8.0 Memory, Day Mode, Night
Mode, and Remote Walk Test
The Memory, Day Mode, Night Mode, and Remote
Walk Test require a supply voltage on Terminal M to
activate. The supply voltage must range from 6 VDC to
18 VDC.
Use the switch (Figure 8) or an external power supply
(Figure 9).
• Control Voltage: +6 VDC to +18 VDC = ON
(Switch Closed); 0 VDC = OFF (Switch Open)
• Day Mode: Disables the alarm memory and allows
the LED (if activated) to operate normally.
• Memory: Activated when the DS9370-BEL is in the
Night Mode. This allows the detector to store an
alarm for display at a later time. Memory Mode
requires the LED jumper to be in the ON position.
• Night Mode: Enables the alarm memory and
disables the LED operation.
• Remote Walk Test: Remotely enables LED
operation from Terminal M for walk testing. This
feature is used when LED operation is disabled; the
LED jumper in the OFF position.
Refer to Table 4 for the desired action, control voltage,
and LED jumper position.

After the cover is closed, secure the entire assembly
using the supplied anti-vandal screw (Figure 10).
8.3 Maintenance
At least once each year, verify the detector’s range and
coverage. For continuous daily operation, instruct the
end user to walk through the far end of the coverage
pattern to verify alarm output before arming the system.
