Whether or not to activate the alarm verification feature for such detectors is to be determined by the design engineer/ owner’s representative.

NOTE: Most applications of analog addressable smoke detectors do not require alarm verification to prevent nuisance alarms, unless there are transient ambient conditions, which may create problems. A short operational test period will usually provide information to determine this.

Systems with Alarm Verification must be permanently labeled to indicate that fact.

Air Sampling Tubes

The preferred method for providing support is to extend the intake tube through the far side of the duct, seal around the tube where it penetrates the duct wall, and plug the end with a rubber stopper. This facilitates visual inspection, intake tube cleaning, and injection of smoke or equivalent aerosol for testing the detector. Those over 36 inches long must
be provided with center support.

Addressable Monitor Modules shall be provided to connect (1) one non-addressable device or to supervise a non-addressable IDC zone (either Style D or Style B) of conventional type alarm initiating devices (any Normally Open [N.O.] dry contact device) to one of the Fire Alarm Control Panel Signaling Line Circuit Loops. Monitor modules shall be installed as required by the system configuration. All required monitor modules may not be shown on the Drawings.

  1. Indication of Operation: Unless otherwise indicated on the Drawings an LED shall be provided that shall flash under normal conditions, indicating that the Monitor Module is operational and in regular communication with the FACP.
  2. Mounting Requirements: Shall be mounted at the same height requirement as Notification Appliance devices in a clearly visible location.
Addressable Control Modules shall be provided to supervise and control the operation of (1) one conventional Notification Appliance Circuit (NAC) of compatible, 24 VDC powered, polarized Audio/Visual (A/V) Notification Appliances. For fan shutdown and other auxiliary control functions, the control module may be set to operate as a dry contract relay. The control module shall provide address-setting means using decimal switches and shall also store an internal identifying code that the control panel shall use to identify the type of device. An LED shall be provided that shall flash under normal conditions, indicating that the control module is operational and is in regular communication with the control panel. Control modules shall be rated for the load they control. (Inductive Loads require inductive rated modules.)

  1. Mounting Requirements: Shall be mounted at the same height requirement as Notification Appliance devices in a clearly visible location.
  2. Configuration: The control module NAC circuit may be wired for Style Y Class B with up to 1 Amp of inductive A/V signal, or 2 Amps of resistive A/V signal operation, or as a dry contact (Form C) relay. The control module shall be suitable for pilot duty applications and rated for a minimum of 0.6 amps at 30 VDC. The relay coil shall be magnetically latched to reduce wiring connection requirements, and to insure that 100% of all auxiliary relay or NACs may be energized at the same time on the same pair of wires.
  3. Power Source: Audio/visual power shall be provided by a separate supervised power loop from the main fire alarm control panel or from a supervised, UL listed remote power supply. A/V power sources and connections are not shown on the Drawings.
  4. Supervision required: The connection between individual addressable modules and their contact type initiating device(s) must be supervised.
Isolator Modules shall be provided to automatically isolate wire-to-wire short circuits on an SLC loop. The Isolator Module shall limit the number of modules or detectors that may be rendered inoperative by a short circuit fault on the SLC Loop.

Operation

Isolator Modules shall operate such that if a wire-to-wire short occurs, the Isolator Module shall automatically open-circuit (disconnect) the SLC loop. When the short circuit condition is corrected, the Isolator Module shall automatically reconnect the isolated section. The Isolator Module shall not require any address setting, and its operations shall be totally automatic. It shall not be necessary to replace or reset an Isolator Module after its normal operation.

To minimize the impact of a wiring fault on the system, isolation modules must be provided as follows:

  1. After each 25 devices/control points on any addressable circuit.
  2. For each circuit extending outside the building.
  3. In the FACP, at each end of the loop.
  4. On loops containing less than the 25 devices place an isolator at each end of the loop and one in the electrical center of the loop.

Mounting

The Isolator Module shall be wall mounted at the same height as A/V devices in a clearly viewable area in corridors. It shall provide a single LED that shall flash to indicate that the Isolator is operational and shall illuminate steadily to indicate that a short circuit condition has been detected and isolated.

Door hold open magnets shall be furnished with keepers, door chains, and other accessories as required to properly hold open doors as indicated on the Drawings. Holding force of the magnet shall be appropriate for the door to be held open. Door hold open magnets shall operate in a fail-safe manner, i.e., the door shall release in event of a failure of voltage to the device.

Power Supply

Door hold open magnets shall be configured to operate from a nominal 24 VDC system as supplied by the FACP or other power supply listed for the purpose. All hold open magnet supply sources, whether a part of the FACP or whether derived from a separate power supply, shall be supervised. Door hold open magnets which use step-down transformers, 120 VAC, or local relays are not acceptable. Magnets shall release on a power failure.

Device box support

Door hold open magnet device boxes shall be securely attached to the building structure by effective means. Boxes attached directly to only one metal stud or boxes supported by means of expansion type fasteners are not acceptable.

Wall mounted magnetic door holders and separate heavy-duty closers shall be used, instead of combination door control units. The electromagnets shall be controlled by the building’s smoke detection system FACP. Individual smoke detector auxiliary contacts shall not be used to release door holders.

Rolling Fire or Smoke Doors shall be motor operated. No manual reset doors are permitted.

Remote Power Supplies

Where remote power supplies are required, they shall meet the same requirements as those for the main fire alarm control panel, including the requirements for batteries and supervision.

Keys and Locks

All panels, terminal cabinets, and pull stations shall be keyed alike. Coordinate key/lock with the Owner’s requirements.

Automatic door locks controlled by the system must be either fail-safe magnetic locks or failsafe electro-mechanical with reverse bevel dead bolts.

All lock-protected doors must immediately unlock upon fire alarm, loss of AC power, disablement of the fire alarm system (defined as loss of 24 VDC power) or upon manual operation of an unlocked supervised switch at a constantly attended location.

Provide the following spare parts with the system, each individually packaged and labeled. For multi-building projects, calculate separately for each building:

  • Fuses: 2 of each size used in system
  • Isolation Modules: 2% of installed quantity
  • Manual Stations: 2% of installed quantity
  • Indoor Horns/Strobes: 4% of installed quantity
  • Spot Smoke Detectors, Bases: 6% of installed quantity
  • Heat Detectors: 6% of installed quantity
  • Monitor/Relay Modules: 2% of installed quantity

Increase decimal quantities of spare parts to the next higher whole number. For example, if a system has 20 spot-type smoke detectors, provide 2 spare detectors with bases.
