Simplicity 252/M Ananlogue Addressable Fire Alarm Panel (SP-252/M)

The Simplciity plus is the ideal introduction to the world of addressable fire alarm panels.

As its name suggests, it has been designed with ease of use in mind, using pre-programmed value for its programming options.  The installer simply needs to configure the loop and enter text labels via the built in keypad (optional).

The Simplicity Plus 252 has user definable zones, option for zonal or common alarm operation, options for I/O operation, alarm verification and user selectable languages.

It can be connected to an RS232 desktop printer for real time event log printing (Epson LQ300+ recommended) and it can also drive a serial repeater model AD-REP (Part No. 37-156).

Alarm Verification

To helpprevent false alarm causing a full evacuation, any smoke detector can be set to alarm verification mode with a time delay of between 30 seconds and 4 minutes.  Should any of these detectors go into alarm then only the detector's LEDS and sound/flasher base (if connected) will activate.  Should the alarm not be cleared with this time delay then a common alarm will occur.

Zonal Addressing

All devices are assigned to a specific zone based on their address.  This removes a programming step and helps to streamline the commissioning process.  The following table outlines which address fall in which zones.

• 1: Address 1 - 32      - Zone 1
• 1: Address 33 - 64    - Zone 2
• 1: Address 65 - 96    - Zone 3
• 1: Address 97 - 126  - Zone 4
• 2: Address 1 - 32      - Zone 5
• 2: Address 33 - 64    - Zone 6
• 2: Address 65 - 96    - Zone 7
• 2: Address 97 - 126  - Zone 8
