The emergency power supply required by Sentence (1) shall be capable of providing: The emergency power supply required by Sentence (1) shall be supplied from: “3.2.7.8 Emergency Power for Fire Alarm Systemsįire alarm systems, including those incorporating a voice communication system, shall be provided with an emergency power supply conforming to Sentences (2), (3), and (4).
#IGUARD VOLTAGE INDICTION ALARM CODE#
Because it's based on the National Building Code I'm pretty sure the wording and references are good for other provinces.
Let's review the British Columbia Building Code Division “B” Part 3.
#IGUARD VOLTAGE INDICTION ALARM FULL#
“B” means you have to ensure battery is rated correctly to ensure the system's full load capacity meets the requirements of the relevant sections of the Building Code (or local ordinance) for the type of occupancy and “P” of the referenced Standard. “A” refers to battery type which means it's either a sealed lead acid (SLA), wet lead, ni-cad, or some other type as “recommended by manufacturer”. It specifically states “each battery shall be inspected and tested to confirm operability”! If your system has more than one set of batteries, they MUST be tested and the INDIVIDUAL results recorded in the inspection report!
NOTE: Ensure that the battery is within the charging capacity of the battery charger, as recommended by the manufacturer.” In liew of the above battery tests, replace the battery with a new set having a current date code, amp-hour capacity and of a type as recommended by the manufacturer of the fire alarm system. (Refer to Appendix F3, Battery Capacity Meter Test) or (Refer to Appendix F2, Silent Accelerated Test) orĪ battery capacity meter test. Required supervisory load for 24 h followed by the required full load operation, orĪ silent test by using the load resistor method may be used for the full duration test (Refer to Appendix F1, Silent Test) or Perform battery tests demonstrating specified battery operation as follows, after which the battery voltage should not be less than 85% of its rating after the tests, otherwise replace batteries (Refer to Appendix F, Battery Tests). “6.3.2 Each battery shall be inspected and tested to confirm operability, including the following functions, as applicable (Refer to Appendix C2.5, Emergency Power Supply Test and Inspection):Ĭorrect type as recommended by manufacturer Ĭorrect rating as determined by battery calculations based on full system load Section 6.3 is entitled POWER SUPPLIES and it states: Let's review the relevant sections of CAN/ULC-S536-13 as they apply to battery and power supply testing. The common control (located in the basement) had the same size batteries with a supervisory current of 790 mA. I was told that this was the size of the batteries originally supplied with the system (that Edwards had engineered the system this way). The 26 AH batteries were replaced last year. In this example the supervisory current is 998 mA (close enough to be 1 Amp).

This is a Chubb-Edwards EST-3 command centre with a graphic annunciator in a high-rise building in Burnaby (it's also the subject of the discussion I outlined in the introduction to this Series (it's unfortunately escalated to a full blown complaint now). Supervisory current on that particular pair was 5.18 Amps. The same 18AH batteries are installed there. The amplifier cabinet is next to this one. In order to get at this particular switch, you have to remove the panel "dead-front". This is a common occurrence in large networked systems because it makes testing and set-up "easy". Notice the switch installed in the cabinet next to the batteries. The meter reading here is 2.878 Amps - that's the supervisory current for the main control and display module you're looking at. The batteries in the cabinet are date coded for 2009 (which means they were probably replaced during the last inspection in December). This is a Simplex 4000 networked system located in a twin high-rise complex equipped with an emergency generator. With the power "off", I show a supervisory current draw of 450 mA. I think we can safely assume the batteries were replaced in 2007. This is an Edwards QS (QuickStart) panel located in a small strip mall in Chilliwack.
