D127 Reversing Relay Module

www.boschsecurity.com

The D127 Reversing Relay is a dual alarm reporting
module. It can report alarms over a direct wire line to
meet insurance and local municipal requirements.
When mounted in an enclosure with a compatible
control panel, the D127 can report two separate alarm
conditions to the central station. The D127 Reversing
Relay supplies a contact reversal for one alarm
condition and a repeating flip/flop (reversal/normal/
reversal) mode for a second alarm condition. The relay
output can be dry contact switching or voltage/current
reversing, depending on the requirements of the
receiving station.
