Fire Fighting Enterprises FIRERAY 100R User Manual

Reflective

Optical Beam Smoke Detector

User Guide

1. Installation

 IMPORTANT NOTE: The infrared beam path MUST be kept clear of obstructions at

all times! Failure to comply may result in the system initiating a Fire or Fault signal

 Detector installation must comply with local regulations. UL listed products must comply

with NFPA72

 Ensure clear line of sight between Detector and Reflector – it is recommended at least

0.5m radius of clear space be maintained around the centre of the beam path

 Mount securely to solid structural surfaces
 Position beam as high as possible, but with a minimum distance of 0.5m from Detector to

ceiling. For installations complying with UL268/NFPA72, the maximum distance of
Detector and Reflector from the ceiling must be 10% of the distance between floor and
ceiling

 Mount Detector and Reflector directly opposite each other
 Do NOT position Detector where personnel or objects can enter beam path
 Do NOT position two Detectors facing each other
 Do NOT install the Detector or Reflector in environments where condensation or icing are

likely to occur

 For ranges between 5m and 50m, use a 50m Detector with 1 Reflector.
 For ranges between 50m and 100m, use a 100m Detector with 4 Reflectors.

2. User Configuration Settings

Access to the configuration settings is through the back plate of the Detector Head. Factory
default configuration settings are marked .

Dip switch

Function 1 2 3 4
Auto Reset Fire Relay (5 seconds) ON
Latching Fire Relay OFF
Fire Relay Enable, On Compensation Limit OFF
Fire Relay Disable, On Compensation Limit
50% Threshold OFF OFF
35% Threshold OFF ON
25% Threshold ON OFF

12% Threshold (Use for extreme sensitivity
requirements)

 The Detector is set to Latching Mode or Auto Reset Mode using DIP Switch 1. If in Auto

Reset Mode, the Detector will automatically recover from a Fire state when the fire
condition has been removed. If in Latching Mode, it will remain in Fire state until either the
Detector is placed in Prism Targeting Mode or Alignment Mode, then back to Operating
Mode, OR power is removed from the Detector for 10 seconds.

 Fire Relay Enable/Disable on Compensation Limit is set with DIP Switch 2. This mode

selects whether Fire activation is still enabled during an AGC Compensation Fault.

 The Sensitivity of the Detector is set using DIP Switches 3 and 4.
 Do not use the 12% or 25% Alarm threshold for UL listed 100m Detectors, as this will not

conform to UL268
