1.  In order to give the digital alarm communicator transmitter the ability to disconnect an incoming call to the 

protected premises, telephone service should be of the type that provides for timed release disconnect.

2.  Network access and domain access policies shall be set to restrict unauthorized network access and “spoofing” 

or “denial of service” attacks.

3.  Select Internet Service Providers that have redundant servers/systems, Back-up power, Routers with Firewall 

enabled and Methods to identify and protect against “Denial of Service” attacks (i.e. via “spoofing”).

4.  Power for network equipment as hubs, switches, routers, servers, modems, etc., shall be backed up or 

powered by an un-interruptable power supply (UPS), stand-by battery or the control unit, capable of facilitating 

24 hour standby, compliant with Clauses 16.1.2 and 16.4.1 of CAN/ULC-S304-06.

5.  Where such cannot be facilitated, the control unit shall support back-up communications for a secondary 

communications path, subject to the following:

Low Risk and Medium Risk shall use a dialer as a minimum;

High Risk shall use cellular control channel or long range radio as a minimum; and

Very High Risk shall be equipped with 24 Ah standby power. Note: Refer to Table 11 of CAN/ULC-S304-06 for the 

risk levels.

6.  If the lines (numbers) are in a single hunt group (See definition in CAN/ULC-S304-06), they shall be individually 

accessible; otherwise, separate hunt groups shall be required. These lines shall be used for no other purpose than 

receiving signals from a digital alarm communicator transmitter. These lines (numbers) shall be unlisted.

7.  Installation guidelines for communication channel security shall be provided with the control and/or 

communicator module to instruct on compliance to Subsection 15.2 of CAN/ULC-S304-06, Active Communication 

Channel Security.

8.  Products or components of products used in communication channels, which perform communications 

functions only, shall comply with the requirements applicable to communications equipment as specified in 

CAN/CSA-C22.2 No. 60950-1, Information Technology Equipment-Safety - Part 1: General Requirements. Such 

products or components include, but are not limited to: Hubs, Routers, Network interface devices, Third party 

communications service providers, Digital subscriber line (DSL) modems, and Cable modems.

9. Communication devices powered by 24 hr UPS.

10. If the lines (numbers) are in a single hunt group (See definition in CAN/ULC-S304-06), they shall be individually 

accessible; otherwise, separate hunt groups shall be required. These lines shall be used for no other purpose than 

receiving signals from a digital alarm communicator transmitter. These lines (numbers) shall be unlisted.

11. A timed release disconnect requirement applies to the telephone lines (numbers) connected to the digital 

alarm communicator receiver. The numbers assigned to the digital alarm communicator receiver shall be 

individually accessible, even where they are connected in rotary (hunt group). 
12. Receiver shall be connected to the signal receiving centre emergency electrical power supply per CAN/ULC-S301.

This is an alphabetical list of terms used in the SCS-1R Receiver system operating instructions.  Refer to these 

explanations for additional information.

ACK - Acknowledge an alarm signal by pressing any top row Select key on the Membrane Keypad.  

Alphanumeric - A set of characters consisting of either the letters A through Z, the digits 0 through 9, special 

symbols, or a combination of all of these.  For example, the set of characters “AB76#2,” is alphanumeric.

Character - One of a set of symbols that can be arranged in groups to express information.  This includes the 

digits 0 through 9, the letters A through Z, punctuation marks, and other special symbols.

Command Processor Programs - The data programmed into a DMP Command Processor™ panel at the time of 

installation.  A typical program includes: communication information, system options, area information, 

Programs zone information, and the number and type of Security Command® keypads in the system.  This 

should not be confused with System Programs that are software routines used by the SCS-1R to execute 

functions described in the Operations Manual.

COMMAND - The key on the Membrane Keypad used to scroll through programming and enter programming information. 

LCD Membrane Keypad - A 32-character Liquid Character Display that displays information and provides a 

Membrane Keypad that allows you to enter information.

Default Value - A value assigned to a prompt by the SCS-1R.  The SCS-1R Receiver assigns the value to that prompt 

allowing the operator to accept its entry and respond to the next prompt.

Entry - Information typed into the SCS-1R through the LCD Membrane Keypad mounted in the front of the  

SCS-1R.  This information is entered into the system when the COMMAND key is pressed.

Prompt- A single item of information on the LCD.  For example, a prompt within the System Configuration program 

would be the company name.  

Menu - An LCD display that lists the program selections available to the operator.

Numeric - Description of numerical information.  For example, the set of characters 1 2 3 4 5 is numeric.

User Number - The sequential number assigned to each user code number by the panel during its programming.  

This is the number transmitted to the SCS-1R Receiver.  The actual code number is never transmitted.
