Digital Monitoring Products Inc PC0124 User Manual

The 1105 Series are two input transmitters that are typically used for door/window applications.  The 1105 Series 

provides an internal case tamper, internal magnetic reed switch and an on-board terminal block to allow for 

external contact wiring.  Both sets of contacts, internal and external, can be programmed to operate at the same 

time allowing for two independent zones from one transmitter.  The 1105-EOL provides one internal magnetic reed 

switch, a wall tamper, and an on-board terminal block to allow for external contact wiring with an end-of-line 

resistor. Refer to the panel programming guide for zone programming information.

All DMP 1100 Series Wireless Receivers and Panels

The 1105 Universal Transmitter includes the following items:

•  One 1105 Transmitter PCB mounted in a two-part housing

(base and cover)

•  Magnet with standard housing and base

•  One 3V lithium CR123A Battery

•  Hardware pack

•  Zone name and number label

•  Serial number label

•  Optional Commercial magnet housing

The 1105-EOL Universal Transmitter includes the following items:

•  One 1105 Transmitter and all components listed above

•  One Model 312 470K EOL Resistor

For your convenience, an additional pre-printed serial number 

label is included.  Prior to installing the device, record the serial 

number or place the pre-printed serial number label on the panel 

programming sheet.  This number is required during programming.  

As needed, use the zone name and number label to identify a 

specific transmitter.

Refer to the XR500 Series Programming Guide (LT-0679), XR100

Series Programming Guide (LT-0896), or the XT30/XT50 Series

Programming Guide (LT-0981) as needed. Program the device as a

zone in 

Zone Information during panel programming.  At the Serial 

Number: prompt, enter the eight-digit serial number. Continue to

program the zone as directed in the panel programming guide.  
Note:  When a receiver is installed, powered up, or the panel is reset, the supervision time for transmitters is reset.  

If the receiver has been powered down for more than one hour, wireless transmitters may take up to an additional 

hour to send a supervision message unless tripped, tampered, or powered up.  This operation extends battery life for 

transmitters.  A missing message may display on the keypad until the transmitter sends a supervision message.

The 1105 Transmitter provides a built-in survey capability to allow one person to confirm transmitter communication

with the receiver while the cover is removed. The 1105 Transmitter PCB Red Survey LED turns on whenever data

is sent to the receiver then immediately turns off when the receiver acknowledgement is received.  Pressing the 

tamper switch is a convenient way to send data to the receiver to confirm operation. When the tamper switch

is pressed or released, the LED blinks once to indicate proper operation.  When the transmitter does not receive 

an acknowledgement from the receiver the LED remains on for about 8 seconds to let you know communication is 

not established. Communication is also faulty when the LED flashes multiple times in quick succession. Relocate

the transmitter or receiver until the LED immediately turns off indicating the transmitter and receiver are 

communicating properly. Proper communication between the transmitter and receiver is verified when for each

press or release of the tamper switch, the LED blinks immediately on and immediately off.   

Repeat this test to confirm five separate consecutive LED blinks. Any indication otherwise  

means proper communication has not been established.
