MP1502 Door Controller (ADC-AC-MP1502) - Installation Guide

MP1502 hardware

Wiring and DIP switch setup

Status LEDs

Factory reset

The factory reset function can be used for the following purposes:

• Reset the controller back to the factory settings
• Erase any previously configured static IP settings
• Erase all configuration and cardholder database information
• Recover from database corruption causing MP1502 board to continuously reboot

Bulk erase configuration memory

The bulk erase function can be used for the following purposes:

• Erase any previously configured static IP settings
• Recover from database corruption causing MP1502 board to continuously reboot

This command erases all local hardware settings associated with the controller (except for Static IP settings). Once the communication is restored to the controller, all settings that are saved on the Partner Portal will be sent down to the controller, and all doors associated with it will return back to their default state (i.e., locked or unlocked).

Note: A bulk erase will not remove information from the Customer Website and app. Information will only be removed locally at the controller. All users, rules, schedules, and access plans on the Customer Website and app will remain.

Input power

The MP1502 requires 12 to 24 VDC power.

• Locate power source as close to the unit as possible.
• Connect power with minimum of 18 AWG wire.
• Connect the GND signal to earth ground in ONE LOCATION within the system! Multiple earth ground connections may cause ground loop problems and is not advised.
• Observe POLARITY on 12 to 24 VDC input.
• There are two dedicated inputs for cabinet tamper and UPS fault monitoring. Normal (safe) condition is a closed contact. If these inputs are not used, install a jumper wire.

Reader and expansion module wiring 

Each reader port can be used to wire one Wiegand or OSDP reader. Power to the readers is selectable: 12 V DC, or power is passed-through (PASS) from the input voltage of the MP1502 (TB300-VIN), 600 mA maximum per reader port. Readers that require different voltage or have high current requirements must be powered separately. Refer to the reader manufacture specifications for cabling requirements.

For more information regarding which position the reader power selection jumper (J503) should be in, see When should the MP1502 Door Controller (MP1502) be set to use PASS or 12V for the reader power?.

For readers with two LED wires, only connect the wire controlling the green LED to the MP1502. The serial I/O device communication port (TB1501) can support up to sixteen Alarm.com expansion modules using a 2-wire RS-485 bus. The maximum cable length is 4,000 feet (1,219 m).

Note: For Wiegand installations remove the OSDP end of line jumper on J1501 for reader 1 or J1502 for reader 2 for proper reader function.

Relay wiring

Four Form-C contact relays are provided for controlling door lock mechanisms. Each relay has a Common pole (C), a Normally Open pole (NO),and a Normally Closed pole (NC).

When momentarily delivering power to unlock the locking hardware (fail secure), the Normally Open and Common poles are used. When momentarily removing power to unlock the locking hardware (fail safe), the Normally Closed and Common poles are used. Check with local building codes for proper egress door installation.

Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature failure of the relay plus affect the operation of the MP1502 Door Controller. For this reason, it is recommended that a diode be used to protect the relay. Wire should be of sufficient gauge to avoid voltage loss.

Input wiring

Inputs are used to monitor door position switches or request-to-exit devices. Input circuits can be configured as unsupervised or supervised. When unsupervised, reporting consists of only the open or closed states.

When configured as supervised, the input circuit will report not only open and closed but also open circuit, shorted, grounded*, and foreign voltage*. A supervised input circuit requires two resistors be added to the circuit to facilitate proper reporting. The standard supervised circuit requires 1k ohm, 1% resistors, and should be located as close to the sensor as possible.

Note: Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL.

22 AWG minimum required for input wiring. 18 AWG recommended if wiring request-to-exit devices in series with
locking hardware.

The input circuit wiring configurations shown are supported but may not be typical:

Specifications

The interface is for use in low voltage, Class 2 circuits only.

The installation of this device must comply with all local fire and electrical codes. For more information about specifications, see MP1502 Door Controller (ADC-AC-MP1502) - Data Sheet.

UL294 Performance Levels ULC 60839-11-1 Indoor use

The models described in the manual are recognized boards intended to be used with ULC 60839-11-1 enclosures, power supply readers, controllers, I/O boards, and an off premise monitoring station to form a grade 2 or higher system. Units maybe used in grade 4 system installations provided the full system with this board integrated is verified in the end use application. The boards mentioned have only been evaluated for their specific function for grade 2 requirements. For ULC 60839-11-1 an enclosure with a tamper is required and a reader and power supply is to be verified in the end product, as well as the operations need to be documented in the installation instructions.

The interface is for use in low voltage, Class 2 Circuits only.

The installation of this device must comply with all local fire and electrical codes. Units are to be installed in accordance to NFPA 70. UL verified 12 to 24 V DC. The unit is to be powered with a UL listed UL 294 approved power supply with a class 2 power limited output.
