetration is lower than

the alarm level for a zone)

3. Installation

3.1 Choosing a Mounting Location

A smoke detector should be installed according to NFPA (National Fire
Protection Association) Standard 72. For complete coverage in
residential units, smoke detectors should be installed in all rooms, halls,
storage areas, and basements. At the least, one detector should be
placed on each floor and in each sleeping area.

Install smoke detectors as close to the center of the ceiling as possible
or at least 10 cm (4 inches) away from any wall or corner.

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 and affected the accuracy.

3.2 Smoke Detector Limitations

 Smoke detectors will not sense a fire if the smoke does not reach

the sensor.

 Smoke detectors may not be heard. Be sure to locate the smoke

detector within hearing distance.

 Smoke from a slow fire rises slowly and may not reach the smoke

detector until the fire gets bigger.

 To keep your smoke detectors working properly, be sure to

maintain the unit according to manufacturer’s recommendations
and UL and NFPA standards.

3.3 Disassembly

The unit arrives assembled, so you must disassemble the unit into its
three pieces before you can mount it.

To disassemble:

1. Turn the sensor counter-clockwise to the “Loose” position as
shown in Figure 2 and gently remove the sensor.

Figure 2: Loose and Lock Positions

2. Gently separate the top part of the base unit from the lower part.

3.4 Mounting the Base Unit

The AS-60 base unit provides different punch out options for different
gang box standards for mounting to 3 1/2-inch and 4-inch octagonal,
single-gang, and 4-inch square back boxes (Figure 3).

3.5 Inserting the Battery

The battery compartment is designed to meet UL requirement. A lever
has been inserted to avoid attaching the sensor unit without the
battery being inserted.

To insert the battery:

1. Load the battery into the base compartment as shown in Figure 4.

Figure 4: Battery Installation

3.6 Assembly

Once you have mounted the base unit and inserted the battery, you
are ready to close the unit.

To assemble the unit:

1. Replace the top part of the base unit with its bottom part that has
been mounted by lining up the two lines as shown in Figure 5.

Figure 5: Base Cover Insertion

Figure 3: Punch Out Options for Various Gang Box Standards

To mount the base unit:

1. Mark two mounting points in the wall.

2. Drill into the marked points and insert wall plugs/gang box.

3. Screw and fix the base unit.

2. Attach the sensor unit onto the base unit as shown in Figure 6 and
turn the sensor clockwise to the Lock position (Figure 2).
