MACURCO CONTROLLERS & DETECTORS (CONT.)
SS102HC-1 SENSOR OPERATION
The SS102HC-1 is a microcomputer controlled sensor. It has a 2 1/2 minute warm up cycle, during which its outputs
progressively increase from 1.0 to 2.1 volts. The internal switch must be set to volts. The green LED type light turns on and off
during the 2 1/2 minute warm up cycle. At the end of the warm up cycle, the light switches to a steady on, to indicate normal
operation. See the Carbon Monoxide Transducers data sheet for more technical information.
The SS102HC-1 is supervised. Various critical operating parameters are measured and any problems are indicated by the
green light turning off and the output going to a high voltage (about 2.9v), to cause the control panel to actuate the exhaust fan.

STABILIZATION TIME
Although the units will be fully operational within a few minutes of being first powered, the SS102H gas sensor requires up
to 7 days to reach its final operating point and the SS102HC-1 up to 3 days. The unit is intended to be continuously powered.

SENSOR POISONS
The gas sensing tip in the detector is designed with extreme sensitivity to the environment. As a result, the sensing
function of the tip may be deteriorated if it is exposed to a direct spray from aerosols such as paints, silicone vapors, etc., or to a high
density of corrosive gases (such as hydrogen sulfide, sulfur dioxide) for an extended period of time.

SERVICING OF UNIT
The SS102H & SS102HC-1 do not require regular maintenance. The units use a self purging semi-conductor sensor that
has a 7-10 year life expectancy. All maintenance and repair of products manufactured by Macurco, Inc. are to be performed at the
Macurco manufacturing facility. Macurco does not sanction any third-party repair facilities.

SS103-3A & SS103-10A GENERAL INFORMATION
The SS103-3A Controller supplies all power to, and receives information from up to three SS102H or SS102HC-1 Carbon
Monoxide Sensors. The panel can control three fans or two fans and one alarm circuit.
The SS103-10A Controller supplies all power to, and receives information from up to ten SS102H or SS102HC-1 Carbon
Monoxide Sensors. The panel can control three fans, or two fans and one alarm circuit.
Please refer to the Automatic Exhaust Fan Controllers For Parking Garages data sheet for more technical and wiring
information.

SS103 INSTALLATION
Mount the SS103 panel in the desired location. Knock out (SS103-3A) or drill (SS103-10A) conduit access holes in bottom
of the case for the 120VAC power, sensor cables and fan control cable. The sensor connections are in the upper center of the panel.
The power connections are in the lower right corner and the fan connections in the lower left corner.
When the SS103-3A is opened, so the cover of the knock out box is to the left, remove the two small screws on the right
side of the inner panel ONLY. Lift the right side, and the inner panel hinges to allow access to the circuit board. On the SS103-
10A, loosen the two clamping screws on the right side of the unit to gain access to the circuit board.
The 120 VAC power for both the SS103-3A & 10A systems requires less than two amps. Match the cable from the relay
contacts to the size of the load. The maximum power that the relays can switch is 10 Amps at 240 VAC.
The sensors are low voltage (12V) and low voltage cable (4 conductor #18 or larger) can be used, with or without conduit.

SS103 WIRING
All connections are clearly labeled. Each group of four terminals (A, B, C & D) connects to one SS102H or SS102HC-1
sensor. Each zone numbered (1 to 10) matches the front panel designation. For the SS102H set up color coding for the wires to
make sure that terminal designations match: A to A, B to B, C to C & D to D. On the SS102HC-1 the two Red wires go to the C &
D terminals on the SS103 control panel, the White wire goes to terminal A, and the Black wire goes to terminal B.
The Fan control relays are normally de-energized. They energize to turn on the fans. Only the normally open and common
relay contacts are connected to the terminal strip. Therefore, Fan relays in two or more SS103 panels can be connected in parallel to
control the same Fan. WARNING: a magnetic starter will be needed to control the fan motors. The SS103 relays are for pilot duty
only.
