POWER TERMINAL - INPUT
LINE VOLTAGE CONNECTIONS
For the SHERLOCK 102/202, the power input needs to be
between 100 VAC and 240 VAC (Universal voltage) with a
maximum current of 0.8 Amps. Bring the power into the con-
trol and connect it as it appears on the power terminals labeled
at the bottom of the control.
Connections must utilize wire with a minimum insulation value
rating of 300 VAC.

NOTE: The SHERLOCK 102/202 Control System is a
Permanently Connected device. Ensure that the control power
source is wired though an external electrical cut-off switch or
through a 15 Amp circuit breaker. Locate the cut-off switch or
circuit breaker near the control unit.
GROUNDING REQUIREMENTS
The Earth Grounding Terminal on the Input Power Terminal
must be grounded in accordance to NEC and UL requirements.
Connect the grounding to the G Earth Grounding Connection.

HORN/STROBE, STROBE - OUTPUT
OUTPUT (+12VDC, RETURN) VOLTAGE CONNECTIONS
These terminals are supplied to power only Genesis International,
Inc. supplied alarm components. These are:
SHERLOCK STROBE LIGHT
SHERLOCK HORN AND STROBE ASSEMBLY
In general, to power the 12V DC alarm components when alarm
occurs, connect the +12VDC supply side to the alarm compo-
nents through the alarm relays and connect the return path
together. In most cases, the alarm component wiring is applica-
tion specified, please consult the application engineer.
Installation Requirements
1) Total current consumed by these alarm components and
sensors must not excess 3.0 Amps at 12VDC output. Refer
to component specification for their current ratings.
2) The equipment connected to this terminal shall have no
live, accessable parts.
3) The wire used to connect these devices to the Sherlock
Monitoring System shall have, at the minimum, an insula-
tion rating of 300VAC.
4) The wiring connection at the device connections shall
not be grounded.

ALARM RELAY OUTPUTS

The Alarm Relay Outputs on the 2-Series are a set of two Single
Pole Double Throw (SPDT) alarm relays for each alarm level:
K1 and K2 for alarm level 1, K3 and K4 for alarm level 2,
Optional Auxilliary Zone Isolation Alarm Relays for each sen-
sor can be factory ordered. Typical uses are:
K1/K2 Lower Alarm Level - Normally indicates the
"Permisible Exposure Limits (PEL)" conditions.
Connect to an audio-visual alarm and the Building
Automation System or an alarm dialing system.
K3/K4 High alarm function - Normally indicates 50% of the
"Immediate Danger to Life and Health (IDLH)" lev-
els. Connect to an audio/visual alarm and Emergency
Ventilation System.
Alarm schemes K1/K2 can be configured as a "fail-safe" alarm
scheme where the relay is "energized" (Opening the NC con-
tact) during non-alarm conditions and "de-energized" (Closing
the NC contact) during alarm conditions. This scheme will
allow a alarm signal to be produced if the Sherlock system were
to fail. Note that K2 and K4 are silenceable alarm relays that
can be silenced by the Alarm Silent Button at the front panel
when in alarm. Each relay circuit is connected via screw termi-
nals. Each circuit is a dry contacts signal with a 5.0 Amp Time
Lag fuse connected to the common leg.
Optional zone isolation alarm relay (K5 through K8) for each
sensor can be programmed to activate by level 1 or level 1&2
alarm. K6/K8 are silenceable and K5/K7 are non-silenceable.
This is a factory installed option and cannot be retro-fitted in
the field.
