Device Information and Programming

3.9814PH PHOTOELECTRIC SMOKE & HEAT DETECTOR & 814P PHOTOELECTRIC SMOKE ONLY DETECTOR

3.9.1GENERAL

The 814PH is a photoelectric smoke detector which also includes a temperature sensor. The detector senses the amount of smoke present and the temperature and sends these values to the MXP. The MXP makes any decisions as to whether this is an alarm, fault, normal or whatever, based on the smoke level, temperature, or rate of rise of temperature, and/or a combination of these. The integral LED is turned on by the MXP when an alarm is detected.

Refer to the specifications of the 814H for more details on the heat sensing element of the 814PH.

The 814P is the same as the 814PH, except that it has no temperature sensor.

The remote LED and functional base outputs are programmable for their functionality (refer to section 3.3).

3.9.3MX4428 PROGRAMMING OPTIONS - 814PH/814P

In the MX4428 programming there are two different device types that use the 814PH/814P detector. Type 16 814PH is used when the 814PH is used with the SmartSense algorithm and type 27 814PHFL is used when the FastLogic algorithm is required. These different device types allow the MX4428 to have separate sensitivity settings for the algorithms and for the sensitivities to be displayed correctly.

However, the mode value actually defines to the MXP which algorithm is to be used.

Mode values 0 – 7 must only be used with a device type of 814PH, and mode values 8 – 15 must only be used with a device type of 814PHFL. Do not use an incorrect mode, as the values displayed at the MX4428 will not match those being used or generated at the MXP.

The 814P must be programmed as an 814PH, with no heat. I.e. only modes 7 and 13 are allowed. The MX4428 will display the point type as 814PH.

The programmable values for the 814PH and 814P are described in the following tables.
