The SB Series is a 6" polarized base with annunciator output featuring a current limiting resistor, transient protection and a blocking diode to enhance annunciator function. The SB Series Smoke Detector base is designed specifically for use with the Potter Smoke Detector Models IS-24, PS-24 and PS-24H.
These detectors will not work without power. They must be properly connected into the signal initiating device circuit of a fire control panel that is listed as being compatible by Underwriters Laboratories, Inc. These detectors will not sense fires which start where smoke does not reach the detector.
Fires on other building levels, within walls, on roofs , in chimneys, or on the other side of closed doors may not be detected.
Fires from explosions, improperly stored flammable liquids, escaping gas, arson or fires resulting from inadequate fire protection practices may not be detected.
Smoke detectors should be tested upon completion of installation and at least semi-annually thereafter, in accordance with the section of “Inspections, Tests, and Maintenance” in NFPA-72.
To Install the Detector: Insert the detector into the base, turn the detector clockwise until it locks, then tighten the vandal resistant allen screw.
Caution: These units must be installed and maintained in accordance with all applicable NFPA standards, local codes and any authority having jurisdiction. Please refer to NFPA- 72 Standards for Automatic Fire Detectors for installation guidelines, and testing procedures.
The POTTER ELECTRIC BPS Series can be used in all areas where Photoelectric Smoke Detectors are required. It is suited for smoldering or flaming fires.
The BPS Series photoelectric smoke detector utilizes two bicolored LEDs for indication of status. In a normal standby condition the LEDs flash Green every 3 seconds. When the detector senses that its sensitivity has drifted outside the UL listed sensitivity window the LEDs will flash Red every 3 seconds. When the detector senses smoke and goes into alarm the status LEDs will latch on Red.
The unit is comprised of an LED light source and silicon photo diode receiving element. In a normal standby condition, the receiving element receives no light from pulsing light source. In the event of fire, smoke enters the detector and light is reflected from the smoke particles to the receiving element. The light received is converted to an electronic signal.
Signals are processed in the comparator, and when two consecutive signals exceeding the basic level are received within a specific period of time, the time delay circuit triggers the SCR switch to activate the alarm signal. The Status LED lights continuously during alarm period.

The POTTER ELECTRIC DSD Series duct smoke detector provides early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial and Residential applications. The DSD is designed to prevent the recirculation of smoke in areas by the air handling systems, fans and blowers. Complete systems may be shut down in the event of smoke detection. The POTTER ELECTRIC DSD-I and the DSDP operate on 115 VAC, 24 VAC and 24 VDC.
The DSD Series is designed and built to meet all local requirements, as well as the NFPA regulations regarding duct smoke detectors. Output terminals are provided for remote accessories such as a horn, strobe, remote status indicators and reset key switches or push buttons.
Air sampling is accomplished by two tubes which protrude into the duct. An exhaust tube of one standard length (7.5") is supplied in the installation kit with the smoke duct unit. Once the duct width has been determined the air intake sampling tubes must be ordered. Sampling tubes are supplied in three standard lengths 2.5 ft., 5 ft. and 10 ft. and cut to size to fit the duct. Mounting the duct smoke unit is accomplished by the use of a template and 4 sheet metal screws, which are provided. Mounting can be achieved without the removal of the clear cover which is secured by 4 capture screws.
The compact DSD contains 3 sets of alarm contacts, 1 set of form “C” contacts rated at 10 amps, 1 set of form “A” contacts rated at 10 amps, 1 set of form “A” contacts rated at 1 amp. There is also 1 set of form “C” 10 amp trouble contacts for monitoring detector head removal, and the failure of the input supply voltage.
The pilot and alarm visual indicators provided on the front of the DSD duct unit, signal the operating status of the device. A manual test/reset switch is located along side the visual indicators. This switch can be defeated by cutting a jumper on the PCB.

Carbon Monoxide (CO) is a toxic odorless, tasteless, colorless gas that is present whenever organic compounds are involved in combustion. Many homes utilize either propane, natural gas or wood for heat and cooking purposes and the burning of these fuels produce CO. A malfunctioning appliance or fuse will fill a space with this toxic gas completely unknown to the occupants.
The Potter CO 12/24 utilizes the premium Carbon Monoxide (CO) detection technology for accurate detection and false alarm immunity. The CO 12/24 will only respond to the presence of CO and will not react to other ordinary household chemicals that affect other detectors. When the CO is detected, an 85 decibel sounder and the alarm relay activate to indicate the presence of CO. The sounder can be silenced for four (4) minutes by pushing the Reset button.
The CO 12/24 operates on 0-28 VDC supplied by an intrusion or fre system. The device emits a Temporal 4 pattern when the presence of CO is detected. In addition to monitoring for tampering, the detector also monitors the sensor and detects if an internal problem exists. If a fault occurs within the detector, the trouble/service a horn activates and the trouble relay. This monitoring feature also complies with the sensor end-of-life requirement. The CO 12/24 has a 6 year warranty and life span. After 6 years, the detector needs to be replaced.
The PS-24 can be used in all areas where Photoelectric Smoke Detectors are required. The wide range smoke chamber makes the PS-24 well suited for fires ranging from smoldering to flaming fires.
SB Series Style bases may be used with the PS-24. Current interchangeable/compatible devices are the IS-24 ionization detector.
OPERATIONThe PS-24 photoelectric smoke detector utilizes two bicolored LED's for indication of status. In a normal standby condition the LED's flash green every 3 seconds. When the detector senses that its sensitivity has drifted outside the UL listed sensitivity window the LED's will flash red every 3 seconds. When the detector senses smoke and goes into alarm the status LED's will latch on red.
The detector utilizes an infrared LED light source and silicon photo diode receiving element in the smoke chamber. In a normal standby condition, the receiving element receives no light from the pulsing LED light source. In the event of a fire, smoke enters the detector smoke chamber and light is reflected from the smoke particles to the receiving element.
The light received is converted into an electronic signal. Signals are processed and compared to a reference level, and when two consecutive signals exceeding the reference level are received within a specified period of time, the time delay circuit triggers the SCR switch to activate the alarm signal. The status LED's light continuously during the alarm period.

Model SPB-24N Stock #1430027
The SPB-24N Projected Beam Smoke Detector consists of an emitter and receiver. The projected beam smoke detector should be placed so that smoke generated by a fire will likely rise into the path of the beam. The receiver is constantly monitoring and measuring the intensity of the beam transmitted by the emitter. Should the smoke from a fire cause a decrease in the signal strength of a magnitude that exceeds the programmed obscuration setting, an alarm signal is generated.
The SPB-24N Projected Beam Smoke Detector can provide vital fire detection in applications where other type detectors may not be able to respond quickly, or at all, to a fire condition. Examples of some applications where projected beam smoke detectors have been successfully used include: atriums, gymnasiums, theatres, museums, factories, tunnels, churches, stables, anechoic chambers and high air velocity areas.
The SPB- 24N Projected Beam Smoke Detector may also be used in conjunction with more traditional spot type smoke detection devices to provide an even more comprehensive detection system.
For more information on how to install the SPB-24N Projected Beam Smoke Detector consult the SPB-24N Installation Instruction Guide and the applicable NFPA Standards for additional guidance.
OPERATIONThe near infrared pulsed beam generated by the emitter is sensed by the photodiode of the receiver, where it is converted into an electrical signal. This signal is then amplified and applied, via an analog to digital converter, to a microprocessor. The normal state signal (the initial beam data) once stored in the microprocessor is used as reference for comparison with subsequent beam signals.
When there is a difference between actual beam strength and stored reference data that exceeds the programmed alarm obscuration reference level, a fire signal is produced. A trouble signal is generated if the beam is more than 90% obstructed (as opposed to partially obscured by smoke).
The microprocessor also provides compensation for a change in received signal value, with time, caused by contamination of the optics. Since such a change with time appears as a slow change in the beam signal, the microcomputer compensates in such a manner that the signal moves closer to the reference data at a rate approximately +1% per hour. When this compensating capability reaches a limit, the microcomputer automatically generates a trouble signal.
A calibrated test filter is available upon request to test and verify the sensitivity setting of the projected beam smoke detectors.
Features: • Microprocessor based for reliability • Simple setup & alignment with signal strength LED’s • Provides 60 feet on center linear protection at a range of 32.8 feet to 328 feet • Automatic compensation for signal drift or dirty lens • Three field adjustable sensitivity settings • Form A alarm and Form B trouble contacts • Calibrated filters available to verify sensitivity • Color-coded emitter and receiver labels for easy recognitionc
