Intrusion Systems | ISM‑BLA1‑LM Blue Line Nightlight Module

The Blue Line ISM-BLA1-LM Nightlight Module attaches to
the Blue Line detectors. When the detector senses a
presence, the module's LEDs light and provide
illumination up to the equivalent of bright moonlight
(0.1 cd at 30 cm [1 ft] from the detector).

Unique Interface
The Blue Line Nightlight Module mounts on top of and is
wired to a Blue Line detector. This unique interface
between module and detector makes installation fast,
easy, and inexpensive. Once the detector is mounted and
wired to the control panel, you simply add the module
with no additional wiring needed.
Basic Operation
The nightlight module has a photo-sensor and four LEDs
under a diffusing lens. It mounts on, draws its power
from, and is controlled by any Blue Line detector. Once
installed and set, if the detector senses motion and the
photo-sensor does not detect light, the LEDs light.
Settings
Brightness
The brightness level can be set for low or high by
positioning a jumper during module installation.
Duration

The length of time the LEDs remain lit is set with an
external switch on the side of the module. Short duration
is approximately 20 sec to 30 sec; while long duration is
approximately 2 min to 4 min.
On-Off
Use the external On or Off switch on the side of the
module to determine if the LEDs light when motion is
detected.
Field Testing
The module comes with a piece of black plastic for
covering the photo-sensor for field testing the module.
