Introduction
The SA-61 is a battery-operated Wireless Smoke Detector.
433.92 MHz or 868.35 MHz.
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.

smoke. In Alarm mode, the indicated LED and the RF
LED quickly flashes and the Piezoelectric sounder is
activated.

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.
