INSTALLATION / REMOVAL OF DETECTOR
TO INSTA LL:
·
Rotate detector counterclockwise while gently pressing
on it until the detector drops fully into base.
·
Then rotate the detector clockwise until it stops and locks
in place. Insert optional locking screw (Order Model
LK-11).
TO REM OVE:
·
Loosen locking screw, if installed. Then rotate the
detector counter clockwise until stop is reached.
·
Pull detector out of base.
LED INDICATOR OPERATION
The OP121/OH121 contains an LED indicator capable of
flashing either one of three distinct colors: green, yellow, or
red. The microprocessor based detector monitors the
following:
·
Smoke in its sensing chamber
·
Smoke sensitivity is within the range indicated on the
nameplate label (sensitivity verification)
·
Internal sensors and electronics
Based on the results of these checks, the LED indicator
flashes as follows:

TESTING AND MAINTENANCE
To assure proper operation of the detector and control panel, it
is required that both the Sensitivity test and the Functional test
be conducted using the procedures outlined below.
SENSITIVITY TEST
The
OP121/OH121
automatically and requires no test equipment. A green flash of
the detector LED about every 10 seconds indicates that the
smoke sensitivity is within its listed limits.
FUNCTIONAL TEST
To test the detector and control panel for functional operation,
use SIEMENS Test Gas, P/N 500-649750. Follow the
instructions on the gas canister label.
Smoke entry test mode: To test the detector for smoke entry,
place the detector into a test mode. The test mode condition is
automatically started after the initial power up and after every
reset for a period of 3 minutes. It is recommended that a
control panel reset be performed after every smoke entry test
is conducted to restart the 3 minute test period. The test mode
is indicated when the green LED is double blinking every 10
seconds. A normal operational mode is indicated

Detector and control panel functionality can also be tested
using the TM121 test magnet as shown in Figure 4 for the
OP121 detector and Figure 6 for the OH121 detector. Place the

magnet in the specific area at the bottom of the detector that is
2½
shown in Figure 5 for the OP121 detector and Figure 7 for the
OH121 detector for at least 5 seconds with the colored side
towards the centered LED. The detector will send an alarm to
the panel.
WARNING: Testing with the magnet only tests the circuit; it
does not test the detector's sensing ability.
WARNING: The TM 121 test magnet is a strong magnet that
can be harmful to pacemaker wearers and to those with
medical implants. Keep the magnet away from magnetic
sensitivity
media such as credit cards and memory disks/chips.
CAUTION:
DETECTOR HEAD TO BE DISASSEMBLED. NO REPAIRS
OR CLEANING SHOULD BE ATTEMPTED.
DO NOT PAINT
The detector/base plastic 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.
