The minimum load on the alarm output must exceed 5mA at 12V for proper supervision operation.
UL
If a device such as a siren driver with a high-resistance trigger input (drawing less than 5mA) is used in a UL
Household Fire installation, the siren driver must independently supervise siren speaker wiring.
Using a Siren Driver
To install a siren driver, perform the following steps:
Step Action
1 Mount the siren driver in the panel’s cabinet.
2 Wire the siren driver to the control and to the speaker(s). (See the driver’s instructions.)
3 Cut the blue jumper on the upper left-hand corner of the panel’s PC board.

Telephone Line Connections
Connect the main dialer output to telephone company lines using the cable supplied.
UL
The telephone line inputs have overvoltage protection in accordance with UL1459, as specified in UL985/UL1023.
The system is shipped defaulted for Contact ID format. It is the only format capable of uniquely reporting all 250
zones, as well as openings and closings for all 250 users. This requires central stations to be equipped with the
Honeywell MX8000 receiver or equivalent. If you need an update, contact your distributor.
To prevent the risk of shock, disconnect phone lines at the telco jack before servicing.
If the communicator is connected to a PABX, be sure it has a backup power supply that can support the PABX for 24
hours (central station) or 60 hours (remote station). Many PABXs are
not power-backed up, and this can result in a
communication failure if power is lost .
Reporting Formats
The system supports the following formats:
ADEMCO Contact ID; ADEMCO 10-Digit Contact ID and 4 + 2 Express.
