WIRING
The OP121/OH121 should be connected as shown in Figure 3 using the separate mounting base, Model DB-11.
Follow the control panel wiring connection drawing installed on the inside face of each control panel cover. See DB-
11 instruction, P/N 315-094193, for base mounting. Duplicate wiring information is also in the Installation, Operation,
and Maintenance Manual provided with every control panel.
Note any limitations on the number of detectors and restrictions on the use of remote devices permitted for
each circuit.
WARNING!
Connect detector only to control units specified in detector and panel literature or system may
not operate.
AVERTISSEMENT!
Connectez le détecteur uniquement aux unités de contrôle spécifiées dans la documentation du
détecteur et de la centrale, faute de quoi le système pourrait ne pas fonctionner.

connector)
DETECTOR MOUNTING
TO INSTALL:
Rotate detector counterclockwise while gently
pressing on it until the detector seats fully into base.
Then rotate the detector clockwise until it stops and
locks in place. Insert optional locking screw (Order
Model LK-11).
TO REMOVE:
Loosen locking screw, if installed. Then rotate the
detector counterclockwise until stop is reached.
Pull detector out of base.
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.
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
Internal sensors and electronics
Based on the results of the monitoring, the LED indicator
flashes the following:

Normal supervisory operation. Smoke
sensitivity is within rated limits.
