C-TEC CA414 CAST Multisensor Fire Detector

The C-TEC CA414 is a CAST multisensor fire detector that combines optical smoke sensing with heat enhancement. It is third-party certified to EN54-5, EN54-7 and EN54-17, and works with C-TEC’s XFP and ZFP CAST-protocol addressable fire panels. It has a blue colour-coded ring, a white polycarbonate body and two bright red LED strips that give 360 degree visibility, and an on-board short-circuit loop isolator protects the loop.

Technical specifications

Five operating modes

The detector can be set from the panel’s PC programming tools to one of five modes that change the optical and heat triggers. High optical with Class A2 heat triggers at 0.1 dB/m and 62 degC, standard optical at 0.2 dB/m, standard optical with Class A2 heat is the default, and a low optical mode at 0.3 dB/m with heat at 62 degC suits less clean areas. The heat-only Class A1R mode at 56 degC is marked in the datasheet as not approved. This lets one detector type be used across areas with different nuisance alarm risk, for example near cooking areas or in plant rooms, instead of fitting separate smoke and heat heads, though the final selection is a fire engineering decision.

Installation and compatibility

The detector is fitted with a click-and-twist action to a CA408 CAST detector base, which has a locking mechanism against tampering, or to one of the listed CAST base mount devices; refer to the CA408 document DFU0002408 for wiring and fitting. It needs a 22 to 40 V DC loop and draws 370 uA in quiescent state. The datasheet also lists programmable heat and optical smoke variants as separate products. Because the protocol is CAST, it will not work on an Apollo or Hochiki loop, and the panel firmware and programming tools must support the device. The site also lists the C-TEC CP416 CAST-PRO optical smoke detector for CAST-PRO loops.

How the C-TEC CA414 works

The detector draws air through its chamber and measures the smoke with an optical sensor. A heat sensor adds to the reading. The detector samples once per second. It reports its state to the panel over the CAST loop. If a fire signal is found, the red LED strips light up.

Installation, commissioning and maintenance notes for the CA414

Fix the CA408 base to the ceiling and wire the loop. Plug the detector into the base. Set the operating mode from the panel software. Test the detector with a smoke test unit. Clean the detector head at the intervals the site plan sets.

CA414 operating modes

Five operating modes change the optical and heat triggers.

CA414 default mode

The default mode is standard optical plus Class A2 heat.

CA414 optical triggers

The optical triggers run from 0.1 to 0.3 dB/m.

CA414 heat trigger

The heat trigger is 62 degrees C in modes 1, 3 and 4.

CA414 operating voltage

The voltage is 22 to 40 V DC.

CA414 current draw

The quiescent current is 370 uA, and the alarm current is 5.5 mA.

CA414 indicators

Two red LED strips give 360 degree visibility.

CA414 loop isolator

An on-board short-circuit isolator protects the loop.

Detector records for the CA414

Record the address, the mode and the date of each test and cleaning.

Choosing the right CA414 mode

Choose a lower optical mode for less clean areas, so that dust does not trigger false alarms.
