HTI C9030T Instruction Manual

Instruction Manual of C9030T Conventional Optical Smoke Detector
------ Please read this Manual carefully before installing and using the product. -----
1. Product overview
C9030T Conventional Optical Smoke
hereunder) is a two-wire switch-type smoke-sensing detector. As a
non-polar two-wire connection is adopted in the detector, it is
compatible in conventional switch-type alarm control systems and
monitoring alarm systems. The detector can also be connected with
addressable fire alarm system via the zone module. The detector
monitors smoke concentration in the workplace in real time. While
monitoring, the red indicator blinks and the working current is low.
When the work site smoke concentration has exceeded the preset
alarm threshold, the alarm detectors and the red indicator remain on,
while the loop current is increased. The detector's alarm signal can be
locked and is displayed by changes in the loop current. The alarm can
only be reset by the instant power disconnection.
The detector is applicable in places where fire might generate
volume smoke, i.e. in industrial and civil buildings such as in the
restaurant, hotel, teaching building, office building, computer room,
archives and stack room.
2. Product features
1) Designed with an upper cover and a lower cover, it can be installed, debugged and maintained
conveniently.
2) Within a single-chip microcomputer, it can process the sampling data in real-time, save the latest
144 historical data and realize a curve tracing for the field situation.
3) It has a temperature, humidity and dust accumulation drift compensation function.
3. Technical parameters
1) Executive standard: EN54-7
2) Operating voltage: DC24V ±20%
3) Operating current: During monitoring <50uA.
In alarm mode 1mA~20mA (depends on the loop current limiting resistance).
4) Working indicator: During monitoring, the red indicator blinks once per 6 seconds.
In sensor failure alarm, the red indicator blinks twice per 6 seconds
In fire alarm mode, the red indicator remains on.
5) Weight: about 120g
6) External dimensions: diameter: 100mm, height: 58mm (with the base)
7) Wiring method: non-polarity two-bus system
8) Operating environment: Indoor, temperature: －10℃～+55℃; relative humidity: ≤95% (40℃±
2℃, without condensation)
9) Matched host machine: addressable fire alarm system via the zone module.

6. Installation and debugging
A self-contained complete base is necessary during the installation of a detector. As shown in Fig.4,
the model, the external dimensions, the mounting hole diameter and the mounting hole spacing of the
base are DZ-912K, Φ 100mm × 26.4mm (diameter × thickness), Φ 4.5mm and 44mm ～ 65mm
respectively.
Definitions of terminals(non-polarity
two-wire system):
1 – L2 Signal terminal
2 – L1 Signal terminal
3 – L1 Signal terminal
4 – No Pin
Notes：Terminal 2 and 3 are connected
directly inside the detector. Connecting
the detector with the controller as Fig.3,
we can find the failures caused by
dismounting the detector.
