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

·

  Solo A5 Smoke Detector Tester Gas

P/N SOLOA5-001

·

  Testifire 1001 / 2001 P/N TS3-001

Strictly follow the testing instructions provided on the gas
canister  label.  After  applying  the  test  gas  for  1-2
seconds,  the  smoke  alarm  will  occur  within  4-10
seconds. If not, check the Test Mode and repeat the test.
Do not repeat the test multiple times or apply the test gas
too long – this will cause CO-troubles.

CAUTION

DO  NOT  use  at  distances  smaller  than  2  feet  (0.6 m)
from  detector.  Spray  the  test  gas  for  a  period  of  1-2
seconds.  Excessive  spraying  may  affect  the  detector’s
sensitivity and cause CO sensor troubles.
* 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.

CAUTION

DO NOT use any test gas other than the one mentioned
above  as  compatibility  to  the  CO  sensor  cannot  be
assured.

CO DETECTOR FUNCTIONAL TEST (CO TEST GAS)

The fire control panel must be programmed to test mode
prior  to  performing  a  functional  (*  Go-No-Go)  CO  gas
entry test. Failure to do so may result in 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.
Test  by  activating the  detector  using the  approved  CO
test gases:

·

  Siemens CO Test Gas P/N 500-650053

·

  SDI Solo C3 or C6, P/N SOLOC3-001, SOLOC6-001

·

  HSI CO Check, P/N HO-CO2S

·

  Testifire 1001 / 2001 P/N TC3-001

Following the instructions with product and provided on
the CO gas canister label. Spray the CO gas stream into
the detector opening from the opposite side of the alarm
indicator  LED  a  distance  of  approximately  2 inches
(5 cm) from the CO sensor to the straw of the test gas
can  is  required.  Use  only  short  (approx.  1-2  seconds,
BUT NOT LONGER THAN 2 seconds) activation of the
gas  can.  After  applying  the  test  gas  for  1-2s,  the  CO
alarm will occur within 4-10 seconds. If not, please check
the Test Mode again and repeat the test. Do not repeat
the test multiple times or apply the test gas too long –
this will cause CO-troubles.
* This test is simply used to ensure that a CO gas can
reach the CO sensor and alarm the control panel when
the  detector  reaches  the  programmed  obscuration
(concentration) level.
The OOHC941 detectors can also be tested individually
using  the  DPU.  Refer  to  the  DPU  Manual,  P/N 315-
033260.
