Section 3: Programming Options
This section describes the programming options available via DIP switch settings. The HPFF can
be field-programmed using DIP switch SW1 on the Control circuit board. Refer to the following
illustration for switch location and DIP switch settings for ON and OFF positions.

3.1 DIP Switch Settings
The following table lists the programmable features and the switch settings required to select a
particular feature. A detailed description of each is presented in the following pages.

SW1 DIP Switch
1
SIG 1/2 “A”
2
SIG 1/2 “A”
1 OFF, 2 OFF
= Pass-through (of Steady On, sync, or coded; DO NOT use with full-wave rectified input).
1 ON, 2 OFF
= Temporal.
1 OFF, 2 ON
= Sync generator (see switches 5 & 6).
1 ON, 2 ON
= Pass-through Filtered (use for full-wave rectified inputs).

SIG 3/4 “B”
3 OFF, 4 OFF
= Pass-through (of Steady On, sync, or coded; DO NOT use with full-wave rectified input).
3 ON, 4 OFF
= Temporal.
3 OFF, 4 ON
= Sync generator (see switches 5 & 6).
3 ON, 4 ON
= Pass-through Filtered (use for full-wave rectified inputs).

SYN SEL “A”
5 OFF, 6 OFF
= Cooper Wheelock
5 ON, 6 OFF
= System Sensor
5 OFF, 6 ON
= Amseco and Faraday
5 ON, 6 ON
= Gentex
7
AC 2HR
OFF
- No delay in Trouble reporting with an AC failure.
ON
- 2 hour delay in Trouble reporting with an AC failure.
See Sections 3.2.3 and 3.2.4 for further details of TB2 immediate AC Fail and programmed
no delay/delayed Trouble contacts.

SIG SEL
This switch works in conjunction with the initiating device signal input(s) and switches 1 through 6 to
determine General Alarm*, Split Alarm**, or Silencing***.
8 ON
= Split Alarm**
• NAC outputs 1 and 2 are controlled by Signal Input 1.
• NAC outputs 3 and 4 are controlled by Signal Input 2.
8 OFF, Signal Input 1 ON, Signal Input 2 ON
= General Alarm* on all four NAC outputs.
8 OFF, Signal Input 1 ON, Signal Input 2 OFF
= Silencing*** of all four NAC outputs.
*
General Alarm
is visual strobe and audible horn activation.
**
Split Alarm
is Signal Input I controlling NAC outputs 1 and 2, and Signal Input 2 controlling NAC outputs
3 and 4.
***Silencing
is visual strobe activation but audible horn is silenced for the initiating device.
