Introduction
A conventional smoke detector is a safety device designed to sense
the presence of smoke in the air and trigger an audible alarm to
alert occupants of a potential fire. It typically consists of the
following key components:
Sensing Chamber:
The sensing chamber is where the smoke detection mechanism is
housed.
It contains either photoelectric sensor, which is the core
technology used to detect smoke.
Alarm Horn/Sounder:
When smoke is detected, the smoke detector activates a loud audible
alarm, typically a high-decibel beeping or buzzing sound.
The alarm is intended to wake up and alert occupants to the
presence of smoke, prompting them to evacuate the area.
Power Source:
Conventional smoke detectors can be powered by a hardwired
connection to the building's electrical system.
Status Indicators:
Smoke detectors often have visual status indicators, such as LED
lights, to provide feedback on the device's operational status.
These indicators can signal issues like low battery, sensor
malfunctions, or normal operation.
Mounting:
Conventional smoke detectors are typically mounted on the ceiling
or high on walls, as smoke typically rises and accumulates at the
ceiling level.
The mounting hardware allows for easy installation and replacement
of the detector as needed.

Installation
INSTALLATION
NOTE: All wiring must conform to applicable local codes, ordinances, and regulations.
NOTE: Verify that all detector bases are installed, that the initiating-device circuits have been tested, and that the wiring is correct.
Remove power from initiating-device circuits before installing detectors.
1. Wire the sensor base per the wiring diagram, Figure 1.
2. Install the sensor into the sensor base. Push the sensor into the
base while turning it clockwise to secure it in place.
3. After all sensors have been installed, apply power to the control
unit.
4. Test the sensor(s) as described in the TESTING section of this
manual.
5. Notify the proper authorities that the system is in operation.
Warning:Forbid connect 24VDC directly without current-limiting resistance.
Otherwise, the detector would be burnt out.
