Smoke pellet test
This test is typically used for Class C installations.
Performing a smoke pellet test
1. Place a 20 x 20 cm (7.87 x 7.87 in.) metal plate onto a 5.8 KW butane gas
burner (or equivalent electrical heater), and then place a 7-9 g smoke pellet
onto the plate.
2. Place a metal chimney over the pellet. The chimney should be 2 to 6 mm
(0.08 to 0.24 in.) thick, at least 100 mm (3.94 in.) in diameter and 150 mm
(5.9 in.) high.
Either the base of the chimney or the metal plate should have ventilation
holes.
3. Ignite the burner and start the timer when the pellet starts to produce smoke.
4. Extinguish the burner after the required time has elapsed.
The amount of time depends on the room height and the temperature
differential (the temperature difference between the level at which the test is
conducted and the level at which the aspirating sampling points are
mounted). See Table 31 below.

Connectivity check
Ensure that communications between the detector and any fire control and
indicating equipment (especially alarm and fault conditions) operate correctly.
Check any other cause and effect requirements, particularly in relation to
integration with automatic suppression systems.

Questions and answers
does a system smoke detector require a box or can I mount it with just a ring
The Edwards ModuLaser system requires a backplane to be fixed to the wall for installation. The detector and display modules are then mounted onto this backplane. This suggests that a simple ring mount is not sufficient for installation.
