The included LDB-3 control module has a disable input which is ideal for two-button emergency phones, such as
Viking's E-1600-20A, allowing "Info" button calls to be placed without activating the relay (turning on the emergency
strobe light, camera, etc.) Three DIP switches are provided for turning ring detection on or off, off-hook/loop detec-
tion on or off and for selecting a ring cadence mode which allows the relay to follow ringing or to remain activated
during the off time of standard ring cadence.
The control module can be installed on any standard telephone line or analog PABX/KSU station. The 1 million can-
dle power strobe can be interfaced to flash on ringing, off-hook or a combination of ringing and off-hook (line in-use).
The LDB-3 ring/loop detect control module is also available separately, see DOD# 409 for more information.
The BLK-3-EWP is equipped with Enhanced Weather Protection (EWP) for outdoor installations where the unit is
exposed to precipitation or condensation. EWP products feature foam rubber gaskets and boots, sealed connec-
tions, gel-filled butt connectors, as well as urethane or thermal plastic potted circuit boards with internally sealed,
field-adjustable trim pots and DIP switches for easy on-site programming. For more information, see DOD# 859.
The kit includes: (1) LDB-3 control module, (1) blue strobe light, (1) 12V DC power adapter, (13) gel-filled butt con-
nectors and (1) single gang weatherproof mounting box with gaskets and hardware.

Provide Strobe Light
Indication of Line Status
Ideal for Use with Two-Button Emergency Phones!
The BLK-3-EWP provides high visibility indication of analog line status
through a high powered one million candle power strobe light. The BLK-
3-EWP is the ideal solution for the hearing impaired and can be used
equally well in loud warehouses or factories, where ringing phones can not
be heard. Alternatively, the BLK-3-EWP can be used to add emergency
notification to pre-existing emergency phones by turning on the strobe
light when the emergency phone is in use.
