&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;True North Automation&amp;#039;&amp;#039;&amp;#039; is an automation company located at 7180 11 St SE, in Calgary, Alberta, Canada.  The building was built in 1982, and the fire alarm system is mostly original.&lt;br /&gt;
&lt;br /&gt;
==System Specifications==&lt;br /&gt;
====FACP====&lt;br /&gt;
The building is protected by a Simplex 4010 conventional fire alarm system.  The panel is located in the main floor elevator lobby.  The system coding is likely temporal.  &amp;lt;br&amp;gt;This panel replaced a Pyrotronics System 3.&lt;br /&gt;
&lt;br /&gt;
====Notification Appliances====&lt;br /&gt;
Most notification appliances are Pyr-A-Larm BDC-624C vibrating bells (6&amp;quot; gong).  &amp;lt;br&amp;gt;Some areas have Mircom BL-6B motor bells (6&amp;quot; gong), and other areas have Edwards &amp;quot;Durabel&amp;quot; 6100D vibrating bells (6&amp;quot; gong).&lt;br /&gt;
&lt;br /&gt;
===Initiating Devices===&lt;br /&gt;
====Pull Stations====&lt;br /&gt;
Most pull stations are Pyrotronics MS-51 conventional single-action pull stations.  &amp;lt;br&amp;gt;Some areas have Mircom MS-401 conventional single-action pull stations as deficiency replacements.&lt;br /&gt;
&lt;br /&gt;
====Automatic Detection Devices====&lt;br /&gt;
There are Mirtone 73330 conventional 135°F fixed-temperature heat detectors in some rooms.  &amp;lt;br&amp;gt;There are Potter CR-135W conventional 135°F fixed-temperature/rate-of-rise heat detectors in all kitchens.  &amp;lt;br&amp;gt;There are Edwards C2M-PD conventional photoelectric smoke detectors at the top of each stairwell, and in one automation lab.  &amp;lt;br&amp;gt;There are System Sensor 1400A conventional ionization smoke detectors in all server rooms and in one automation lab.&lt;br /&gt;
&lt;br /&gt;
====EOLs====&lt;br /&gt;
There are Simplex 2081-9040C end of line resistor plates on all circuits.&lt;br /&gt;
