GFE-AD SERIES, Addressable Photoelectric Smoke, ROR & Fixed Temperature Heat Detector and Combined Smoke + Heat Detector Installation Wiring Diagram

TYPICAL WIRING DIAGRAM When installed, terminals 4 and 6 are for connection of remote LED

THE GFE-AD SERIES DETECT ORS MUST BE CONNECTED

TO A COMPATIBLE ANALOGUE ADDRESSABLE FIRE ALARM

CONTROL PANEL.

THE INSTALLATION MUST BE IN COMPLIANCE WITH THE

CONTROL PANEL SYSTEM INSTALLATION MANUAL.

WARNING TO PREVENT DETECTOR CONTAMINATION AND SUBSEQUENT

COVERED UNTIL THE AREA IS CLEAN AND DUST FREE.

GENERAL DESCRITPTION GFE-AD series consists of: Photo electric smoke detectors, Rate of

Rise and Fixed temperature detectors and combined smoke / heat

detectors with advanced analogue addressable communications. DIP

switches are provided for setting the detector’s address.

GFE-AD-S: Analogue addressable smoke detector

GFE-AD-S-L: Analogue addressable smoke detector with remote LED

output

GFE-AD-SH: Analogue addressable smoke and rate-of-rise and fixed

temperature heat detector

GFE-AD-SH-L: Analogue addressable smoke and rate-of-rise and

fixed temperature heat detector with remote LED output

GFE-AD-H: Analogue addressable rate-of-rise and fixed temperature

heat detector

GFE-AD-H-L: Analogue addressable rate-of-rise and fixed

temperature heat detector with remote LED output

Note: The base model no. for GFE-AD-S, GFE-AD-SH and GFE-AD-H

is P/N772912. The base model no. for GFE-AD-S-L, GFE-AD-SH-L and

GFE-AD-H-L is P/N774912.

INSTALLING THE BASE 1. To insure proper fit of the detector head to the base, all wires

should be properly dressed at installation:

(A) Position all the wires flat against terminals.

(B) Fasten the wires away from connector terminals.

2. The detectors are intended for ceiling or wall mounting in

accordance with

local Fire authority recommendations.

3. The base of the smoke detector can be mounted directly onto

most standard electrical junction boxes without using any type of

mechanical adaptor. For surface wired installations the base

adaptor P/N 882912 for two wire, P/N

884912 for four wire. has cable entry points to accept standard

electrical conduit.

INSTALLING THE HEAD 1. Set the desired address via DIP switch on the back of the detector,

see ADDRESS SETTING section.

2. Align the components as shown in Figure 2.

3. Fit the detector head onto the base and twist clockwise to secure

it.

4. After all detectors have been installed, apply power to the control

unit and activate the detection Loop.

5. Test the detector(s) as described in the TESTING section of this

manual.

Note: Do not install the detector head until the area is

thoroughly cleaned of construction debris, dusts, etc. Please

refer to control panel technical information regarding the

maximum number of detectors installed on the same loop.

TESTING All remote signaling systems, releasing devices and extinguishing

systems should be disconnected during the test period and

reconnected at the conclusion of testing.

SMOKE SENSOR TESTING Allow smoke from a cotton wick or a test smoke aerosol to enter the

detector-sensing chamber for at least 10 seconds. When sufficient

smoke has entered the chamber, the detector will signal an alarm, this

being indicated by illumination of the red LED. Make sure to clear smoke

out of the chamber before resetting in order to keep the detector

at its current sensitivity setting.

HEAT SENSOR TESTING The detector to be tested should be subject to a flow of warm air at

a temperature of between 65°C and 80°C. (This requirement can

be met by some domestic hair dryers).

Proceed as follows:

1. Switch on the warm airflow and check that temperature is

+LOOP

PANEL

INVALIDATION OF WARRANTY, THE SMOKE DETECTOR MUST REMAIN

correct and stable.

2. From a distance of several inches, direct the airflow at the

guard protecting the thermistor. The detector should alarm

within 60 seconds.

3. Upon alarm immediately remove the heat source and

check that the red LED of the detector is illuminated.

4. If a detector fails to activate within 60 seconds, confirm

connections and programming. If necessary replace and

return to distributor for recalibration.

NOTE: After testing, check that the system is returned to

normal operation. Notify the appropriate authorities that

the testing procedure has been completed and the

system is active again.

MAINTENANCE

The recommended minimum requirement for detector

maintenance consists of an annual cleaning of dust from the

detector head by using a low power vacuum cleaner.

CAUTION: DO NOT ATTEMPT TO DISASSEMBLE THE

DETECTOR. THIS IS A SENSITIVE DEVICE AND IS NOT

INTENDED TO BE OPENED FOR SERVICING BY USERS.

OPENING THE DETECTOR HEAD WILL VOID THE

WARRANTY.
