TNA TXC7141 CONVENTIONAL MANUAL CALL POINT

Description

The TXC7141 is a conventional manual call point designed for fire alarm systems. It features a press-activated plastic dome which sends an alarm signal to the connected fire panel when pressed. After activation, a special key is required for reset, helping to prevent accidental resets.
The device operates on a conventional two-wire, non-polarised system and is suitable for indoor use in standard ambient conditions. 

Key Features

• Operating Voltage: DC 24 V (range 16-28 V) for wide system compatibility. 

• Very low standby current: ≤ 20 µA, which reduces load on fire circuits.

• Alarm current: ≤ 30 mA, indicating an efficient signal output. 

• Passive output contact: Rated DC 30 V / 0.1 A for external device control; contact resistance ≤ 100 mΩ. 

• Two-wire non-polarised wiring simplifies installation.

• Operates in ambient range: −10 °C to +55 °C, humidity ≤ 95% RH non-condensing. 

• Dimensions: 90 mm × 90 mm × 34 mm (with base); Weight ~ 90 g.

Industrial Uses / Applications

• Manual fire alarm activation in offices, schools, retail locations

• Corridor and lobby mounting for occupant-initiated alarm detection

• Conventional fire detection systems in smaller or retrofit installations
