Heat Alarm - Installation

POSITIONING

positioning.svgLocations of alarms must be compliant with either BS 5839: Part 6 or relevant Building Regulations if in any doubt. This alarm is not intended for any non-residential, commercial or industrial application, nor for any other purpose other than described in the above. For the best protection, heat alarms should always be installed as part of a complete fire protection system that includes smoke alarms.

Make sure you:
  • Install smoke alarms in circulation areas at a distance no greater than 7.5 m from the farthest wall, no greater than 7.5 m from a door to any room in which a fire might start and no greater than 7.5 m from the next smoke alarm.
  • Install heat alarms on the ceiling, ideally in the centre of the room.
  • Install sufficient alarms to compensate for closed doors and obstacles.
  • Install your heat alarm at a distance no greater than 5.3 m from the farthest wall, no greater than 5.3 m from a door to any room in which a fire might start and no greater than 5.3 m from the next heat or smoke alarm.

Do not:

  • Install the alarms within 1500 mm (1.5 m) of a fluorescent light fitting and keep wiring at least 1000 mm (1 m) from these fittings.
  • Install alarms on circuits containing fluorescent light fittings or dimmer switches.
  • Install alarms within 300 mm (12”) of light fittings or room corners.
  • Install smoke alarms in wall positions that are less than 100 mm (4”) or more than 300 mm (12”) away from the ceiling.
  • Locate the Thermoptek smoke alarm close to bathrooms or showers as it can be susceptible to nuisance alarms from steam.
  • Install heat alarms on a wall.

 

HARDWIRE INSTALLATION

The alarm base plate is designed to be permanently mounted, using it’s own builtin terminal block to connect it to the mains. The base plate can be screwed directly to the ceiling.

WARNING: Wiring should be installed by a qualified electrician in accordance with BS7671. We advise you to follow the new harmonized cable colour coding as specified in BS7671.

IMPORTANT: The circuit used to power the alarm must be a 24 hour voltage circuit that cannot be turned off by a switch. BS 5839: Part 6 states that: For mains
powered alarms, each with an integral standby supply (Grade D), the mains electricity supply should take the form of either a) an independent circuit at the dwelling’s main circuit board, in which case no other electrical equipment should be connected to this circuit (other than a dedicated monitoring hardwire-installation.svgdevice installed to indicate failure of the mains electricity supply to the alarms); or b) a separately electrically protected, regularly used local lighting circuit.

  • Ensure a permanent connection to the fixed wiring of the building is made in a suitable junction box.
  • Remove the terminal block cover.
  • If trunking is required, snap the breakout tab away from the base plate prior to connection.
  • The wiring must be connected to the terminal block as follows:

Live (L) - Connect to the Live in the house wiring.
Neutral (N) - Connect to the Neutral in the house wiring.
Interconnect (I) - If desired, join the Interconnect wire between the alarms.
Use the Earth terminal to safely terminate any copper Earth or green / yellow cable.

WARNING: Mixing the Live and Neutral connections when interconnecting alarms will damage all the alarms. DO NOT use the Earth wire for the interconnect connection.

Either feed the wire through the hole in the base plate or through the YT2 trunking.

Line up the alarm with the base plate and gently apply pressure until the alarm clicks into place. Switch on the mains electricity supply.

Check that the green LED is on and that the red LED is flashing once approximately every 45 seconds. The LEDs are located on the front of the alarm.


HARDWIRE INTERCONNECT MULTIPLE ALARMS

For multiple alarm installations use a ‘three core and earth’ style cable between all the alarms to be interconnected. Connect the interconnect cable between each alarms ‘I’ terminal. The interconnect wire (minimum 0.75 cable) must be treated as Live, it should be insulated and sheathed.

Do not:

  • Exceed the maximum of 30 interconnected alarms on a network.
  • Exceed 250 m of connecting wire per circuit.
  • Connect FireAngel Pro alarms to any other models produced by another manufacturer.

WIRELESS INTERLINK

You can wirelessly interlink up to 50 products within the Wi-Safe 2 product range. They are not designed to communicate with wireless alarms from other ranges or manufacturers. These alarms need to be ‘learned-in’ or interlinked in order to communicate with each other. If one alarm activates, all other interlinked alarms will also sound. Wi-Safe 2 eliminates the need for interconnecting wires around a property making future system modifications easy and cost effective. AC Smoke and Heat alarms will still need a mains supply in accordance with BS 5839: Part 6 and Building Regulations.


IMPORTANT: Obstructions such as steel reinforcement in concrete could block or impede the wireless signal. While the wireless range is over 200 m in clear air /
clear line of sight, the effective range may be reduced by walls and other obstructions in the building. It is recommended not to exceed 35 m as the maximum distance between alarms in a network.
Do not:

  • Exceed the maximum of 50 alarms interlinked in a network.
  • Connect FireAngel Pro alarms to any models produced by another manufacturer.
