Recommended Detector Wall Mounting / Detector Guard Orientation
1. Mount box on wall with exterior mounting holes (1) in upper left and lower right position.
2. Mount detector base to 4-inch square box with locking hole (2) on left top.
3. When 4-inch square box and detector base are mounted as shown, detector LED will be in recommended 0°
position with detector inserted in base. When mounting the STI-9604 mechanical guard (3) on wall or ceiling, use
orientation indicated.

SMOKE DETECTOR FUNCTIONAL TEST (SMOKE
TEST GAS)
The fire control panel must be programmed to test mode
prior to performing a functional (* Go-No-Go) smoke
entry test. Failure to do so may result in a test failure.
Refer to the specific control panel installation operations
manual for proper “test mode” programming instructions.
To determine how to put the control panel in “test mode”,
specific programming instructions are located in the
panel documentation.
To activate the detector with test gas, only use the
following test gases:
·
HSI SmokeCheck™ testgas P/N HO-25S
·
HSI PurCheck P/N HO-30S
·
Smoke Sabre Smoke Detector Tester P/N
SMOKESABRE-01-001
·
Smoke Centurion (M8), P/N M8-001-024
·
Solo A5 Smoke Detector Tester Gas
P/N SOLOA5-001
·
Testifire 1001 / 2001 P/N TS3-001
* 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 OOH941 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 OOH941 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.
REPLACEMENT OF A DETECTOR IN AN EXISTING
SYSTEM
Detectors with product version
≥
30 (UL268 7th, Isolator
mode) have some minor differences to devices which
were built before product version 30. In case a legacy
Detector needs to be replaced in an existing system,
please follow these instructions.
Alarm Verification:
Legacy Detectors have 3 Sensitivity Settings with
integrated Alarm Verification
2.50 % / ft Threshold, verified
3.00 % / ft Threshold, verified
3.50 % / ft Threshold, verified
Alarm verification is removed in detectors with product
version
≥
30. If the panel configuration remains
unchanged, the alarm verification feature is no longer
available. If alarm verification is required, update the
panel to the latest revision.
