INSTALLATION INSTRUCTIONS

General Information

The Door Control Module (DCM) is used to control access points, or doors. When connected between door hardware and the Main Logic Board, the DCM accepts data from card readers and/or keypads, and operates the electromagnetic devices used to lock and unlock the door. The DCM mounts in a standard cabinet and communicates with the system’s MLB via a twisted pair network connection.

Each DCM provides all the inputs and outputs necessary to manage two single-reader access points or one two-reader access point.

Power Requirements

When mounted in a cabinet with a dedicated power supply, the DCM obtains its power from the LOCAL (J1) power output connection of its associated power supply. When added to a cabinet along with an MLB or other module, the DCM obtains power from the power supply’s REMOTE (J5) power output.

The DCM board requires 10.5-14VDC @ 170mA, but its actual current requirement will be determined by the addition of the current requirements of two card readers (or keypads), which are typically 90mA each. The DCM also provides two power supply monitoring inputs: Low Battery and AC Loss. These two inputs are compatible with the corresponding monitoring outputs of the PassPoint PTDPSU power supply only. (Do not enable AC or Low Battery monitoring without first wiring the power supply.)

DCM Relay Outputs

In addition to card reader inputs, each DCM has two Form C, voltage-supervised output relays. These relays are used to operate electromagnetic door locks or doorjamb mounted lock strikes. Use appropriate transient suppression for the installed locking devices.

All DCM relays may be used as committed resources to control access points. For instance, one of the operating parameters that can be configured for DCM relays is the length of time that the relay output is energized when allowing entry or exit through an access point. DCM relays cannot be commanded ON or OFF when used as a committed resource. Instead, the access point these relays are assigned to must be bypassed or locked.

The relay output circuitry provides for a supervision input (30VRMS or 30VDC max.) which, when connected to the common contact of the relay, indicates that a voltage of more than approximately 4VDC or 4VAC is present at the relay contacts. The supervision input is rectified and filtered before going to the comparator, therefore DC & AC voltages can be supervised. The module's firmware doesn't know or care if the voltage is DC or AC. This supervision can be useful to determine if the power supply that is used to power a connected load is fully operational. Each relay can be programmed to monitor the relay contact voltage or to ignore it.

PTDCM (SA12020) specifications

Guardian Technologies PTDCM (SA12020) is an innovative product designed to enhance air quality in various environments. This air purification system leverages advanced technologies to deliver clean and fresh air, making it ideal for homes, offices, and commercial spaces.

One of the main features of the PTDCM is its multi-stage filtration system. This system includes a pre-filter that captures larger particles such as dust and pet hair, ensuring that the air being circulated is free from common allergens. The true HEPA filter follows, which is capable of capturing 99.97% of particles as small as 0.3 microns, including smoke, mold spores, and pollen, thus providing superior air purification.

In addition to the HEPA filter, the Guardian Technologies PTDCM incorporates an activated carbon filter. This component excels at removing odors from the air, including those from pets, cooking, and smoke. By combining these filtration methods, the PTDCM offers comprehensive air cleaning capabilities, making it a versatile solution for many indoor environments.

The PTDCM is equipped with UV-C light technology, which works to kill airborne viruses and bacteria. This additional layer of protection enhances the overall effectiveness of the air purifier, particularly in high-traffic areas or settings where hygiene is critical. The UV-C feature can be a game-changer in controlling pathogens, providing peace of mind to users concerned about air quality.

Another remarkable aspect of the Guardian Technologies PTDCM is its user-friendly design. The device typically features a simple control panel that allows for easy adjustments between several fan speeds and operating modes. Additionally, many models come with smart features, such as air quality sensors that automatically adjust the filtration speed based on the detected air quality.

The PTDCM also boasts a compact and stylish design that fits seamlessly into any decor. Its lightweight construction makes it easy to move from room to room, allowing users to ensure clean air wherever they need it most.

With its commitment to promoting healthier indoor air, the Guardian Technologies PTDCM (SA12020) stands out in the air purification market. Its advanced filtration, UV-C technology, and user-friendly features make it a reliable choice for anyone looking to improve their indoor environment. As awareness of air quality grows, the PTDCM represents a proactive approach to creating a clean and safe living space.
