Put on your thinking caps, give that rabbits foot keychain a big squeeze and answer these five (5) really simple questions for your chance at winning one of three (3) fabulous prizes and some pretty special bragging rights! Simple because the answers can be found on our website (you may need to brush up on your searching skills).
1. Calculate the minimum fuel capacity for a generator in a 32 storey residential apartment (the low fuel alarm setpoint) for a fire alarm system with three power supplies with the following current draws (note – the derating factor for your calculations is 1.2):
Control Panel
Audio Power #1
Audio Power #2
Supervisory Current
1.2 Amps
7.2 Amps
4.9 Amps
Alarm Current
2.4 Amps
11.6 Amps
7.8 Amps
Batteries Provided
12AH
60AH
45AH
Generator Load = 75% for 30 minutes, 25% operating load for time remaining Maximum Fuel Capacity (100%) = 300 Gallons
Generator Fuel Consumption Table
25% (gph)
50% (gph)
75% (gph)
100% (gph)
350 kWh

Now calculate the required battery capacity for the above fire alarm system if it is NOT connected to the emergency power panel.
2. Describe the difference between a Style “A” and Style “C” DCL loop.
3. Describe how would you perform the required annual testing for each DCL Loop Style in a four storey residential building with an underground parkade?

A stairwell location with sprinkler isolation valves & flow switches for two adjacent floors;
The top of a stairwell with a sprinkler isolation valve & flow switch for that floor and an addressable smoke detector.
An elevator shaft pit addressable fire detector and a top of shaft addressable smoke detector
5. In which Code or Standard is the requirement for elevator pit automatic fire detection stipulated?
