Addressable manual call point used with an intelligent two-bus control panel

Addressable manual call point

I. Product overview

The 960E addressable manual call point (manual call point for short) is mainly designed to be used with an intelligent two-bus control panel. If it is pressed after a fire is manually confirmed, an alarm signal may be sent to a fire alarm control panel which will, after receiving the alarm signal, display the coded address and the equipment status of the manual call point. When the manual call point is operating normally, the red indicator will blink; when there is a fire alarm, it will remain lit. The manual call point supports electronic coding and has a built-in fire telephone jack and a PHONE indicator, making its engineering application convenient. 

II. Product features

• It can realize complete electronic coding and in situ rewriting with help of a coder.
• Designed with an upper cover and a lower cover, it can be installed, debugged and maintained conveniently.
• It is designed with a two-wire fire telephone jack and is therefore more applicable to engineering application.
• Designed with passive output contacts, it can control other external equipment directly through an intermediate relay.
• The pressing sheet on the manual call point will not get crushed after it is pressed, but can be reset by a special tool, so it can be used repeatedly.

III. Technical parameters

1. Executive standard: GB19880-2005
2. Operating voltage: 24V (pulse modulation)
3. Operating current: ＜300uA (in the monitoring status); ＜2mA (in the action status)
4. Output contact: Normally open contact; capacity: 0.1A/30VDC
5.  Weight: About 120g
