FUNCTIONAL TEST
Perform a functional (Go, No-Go) test by activating the
detector using the following test gases:
·
Smoke Sabre, P/N SMOKESABRE-01-001
·
Smoke Centurion (M8), P/N M8-001-024
·
Solo A5 Smoke Detector Tester Gas
P/N SOLOA5 001
·
Solo A10, P/N SOLO A10 / A10s
·
Testifire 1001 / 2001, P/N TS3-001
·
HSI PurCheck, P/N HO-30S
·
HSI SmokeCheck™, P/N HO-25S
Follow the instruction on the gas canister label. This test
is simply used to ensure that smoke can enter the
sensing chamber and alarm the control panel when the
detector reaches the programmed obscuration
(concentration) level.
The FDOT421 detectors can also be tested individually
using the DPU.
Refer to the DPU Manual, P/N 315-033260.
MAINTENANCE
The control unit automatically indicates the trouble
message for the FDOT421 detector whose smoke
chamber changes to the level where the set sensitivity
cannot be maintained. In such circumstances, the
detector may require replacement.
CAUTION
Under no circumstances is the detector head to be
disassembled.
No repairs should be attempted.
DO NOT PAINT
The detector is marked DO NOT PAINT. This is intended
to prohibit painting during routine maintenance of the
occupancy which can affect proper operation of the
detector.
